3 Description
The TCA39416 is a 2-bit bidirectional MIPI I3C v1.1.1, I2C, SMBus and SPI voltage-level translator with an output enable (OE) input and rising and falling edge accelerators. It is operational from 0.72 V to 1.98 V on both the A-side and B-side with V CCA must be less than VCCB for proper operation. This limitation allows the device to interface between lower and higher logic signal levels at any of the typical 1-V, 1.2-V and 1.8-V supply rails. The OE input pin is referenced to V CCA, can be tied directly to VCCA, but it is also 1.98-V tolerant. The OE pin can also be controlled and set to a logic low to place all the Ax (A1, A2) and Bx (B1, B2) pins in a high-impedance state, which significantly reduces the quiescent current consumption. The TCA39416 is compatible with 12.5 MHz I3C speeds and also supports higher speed SPI applications with two devices. It also enables bidirectional voltage level translation for traditional I2C-bus/SMBus applications under normal I 2C and SMBus configurations. The TCA39416 features internal 10-k Ω pull-up resistors on Ax and Bx that act as high-keeper and are enabled based on respective V CC voltage when bus is high.

7 Detailed Description
7.1 Overview
The TCA39416 device is a directionless voltage-level translator specifically designed for translating logic voltage levels. The device is MIPI I3C v1.1.1 compatible supporting data rates up to 12.5 Mbps in I3C Single Data Rate (SDR) mode and 25 Mbps in I3C High Data Rate (HDR-DDR) mode. Like SDR Mode, HDR-DDR Mode uses SCL as a clock; however unlike SDR, data is sampled on both edges of clock SCL effectively doubling the data rate achieving 25 Mbps. The A and B ports are able to accept I/O voltages ranging from 0.72 V to 1.98 V. VCCA must be ≤ VCCB to ensure proper operation. The device is a pass-gate architecture with edge-rate accelerators (one-shots) to improve the overall data rate and supports both high speed push-pull and low speed open-drain operation. MIPI I3C specification requires dynamic pull-up control to switch between “strong pull-up” and “weak pull-up” to optimize open-drain and push-pull timing requirements. In TCA39416, the internal 10-k Ω pull-up resistors on Ax and Bx pins are enabled based on respective VCC voltage and OE input and act as High-Keeper when the bus is high. When OE is low, the TCA39416 is disabled, the one shots and internal pull ups are also disabled.
7.2 Functional Block Diagram
7.3 Feature Description
7.3.1 Architecture
The TCA39416 architecture (see Figure 7-1) is an auto-direction-sensing based translator that does not require a direction-control signal to control the direction of data flow from A to B or from B to A. www.ti.com TCA39416 SCPS282B – DECEMBER 2022 – REVISED NOVEMBER 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 11 Product Folder Links: TCA39416
Figure 7-1. Architecture of a TCA39416 Cell These two bidirectional channels support both directions of data flow without a direction-control signal. By properly biasing the gate of the pass-FET, the FET can turn on (low RDSON), when either side input voltage drops to ~ 1 voltage threshold below the lowest of the two supplies. The TCA39416 is part of the TI "Switch" type voltage translator family and employs key circuits to enable this voltage translation: 1. An N-channel pass-gate transistor topology that ties the A-port to the B-port. 2. Output rise time accelerator circuitry to detect and accelerate rising edges on the A or B ports 3. Output fall time accelerator circuitry to detect and accelerate falling edges on the A or B ports For bidirectional voltage translation, pull up resistors are included on the device for dc current sourcing capability. The V GATE gate bias of the N-channel pass transistor is set to the lower supply voltage and can be represented with VCCA. The rise and fall time accelerator (RTA and FTA, respectively) circuitry speeds up the output slew rate by monitoring the input edge for transitions, helping maintain the data rate through the device. During a low-to-high signal rising edge, the rise time accelerator (RTA) circuit turns on to increase the current drive capability of the driver. This edge-rate acceleration provides high ac drive by bypassing the internal 10-k Ω pull up resistors during the low-to-high transition to speed up the signal. The output resistance of the driver is decreased to approximately 150 Ω during this acceleration phase. During a high-to-low signal falling edge, the fall time accelerator (FTA) turns on to increase the current drive capability of the driver, similar to the rise time accelerator. This helps reduce the fall time for large capacitive loads. For light capacitive loads, the fall time accelerator will not enable.
7.3.2 Enable and Disable
The TCA39416 has an OE input that is used to disable the device by setting OE low, which prevents any signals from propagating across the device. This pin is referenced to the VCCA supply. The rise and fall time accelerators and the internal pull-up resistors are also disabled. The disable time (t dis) indicates the delay between the time when OE goes low and when the outputs are disabled (Hi-Z). The enable time (t en) indicates the amount of time the user must allow for the one-shot circuitry to become operational after OE is taken high.

7.3.3 Pull up resistors on I/O Lines
I3C Controllers manage an active (such as, dynamic) pull-up resistance on SDA, which they can enable and disable as the bus transitions between open drain and push-pull mode. The continuous DC current sourcing or sinking capability is determined by the external system-level open-drain or push-pull drivers that are interfaced to the TCA39416 I/O pins. In TCA39416, each A-port I/O has an internal 10-kΩ pull up resistor to VCCA, and each B-port I/O has an internal 10-kΩ pull up resistor to VCCB. The internal pull ups of the TCA39416 are controlled by their respective supplies. The resistors have back-biasing protection, so that if a supply is off, the current cannot flow through the resistors back into the supply. When both A and B side supply is above V UVLO_RISE and OE is high, the pull up resistors are enabled when the bus is high.
7.3.4 Input Driver Requirements
The continuous dc-current "sinking" capability is determined by the external system-level open-drain (or push- pull) drivers that are interfaced to the TCA39416 I/O pins. Since the high bandwidth of these bidirectional I/O circuits is used to facilitate this fast change from an input to an output and an output to an input, they have a modest dc-current "sourcing" capability of hundreds of micro-Amps, as determined by the internal 10-k Ω pullup resistors. The fall time (t fA, tfB) of a signal depends on the edge-rate and output impedance of the external device driving TCA39416 data I/Os, as well as the capacitive loading on the data lines. Similarly, the tPHL and max data rates also depend on the output impedance of the external driver. The values for tfA, tfB, tPHL, and maximum data rates in the data sheet assume that the output impedance of the external driver is below VOL on both sides.
7.4 Device Functional Modes
The TCA39416 device has two functional modes, enabled and disabled. To disable the device, set the OE input low, which disables the rise time and fall time accelerators, and prevents signals from propagating across the channels. The internal pull up resistors are also affected by the OE input and are disabled when OE input is low. Setting the OE input high enables the device. The internal pull-up resistors act has High-Keeper and are enabled based on respective VCC voltage when bus is high. Table 7-1 provides functional description for TCA39416. Table 7-1.

8 Application and Implementation
Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality.
8.1 Application Information
The TCA39416 can be used to bridge the digital-switching compatibility gap between two voltage nodes to successfully interface logic threshold levels found in electronic systems. It should be used in a point-to-point topology for interfacing devices or systems operating at different interface voltages with one another. The primary target application use is for interfacing with I3C push-pull drivers or open-drain drivers on the data I/Os such as I2C or SMBus, where the data is bidirectional and no control signal is available.

8.2.2 Detailed Design Procedure
To begin the design process, determine the following:
- Input voltage range – Use the supply voltage of the device that is driving the TCA39416 device to determine the input voltage range. For a valid logic high, the value must exceed the VIH of the input port. For a valid logic low, the value must be less than the VIL of the input port.

Figure 8-2. Level-Translation of a 12.5-MHz Signal
8.3 Power Supply Recommendations
The TCA39416 has no supply restrictions outside of the 0.72 V to 1.98 V range. V CCA must be ≤ VCCB for proper operation. The sequencing of each power supply does not damage the device during the power up operation, so either power supply can be ramped up first. The output-enable (OE) input circuit is designed so that when the (OE) input is low, the outputs are disabled. No signals may propagate the rise time and fall time accelerators, and the internal pull up resistors are disabled. To make sure the signals do not pass through during power up or power down, the OE input pin must be tied to GND through a pull down resistor. The OE input pin should not be enabled until VCCA and VCCB are fully ramped and stable. If OE is tied to V CCA, this is OK, but might result in a glitch on the bus during power up depending on the capacitive load and ramp rates. The minimum value of the pull down resistor to ground is determined by the current-sourcing capability of the driver. www.ti.com TCA39416 SCPS282B – DECEMBER 2022 – REVISED NOVEMBER 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 15 Product Folder Links: TCA39416

Bypass capacitors should be used on power supplies and should be placed as close as possible to the VCCA, VCCB pin, and GND pin. 2. Short trace lengths should be used to avoid excessive loading. 3. Keep Ax and Bx lengths close to prevent skewing the signals. 4. PCB signal trace-lengths must be kept short enough so that the round-trip delay of any reflection is less than the one-shot duration, approximately < 20 ns. Making sure that any reflection encounters low impedance at the source driver.

9.5 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
