3 Description
Voltage-level translators address the challenges posed by simultaneous use of different supply-voltage levels on the same circuit board. This 4-bit non- inverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track V CCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. V CCA should not exceed VCCB. When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. The TXB0104 is designed so that the OE input circuit is supplied by VCCA. This device is fully specified for partial-power-down applications using I off. The I off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

8 Detailed Description
8.1 Overview
The TXB0104 device is a 4-bit, bi-directional voltage-level translator specifically designed for translating logic voltage levels. The A port is able to accept I/O voltages ranging from 1.2 V to 3.6 V, while the B port can accept I/O voltages from 1.65 V to 5.5 V. The device is a buffered architecture with edge-rate accelerators (one-shots) to improve the overall data rate. This device can only translate push-pull CMOS logic outputs. If for open-drain signal translation, please refer to TI’s TXS010X products.
8.2 Functional Block Diagram
8.3 Feature Description
8.3.1 Architecture
The TXB0104 architecture (see Section 8.2) does not require a direction-control signal to control the direction of data flow from A to B or from B to A. In a DC state, the output drivers of the TXB0104 can maintain a high or low, but are designed to be weak, so that they can be overdriven by an external driver when data on the bus starts flowing the opposite direction. The output one-shots detect rising or falling edges on the A or B ports. During a rising edge, the one-shot turns on the PMOS transistors (T1, T3) for a short duration, which speeds up the low-to-high transition. Similarly, during a falling edge, the one-shot turns on the NMOS transistors (T2, T4) for a short duration which speeds up www.ti.com TXB0104-Q1 SCES727B – JUNE 2008 – REVISED JUNE 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 11 Product Folder Links: TXB0104-Q1
the high-to-low transition. The typical output impedance during output transition is 70 Ω at VCCO = 1.2 V to 1.8 V, 50 Ω at VCCO = 1.8 V to 3.3 V, and 40 Ω at VCCO = 3.3 V to 5 V. A B VCCA VCCB One Shot One Shot One Shot One Shot Figure 8-1. Architecture of TXB0104 I/O Cell
8.3.2 Input Driver Requirements
Typical IIN vs V IN characteristics of the TXB0104 are shown in Figure 8-2 . For proper operation, the device driving the data I/Os of the TXB0104 must have drive strength of at least ±2 mA. IIN VIN VT /4 k ±(VD ± VT)/4 k Figure 8-2. Typical IIN vs VIN Curve
8.3.3 Output Load Considerations
TI recommends careful PCB layout practices with short PCB trace lengths to avoid excessive capacitive loading and to ensure that proper one shot (O.S.) triggering takes place. PCB signal trace-lengths should be kept short enough such that the round trip delay of any reflection is less than the one-shot duration. This improves signal integrity by ensuring that any reflection sees a low impedance at the driver. The O.S. circuits have been designed to stay on for approximately 10 ns. The maximum capacitance of the lumped load that can be driven also depends directly on the one-shot duration. With very heavy capacitive loads, the one-shot can time-out before the signal is driven fully to the positive rail. The O.S. duration has been set to best optimize trade-offs between dynamic I CC, load driving capability, and maximum bit-rate considerations. Both PCB trace length and connectors add to the capacitance that the TXB0104 output sees, so it is recommended that this lumped-load TXB0104-Q1 SCES727B – JUNE 2008 – REVISED JUNE 2023 www.ti.com

capacitance be considered to avoid O.S. retriggering, bus contention, output signal oscillations, or other adverse system-level affects.
8.3.4 Enable and Disable
The TXB0104 has an OE input that is used to disable the device by setting OE = low, which places all I/Os in the high-impedance (Hi-Z) state. The disable time (t dis) indicates the delay between when OE goes low and when the outputs actually get 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.
8.3.5 Pullup or Pulldown Resistors on I/O Lines
The TXB0104 is designed to drive capacitive loads of up to 70 pF. The output drivers of the TXB0104 have low DC drive strength. If pullup or pulldown resistors are connected externally to the data I/Os, their values must be kept higher than 50 kΩ to ensure that they do not contend with the output drivers of the TXB0104. For the same reason, the TXB0104 should not be used in applications such as I 2C or 1-Wire where an open-drain driver is connected on the bidirectional data I/O. For these applications, use a device from the TI TXS01xx series of level translators.

The TXB0104 device has two functional modes, enabled and disabled. To disable the device, set the OE input to low, which places all I/Os in a high impedance state. Setting the OE input to high will enable the device. www.ti.com TXB0104-Q1 SCES727B – JUNE 2008 – REVISED JUNE 2023 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 13 Product Folder Links: TXB0104-Q1
9 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. Customers should validate and test their design implementation to confirm system functionality.
9.1 Application Information
The TXB0104 can be used in level-translation applications for interfacing devices or systems operating at different interface voltages with one another. It can only translate push-pull CMOS logic outputs. If for open- drain signal translation, please refer to TI TXS010X products. Any external pulldown or pullup resistors are recommended larger than 50 kΩ.
9.2 Typical Application
Figure 9-1. Typical Application Schematic
9.2.1 Design Requirements
For this design example, use the parameters listed in Table 9-1. And make sure the VCCA ≤VCCB. Table 9-1. Design Parameters DESIGN PARAMETERS EXAMPLE VALUE Input voltage range 1.2 V to 3.6 V Output voltage range 1.65 V to 5.5 V
9.2.2 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 TXB0104 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.
- Output voltage range - Use the supply voltage of the device that the TXB0104 device is driving to determine the output voltage range. - It is not recommended to have the external pullup or pulldown resistors. If mandatory, it is recommended the value should be larger than 50 kΩ.
- An external pulldown or pullup resistor decreases the output V OH and V OL. Use the below equations to draft estimate the VOH and VOL as a result of an external pulldown and pullup resistor. TXB0104-Q1 SCES727B – JUNE 2008 – REVISED JUNE 2023 www.ti.com

VOH = VCCx × RPD / (RPD + 4.5 kΩ) (1) VOL = VCCx × 4.5 kΩ / (RPU + 4.5 kΩ) (2) where
- VCCx is the output port supply voltage on either VCCA or VCCB
- RPD is the value of the external pull down resistor
- RPU is the value of the external pull up resistor
- 4.5 kΩ is the counting the variation of the serial resistor 4 kΩ in the I/O line

10 Power Supply Recommendations
During operation, ensure that V CCA ≤ VCCB at all times. During power-up sequencing, V CCA ≥ VCCB does not damage the device, so any power supply can be ramped up first. The TXB0104 has circuitry that disables all output ports when either V CC is switched off (V CCA/B = 0 V). The output-enable (OE) input circuit is designed so that it is supplied by VCCA and when the (OE) input is low, all outputs are placed in the high-impedance state. To ensure the high-impedance state of the outputs during power up or power down, the OE input pin must be tied to GND through a pulldown resistor and must not be enabled until V CCA and VCCB are fully ramped and stable. The minimum value of the pulldown resistor to ground is determined by the current-sourcing capability of the driver.
11 Layout
11.1 Layout Guidelines
To ensure reliability of the device, following common printed-circuit board layout guidelines are recommended:
- Bypass capacitors should be used on power supplies. And should be placed as close as possible to the VCCA, VCCB pin, and GND pin
- Short trace-lengths should be used to avoid excessive loading.
- 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 10 ns, ensuring that any reflection encounters low impedance at the source driver.
