Features

Bi-directional interface between any 2 levels from 1.1V to 3.6V Fully configurable: Inputs track V CC level Non-preferential power-up sequencing; either V CC may be powered-up first Outputs remain in 3-STATE until active V CC level is reached Outputs switch to 3-STATE if either V CC is at GND Power off protection Bushold on data inputs eliminates the need for external pull-up/pull-down resistors Control input (T/R) levels are referenced to V CCA voltage Packaged in the MicroPak 6 (1.0mm x 1.45mm) ESD protections exceeds: – 4kV HBM ESD (per JESD22-A114 & Mil Std 883e 3015.7) – 8kV HBM I/O to GND ESD (per JESD22-A114 & Mil Std 883e 3015.7) – 1kV CDM ESD (per ESD STM 5.3) – 200V MM ESD (per JESD22-A115 & ESD STM5.2) General Description The FXLH1T45 is a single bit configurable dual-voltage supply translator designed for both uni-directional and bi-directional voltage translation between two logic lev- els. The device allows translation between voltages as high as 3.6V to as low as 1.1V. The A port tracks the V CCA level, and the B port tracks the V CCB level. This allows for bi-directional voltage translation over a variety The device remains in 3-STATE until both V CC s reach active levels allowing either V CC to be powered-up first. Internal power down control circuits place the device in 3-STATE if either V CC is removed. The Transmit/Receive (T/R) input determines the direc- tion of data flow through the device. The FXLH1T45 is designed so that the control pin (T/R ) is supplied by V CCA

This benefit derives from the chip design. When either V CC is at 0V, outputs are in a HIGH-Impedance state. To ensure that bus contention, excessive currents, or oscillations do not occur, a proper power-up sequence is recommended. The recommended power-up sequence is the following: 1. Apply power to either V CC 2. Apply power to the T/R input (Logic HIGH for A-to-B operation; Logic LOW for B-to-A operation) and to the respective data inputs (A Port or B Port). This may occur at the same time as Step 1. 3. Apply power to other V CC The recommended power-down sequence is the follow- ing: 1. Remove power from either V CC 2. Remove power from other V CC Pin Number Terminal Name CCA

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Recommended Operating Conditions (2) The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not recommend exceeding them or designing to absolute maximum ratings. Notes: 1. I O Absolute Maximum Rating must be observed. 2. All unused inputs and I/O pins must be held at V CCI or GND.

The enable time, tPZH or tPZL, is the time for the FXLH1T45 to return to active operation after a direction change. The enable time specifies the worst-case delay from the time the T/R pin is switched until a valid output signal is expected. For example, to change direction to B-to-A operation, the T/R pin is switched from HIGH-to-LOW. The enable time for this case is found by adding the disable time for T/R to B to the propagation delay for B to A. The formulas for calculating enable times are the following: tPZH (T/R to A) = tPLZ (T/R to B) + tPLH (B to A) tPZL (T/R to A) = tPHZ (T/R to B) + tPHL (B to A) tPZH (T/R to B) = tPLZ (T/R to A) + tPLH (A to B) tPZL (T/R to B) = tPHZ (T/R to A) + tPHL (A to B) Capacitance Symbol Parameter TA = −40°C to +85°C Units VCCB = 3.0V to 3.6V VCCB = 2.3V to 2.7V VCCB = 1.65V to 1.95V VCCB = 1.4V to 1.6V VCCB = 1.1V to 1.3V tPZH, tPZL Symbol Parameter TA = −40°C to +85°C Units VCCB = 3.0V to 3.6V VCCB = 2.3V to 2.7V VCCB = 1.65V to 1.95V VCCB = 1.4V to 1.6V VCCB = 1.1V to 1.3V tPZH, tPZL Symbol Parameter Conditions TA = +25°C UnitsTypical CIN Input Capacitance Control Pin (T/R)V CCA = VCCB = 3.3V, VI = 0V or VCCA/B 4.0 pF CI/O Input/Output Capacitance An, Bn Ports V CCA = VCCB = 3.3V, VI = 0V or VCCA/B 5.0 pF CPD Power Dissipation Capacitance V CCA = VCCB = 3.3V, VI = 0V or VCC, F = 10MHz 20.0 pF
