DESCRIPTION/ORDERING INFORMATION

This 2-bit non-inverting translator uses two separate configurable power-supply rails. The A port is designed to

track V_CCA. V_CCAaccepts any supply voltage from 0.9 V to 3.6 V. The B port is designed to track V_CCB. V_CCB

accepts any supply voltage from 0.9 V to 3.6 V. This allows for low-voltage bidirectional translation between 1-V,

1.2-V, 1.5-V, 1.8-V, 2.5-V and 3.3-V voltage nodes. For the TXS0302, 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 pull-down resistor; the minimum value of the resistor is

determined by the current-sourcing capability of the driver. The TXS0302 is designed so that the OE input circuit

is supplied by V_CCA. This device is fully specified for partial-power-down applications using I_off. The I_offcircuitry

disables the outputs, preventing damaging current backflow through the device when it is powered down. For

typical application circuitry, refer to Figure 1.
