DESCRIPTION

The TXS0202 is a 2-bit voltage level translator optimized for use in Interchip USB (IC-USB) applications. VCCA

and VCCB can each operate over the full range of 1.65 V to 3.6 V. The device has been designed to maintain

cross-over skew to be less than 1 ns. The device has integrated pull-ups and pull-down resistors to aid in the

protocol communication between a host and a peripheral. The translator is a buffered auto-direction sensing type

translator. When the output-enable (OE) input is low, all outputs are placed in the high-impedance state.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,

preventing damaging current backflow through the device when it is powered down. 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.
