EVM Description and Configuration
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.

The TXS0202 EVM was created to allow simplified evaluation and prototyping without the need for full
board development. This EVM provides peripheral header style pads for probing and signal connection to
each device pin. Headers are labeled with the corresponding pin number. The pin number assignments
are given in the following table.
