TXS0102DCTR

This two-bit non-inverting translator is a bidirectional
voltage-level translator and can be used to establish
digital switching compatibility between mixed-voltage
systems. It uses two separate configurable powersupply rails, with the A ports supporting operating
voltages from 1.65 V to 3.6 V while it tracks the VCCA
supply, and the B ports supporting operating voltages
from 2.3 V to 5.5 V while it tracks the VCCB supply.
This allows the support of both lower and higher logic
signal levels while providing bidirectional translation
capabilities between any of the 1.8-V, 2.5-V, 3.3-V,
and 5-V voltage nodes.
When the output-enable (OE) input is low, all I/Os
are placed in the high-impedance state, which
significantly reduces the power-supply quiescent
current consumption.
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.
