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 power-supply 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.
