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 V CCA supply, and the B ports
supporting operating voltages from 2.3 V to 5.5 V while it tracks the
V CCB 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.
