DESCRIPTION
This 2-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 1.65V to 3.6V while it tracks the VCCA
supply, and the B ports supporting operating voltages from 2.3V to
5.5V 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 1.8V, 2.5V, 3.3V, and 5V 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 pull-down resistor; the
minimum value of the resistor is determined by the current-sourcing
capability of the driver.
