Description
This 2-bit non-inverting translator uses two separate
configurable power-supply rails. The A port is designed
to track VCCA. VCCA accepts any supply voltage from
1.2V to 3.6V. The B port is designed to track VCCB. VCCB
accepts any supply voltage from 1.65V to 5.5V. This
allows for universal low-voltage bidirectional translation
between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and
5V voltage nodes. VCCA should not exceed VCCB.
When the output-enable (OE) input is low, all outputs
are placed in the high-impedance state.
This device is fully specified for partial-power-down
applications using Ioff. The Ioff circuitry disables the
outputs, preventing damaging current backflow through
the device when it is powered down.
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.

(1) The A and B sides of an unused data I/O pair must be held in the same state, i.e., both at VCCI or both at GND.
(2) VCCA must be less than or equal to VCCB and must not exceed 3.6 V.
(3) VCCI is the supply voltage associated with the input port.
