This 2-bit unidirectional translator
uses two separate configurable power-supply rails. The A port is designed to track
VCCA. VCCA accepts any supply voltage from 0.9 V to 3.6 V.
The B port is designed to track VCCB. VCCB accepts any supply
voltage from 0.9 V to 3.6 V. This allows for low-voltage translation between 0.9-V,
1.2-V, 1.5-V, 1.8-V, 2.5-V and 3.6-V voltage nodes. For the SN74AVC2T244, when the
output-enable ( OE) input is high, all outputs are placed in
the high-impedance state. The SN74AVC2T244 is designed so that the
OE input circuit is referenced to VCCA. 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.
