DESCRIPTION/ORDERING INFORMATION
This 2-bit unidirectional translator uses two separate configurable power-supply rails. The A port is designed to
track V_CCA. V_CCA accepts any supply voltage from 0.9 V to 3.6 V. The B port is designed to track V_CCB. V_CCB
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 V_CCA. This device is fully specified for partial-power-down applications using Ioff. The I_off
circuitry disables the outputs, preventing damaging current backflow through the device when it is powered
down.
