  • SN74AVC2T45  -  This device is a 2-bit bi-directional translator with direction control and 1.2V to 3.6V range

Description

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.

Features
