The SN74AVCH1T45 is a single-bit noninverting bus transceiver that uses two separate configurable power-supply rails. The A port is designed to track VCCA, which accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB, which accepts any supply voltage from 1.2V to 3.6V. This feature allows for universal low-voltage, bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V voltage nodes.

The SN74AVCH1T45 is designed for asynchronous communication between two data buses. The device transmits data from either the A bus to the B bus, or from the B bus to the A bus, depending upon the logic level at the direction-control (DIR) input.

The SN74AVCH1T45 is designed so that the DIR input is referenced to VCCA.
