Overview
The SN74AVC1T45 is a single-bit noninverting bus transceiver produced by Texas Instruments. This device is designed for asynchronous communication between two data buses and operates with two separate configurable power-supply rails. The SN74AVC1T45 is functional with VCCA/VCCB as low as 1.2V and supports universal low-voltage, bidirectional translation between various voltage nodes (1.2V, 1.5V, 1.8V, 2.5V, and 3.3V).
