Overview
The SN74ALVC164245DGGR is a 16-bit dual-supply bus transceiver produced by Texas Instruments. This device is designed for asynchronous communication between data buses and features configurable voltage translation and 3-state outputs. It allows for voltage-level translation between different voltage environments, such as from 2.5 V to 3.3 V, or from 3.3 V to 5 V, making it versatile for mixed-voltage systems. The control circuitry is powered by VCCA, and the device supports live insertion and withdrawal (partial-power-down mode).
