Overview
The SN74ALVC164245DLR is a 16-bit (dual-octal) noninverting bus transceiver produced by Texas Instruments. This device is part of the Texas Instruments Widebus™ Family and is designed for asynchronous communication between data buses. It features two separate supply rails, allowing for level-shifting between 2.5-V, 3.3-V, and 5-V environments. The control circuitry is powered by VCCA, enabling flexible voltage translation and high-speed data transmission.
