Overview
The SN74ALVC164245DGG is a 16-bit bidirectional 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 device can operate as two 8-bit transceivers or one 16-bit transceiver, enabling data transmission from the A bus to the B bus or vice versa based on the direction-control (DIR) input. The output-enable (OE) input allows the device to be disabled, placing both output ports into a high-impedance state.
