Overview
The SN74AVC16245DGGR is a 16-bit bus transceiver with 3-state outputs, manufactured by Texas Instruments. This device is part of the Texas Instruments Widebus™ family and is designed for asynchronous communication between data buses. It can operate as two 8-bit transceivers or one 16-bit transceiver, allowing data transmission from the A bus to the B bus or vice versa, based on the logic level at the direction-control (DIR) input. The device supports partial-power-down mode operation and is characterized for operation from –40°C to 85°C.
