Overview
The SN74LVTH16245ADGGR is a 16-bit bus transceiver with 3-state outputs, manufactured by Texas Instruments. This device is part of the Advanced Bus Technology (ABT) family and is designed for asynchronous communication between data buses. It operates from 1.65 V to 3.6 V, making it versatile for various voltage environments. The device can be used as two 8-bit transceivers or one 16-bit transceiver, allowing data transmission from the A bus to the B bus or vice versa, controlled by the direction-control (DIR) input. The output-enable (OE) input allows the device to be disabled, effectively isolating the buses.
