Overview
The SN74LVC16245ADGGR is a 16-bit bus transceiver with 3-state outputs, designed and manufactured by Texas Instruments. This device is part of the Widebus™ family and is optimized for asynchronous communication between data buses. It operates over a wide voltage range from 1.65 V to 3.6 V, making it versatile for various applications. The SN74LVC16245A can be used as two 8-bit transceivers or one 16-bit transceiver, allowing data transmission between the A and B buses based on the direction-control (DIR) input. The output-enable (OE) input allows the device to be disabled, effectively isolating the buses.
