SN74ALS29863 Overview
This 9-bit transceiver is designed for asynchronous two-way munication between data buses. The control-function implementation allows for maximum flexibility in timing. This device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic levels at the output-enable (OEAB1, OEAB2, OEBA1, and OEBA2) inputs.
