description
This 9-bit transceiver is designed for
asynchronous two-way communication 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.
The SN74ALS29863 is characterized
operation from 0°C to 70°C.
