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 for

operation from 0°C to 70°C.
