These 9-bit transceivers are designed for
asynchronous communication between data
buses. The control-function implementation
allows for maximum flexibility in timing.
SN54BCT29863B . . . FK PACKAGE
(TOP VIEW)
These devices allow data transmission from the A
bus to the B bus or from the B bus to the A bus,
depending upon the logic levels at the
output-enable (OEBA and OEAB) inputs.

The outputs are in the high-impedance state
during power-up and power-down conditions. The
outputs remain in the high-impedance state while
the device is powered down.
The SN54BCT29863B is characterized for
operation over the full military temperature range
of –55°C to 125°C. The SN74BCT29863B is
characterized for operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The negative input voltage ratings may be exceeded if the input current rating is observed.
