These 9-bit transceivers are designed for asynchronous communication between data buses. The control-function implementation allows for maximum flexibility in timing.
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 (
and
) 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.
