description
These 10-bit bus 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 (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 SN54BCT29862B is characterized for
operation over the full military temperature range
of − 55°C to 125°C. The SN74BCT29862B is
characterized for operation from 0°C to 70°C.
