The device allows 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 SN74BCT29861B is characterized for operation from 0°C to 70°C.
