Octal 3-STATE Transceiver
General Description
This octal bus transceiver is designed for asynchronous
two-way communication between data buses. The inputs
include hysteresis which provides improved noise rejec-
tion. Data is transmitted either from the A bus to the B bus
or from the B bus to the A bus depending on the logic level
of the direction control (DIR) input. The device can be dis-
abled via the enable input (G) which causes the outputs to
enter the high impedance mode so the buses are effec-
tively isolated.
