Octal 3-State Noninverting Bus Transceiver
These octal bus transceiver are designed for asynchronous two-way communication between data buses. The control function implementation minimized external timing requirements.
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 level at the directional control (DIR) input. The enable input(E) can be used to disable the device so that the buses are effectively isolated.
