Octal Bus Transceivers

These octal bus transceivers are designed for asynchronous two-way communication between

data buses. The devices transmit data from the A bus to the B bus or from the B bus to the A bus

depending upon the level at the direction control (DIR) input. The enable input (G) can be used to

disable the device so the buses are effectively isolated.
