Octal Bus Transceivers (non-inverted 3-state outputs)
This octal bus transceivers is 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 that the buses are effectively isolated.
