These octal bus transceivers are designed for asynchronous two-way communicaTIon between data buses. The control-funcTIon implementaTIon minimizes external TIming requirements.

The devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE)\ input can be used to disable the device so that the buses are effectively isolated.
