The ’ABT640 bus transceivers are designed for asynchronous communication between data buses.
These devices transmit inverted data from the A bus to the B bus or from the B bus to the A bus, depending on the level at the directioncontrol (DIR) input.
The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.
