description

The ′BCT640 bus transceiver is designed for

asynchronous communication between data

buses. These 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 output-enable (OE) input can be

used to disable the device so that the buses are

effectively isolated.
