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.
