SN54/74LS245  
OCTAL BUS TRANSCEIVER  
The SN54/74LS245 is an Octal Bus Transmitter/Receiver designed for  
8-line asynchronous 2-way data communication between data buses.  
Direction Input (DR) controls transmission of Data from bus A to bus B or bus  
B to bus A depending upon its logic level. The Enable input (E) can be used  
to isolate the buses.
