DM54LS245 - TRI-STATE Octal Bus Transceiver
These octal bus transceivers are designed for asynchronous two-way communication between data buses The control function implementation minimizes external timing requirements The device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic level
