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. • Hysteresis Inputs to Improve Noise Immunity • 2-Way Asynchronous Data Bus Communication • Input Diodes Limit High-Speed Termination Effects • ESD > 3500 Volts LOGIC A.
