Octal Bus T ransceiver
The SN74LS245 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
