SN74LS245
Octal Bus Transceiver
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
