Datasheet Summary
Octal Bus Transceiver
The SN74LS245 is an Octal Bus Transmitter/Receiver designed for 8-line asynchronous 2-way data munication 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 munication
- Input Diodes Limit High-Speed Termination Effects
- ESD > 3500 Volts
