NTE1757 Datasheet | NTE Electronics

Description : The NTE1757 is an MOS/LSI integrated circuit in an 18- Lead DIP tpye package designed for use as a receiver of remote control signals generated by a transmitter circuit, using PPM (Pulse Position Modulation) encoding technique. The receiver has 5 digital outputs whose response to PPM codes may be programmed by six control lines. It has a handshake interface which provides munication with microprocessors and puters.
