Overview
NTE1757 Integrated Circuit Remote Control Receiver 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 communication with microprocessors and computers.
Features; D 5 Open Drain Outputs with Enable D Handshake or Interrupt Microprocessor and Computer Interface Signals D On–Chip Oscillator D 6 Control Lines to Program Output Response D 3 Selectable Output Modes Absolute Maximum Ratings: VDD Supply and All Inputs wrt, VSS .
