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
