NTE NTE1714M Datasheet
NTE1714M
Integrated Circuit
Remote Control Amplifier/Detector
Description:
The NTE1714M is and integrated circuit in an 8–Lead DIP type package designed for use in infrared
remote control applications. It provides the high gain and pulse shaping needed to couple the signal
from an IR receiver diode to the tuning control system logic.
Features:
D High Gain Pre–Amp
D Envelope Detector for PCM Demodulation
D Simple Interface to Microcomputer Remote Control Decoder
D May be Used with Tuned Circuit for Narrow Bandwidth, Lower Noise Operation
D Small Package Size
D Minimum External Components
D Wide Operating Supply Voltage Range
D Low Current Drain
