MC3373
Remote Control
Amplifier/Detector
The MC3373 is intended for application in infrared remote controls. It
provides the high gain and pulse shaping needed to couple the signal from
an IR receiver diode to the tuning control system logic.
• High Gain Pre–Amp
• Envelope Detector for PCM Demodulation
• Simple Interface to Microcomputer Remote Control Decoder
• Use with Tuned Circuit for Narrow Bandwidth, Lower Noise Operation
• Minimum External Components
• Wide Operating Supply Voltage Range
• Low Current Drain
• Improved Retrofit for NEC Part No. µPC1373
• MC14497 Recommended IR Transmitter
• MLED81 Complementary Emitter
• MRD821 Complementary Detector Diode
