AT156R AT156R Photo Module for PCM Remote Control Systems Types & Carrier frequency Type fo Type fo AT133R AT133R 33 kHz AT140R AT140R 40 kHz AT136R AT136R 36 kHz AT156R AT156R 56 kHz AT138R AT138R 38 kHz Description The AT1.R series are miniaturized receiver for infrared remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the reliable function even in disturbed ambient and protects against uncontrolled output pulses. Features Special Features Internal filter for PCM frequency Enhanced immunity against all kinds of disturbance light TTL and CMOS compatibility No occurrence of disturbance pulses at Output active low the output.
