The ROM-WT138LM(N) series are remote control receiver modules. Pin diode and receiver IC are assembled on one module. Small- sized, light-weight, and low current consumption. modules have been achieved by using resin mold. The demodulated output signal can directly be decoded by a microprocessor.

The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses.

Features:

•  Supply Voltage Range: 2.7V to 6 V
• TTL and CMOS compatibility
•  Photo detector and preamplifier in one package.
•  Internal filter for PCM frequency
• Open collector output (built-in Pull-up resistor(40 ㏀ ))
• Output active low
•  Enhanced Immunity against all kinds of disturbance light
•  No occurrence of disturbance pulses at output pin within nominal conditions.

 Short settling time after power On.( below 1msec)
