Suitable Data Format

The CLT138TM(N) series are remote control receivermodules. Pin diode and receiver IC are assembled onone module. Small- sized, light-weight, and low currentconsumption. modules have been achieved by using resinmold. The demodulated output signal can directly bedecoded by a microprocessor.The main benefit is the reliable function even in disturbedambient and the protection against uncontrolled output pulses.

Description

R-C filter recommended to suppress power supply disturbances.R-C filter should be connected closely between VCC pin and GND pin.
