The M50110P/AP/BP/CP is designed as the 30-function infrared remote control launch circuit that can be used in the video recorder, TV and audio equipment applications. The internal circuit is composed of the keyboard input encoder, the instruction decoder, the oscillator, the timing signal generator, the scanning signal generator, the Coding modulator and the output buffer. The difference between the M50110P, M50110AP, M50110BP, M50110CP is the identification number. Features It uses the single power operating mode, the power voltage is 2.2-8V.The oscillator will stop operating when the keyboard buttons are not pressed to reduce the power consumption.The duty ratio is small to reduce the power consumption of the diode.The external components are few, the SNR is high, the anti-interference ability is strong.It has six input ports and five output ports to form the 6X5 keyboard matrix.The matching models are M5011P/AP/BP/CP, M50116P/AP/BP/CP and M50117P/AP/BP/CP.
