The M50U5P/AF/BP/CP are designed as the infrared remote control launch circuit that can be used in the video tape recorder, TV and stereo 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 M50115P, M50115AP, M50115BP, M50115CP is the identification code. Features It uses the single power operating mode, the power voltage is 2.2-8V;It uses the 18-pin dual-row DIP plastic package;When the keyboard button is not pressed, the oscillator will stop oscillating to reduce the power consumption;the pulse duty cycle is small;It has less external components, the SNR is high, the great anti-interference ability.
