The MN6011 is designed as one kind of multi-function infrared remote control transmitter integrated circuit, and it can be used in the VCR. The internal circuit is composed of the oscilation circuit, the key input control circuit, the tuning generator, the pulse generator, the modulation circuit, the 11-bit self-locking shift register and the unified data generator. Features The CMOS technology very large scale integrated circuit (VLSI)The typical value of the power supply voltage is 3V. Function description It can set 64 conventional keys and 32 unified keys freely.All the keys can output the repetitive pulse sequence.When there is no key operation, the oscillation circuit will stop working.The external, LC circuit, ceramic filters and crystal oscillator can produce the 440kHz oscillating wave.The LED display.The output pulse is composed of the 5-bit conventional code, the 6-bit data code, the 5-bit conventional RP code and the 6-bit data RP code.
