The SAA3027 is designed as one kind of general infrared remote control launch circuit. The internal circuit is composed of the oscillator, the test mode circuit, the mode selection circuit, the keyboard encoder, the control unit circuit, the decoder, the keyboard driver decoder, the instruction and system address latch and the frequency divider. Features Low voltage power supply, the power consumption is very small,It uses the dual-phase launch technology, the launch time is short,The input protection,The simple test mode,The oscillator is connected with the LC frequency stabilizer, there is no need of the crystal oscillator,Every button of the keyboard is the single-pole switch,28-pin dual-row DIP plastic package.
