The SAAl250 is designed as one kind of infrared remote control launch circuit that can be used in the TVs. The internal circuit is composed of the program control circuit, the RC oscillator, the FAS trigger circuit, the clock generator, the row and column input circuit, the decoder, the input calibration circuit, the address register, the parallel/serial conversion circuit, the monitoring circuit, the mode selection decoder and the output stage.etc. Features It uses the CMOS technology,The 24-pin dual-row DIP plastic package,The matching model is TBA2800. The frequency of the RC oscillator is decided by the pin-3's external resistor R1 and pin-2's external resistor C, the function of it is to supply the reference oscillation signal to the clock generator.
