The TC9149P/TC9150F is designed as the infrared remote control receiving CMOS large-scale circuit that can be used in the video recorder and TV set applications. The internal circuit is composed of the input pulse register, the input pulse counter, the shift register, the code detection circuit, the oscillator, the counter, the locking circuit, the error identification circuit and the output buffer circuit.
Features
The matching model is TC9148P.The TC9149P uses the 16-pin dual-row DIP plastic package.The TC9150P uses the 24-pin dual-row DIP plastic package.
Function declaration
The oscillation frequency of the oscillator is decided by the external resistance and capacitance.The signal adds to the signal receiving input port pin-2 after it is amplified and detected by the circuit.
