The SC41343 is designed as one kind of infrared, ultrasonic or RF remote control launch coding circuit. The internal circuit is composed of the sequence generator, control logic circuit,4-bit shift register,data extraction circuit and the latch circuit.
Features
It uses the binary or ternary to find the address;The ternary addressing coding has the most kinds;The launch media can be the infrared ray, ultrasonic or the RF;The double information launch can be used to detect the error;The external RC components form the oscillating circuit, so there is no need of the crystal oscillator;The external components has the allowable error range of 5%;The standard B series input and output features;The power voltage is 2.8-10V;The plastic DIP or SOG package;The matching model is SC41342.
