The MC145026 is designed as one kind of general infrared ray, ultrasonic or RF remote control launch coding circuit. The internal circuit is composed of the oscillator, the enable circuit, the frequency divider, the data selection and buffer circuit, the ternary detection circuit, the annular counter and the coding 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%.
