HT12F (HOLTEK)

The HT12F is a remote control Decoder IC for proper operation, a pair of encoder/decoder with the same number of addresses and data format should be chosen. The 12?? encoder receive serial addresses and data from a programmed this series of encoder that is transmitted by a carrier using an RF or an IR transmission medium. It compares the serial input data three times continuously with its local addresses. If no error or unmatched codes is found, the input data code is decoded and then transferred to the output pin. The VT pin also goes high to indicate a valid transmission.
