Encoder and Decoder ICs (HT12E – HT12D)

The HT12E encoder is designed for remote control system applications. It will interface to RF transmitter modules to create a secure single or multiple channel RF remote control transmitter. The oscillator is configured simply with the addition of a resistor. It is capable of encoding information which consists of N address bits and 12-N data bits. Each address/data input can be set to one of the two logic states.
The programmed addresses/data are transmitted together with the header bits via an RF transmission medium upon receipt of a trigger signal.
The HT12D decoder is a CMOS LSI for remote control system applications. It will interface to RF receiver modules to create a secure single or multiple channel RF remote control receiver. The decoder receives serial addresses and data from a programmed encoder that are transmitted by a carrier using an RF or an IR transmission medium. The decoder compares the serial input data three times continuously with its local addresses. If no error or unmatched codes are found, the input data codes are decoded and then transferred to the output pins.
The VT pin also goes high to indicate a valid transmission. The HT12D decoder is capable of decoding information that consist of N bits of address and 12-N bits of data.  The HT12D is arranged to provide 8 address bits and 4 data bits.
