Description

HT12D Decoder IC

HT12D is a 2 series decoder IC (Integrated Circuit) for remote control applications. It is commonly used for radio frequency (RF) wireless applications. By using the paired HT12E encoder and HT12D decoder we can transmit 12 bits of parallel data serially. HT12D simply converts serial data to its input (may be received through RF receiver) to 12 bits parallel data. These 12 bits parallel data are divided into 8 address bits and 4 data bits. Using 8 address bits we can provide 8 bits security code for 4 bits data and can be used to address multiple receivers by using the same transmitter.
