Description

HT12E Encoder IC

HT12E is a 212 series encoder IC (Integrated Circuit) for remote control applications. It is commonly used for radio frequency (RF) applications. By using the paired HT12E encoder and HT12D decoder we can easily transmit and receive 12 bits of parallel data serially. HT12E simply converts 12 bits parallel data into serial output which can be transmitted through an RF transmitter. These 12 bits parallel data are divided into 8 address bits and 4 data bits. By using these address pins, we can provide 8 bits security code for data transmission and multiple receivers may be addressed using the same transmitter.
