HT12E Encoder IC Basics
HT12E is an encoder IC for Remote control applications, commonly used for Radio Frequency (RF) application and it is 2 series IC. We can transmit and receive 12 bits of parallel data serially by using HT12E and HT12D paired. HT12E is a simple Encoder IC that converts serial data to its input through RF to 12 bits parallel data in which there are 4 data bits and 8 address bits. These 8 bits addresses are security code for 4 bits data, means we can provide 8 bits security code for 4 bits data and can use multiple receivers by using the same transmitter.
