HT12D Decoder IC for RF Module

HT12D is a decoder IC for remote control applications, commonly in Radiofrequency (RF) wireless applications, and it is 2 series decoders. We can transmit 12 bits of parallel data serially by using HT12E and HT12D. HT12D is a simple Decoder 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, which means we can provide 8 bits security code for 4 bits data and can use multiple receivers by using the same transmitter.
