HT12E & HT12D Encoder Decoder Pair IC

Description

The HT12E (Encoder) and HT12D (Decoder) are a pair of ICs designed for remote control systems. These ICs are commonly used in wireless communication applications such as RF remote controls, security systems, and home automation. The HT12E encodes 12-bit data (8 address bits and 4 data bits) into a serial format for transmission, while the HT12D decodes the received serial data back into 12-bit parallel data.
