The HT12E Encoder ICs are series of CMOS LSIs for Remote Control system applications. They are capable of Encoding 12 bit of information which consists of 8 address bits and 4 data bits. Each address and data input is externally programmable or fed in using switches.

HT12E  Specifications:

• Operating Voltage : 2.4V ~ 12V
• Easy Interface with and RF or an Infrared transmission medium
• Secure and robust protocol
• 18-pin DIP (Dual Inline Package) & 20 pin SOP (Small Outline Package) 
• Low Standby Current : 0.1uA (typ.) at VDD=5V
• Low Power and High Noise Immunity
