HT12E is an encoder integrated circuit of 212 series of encoders. Paired with 212 series of decoders, it is used in remote control system applications, especially in interfacing RF and infrared circuits. It converts parallel inputs into serial output, encoding 12 bits into 8 address bits and 4 data bits. The transmission enable pin, when triggered, transmits programmed addresses/data via RF or infrared. The encoder begins a 4-word transmission cycle upon enable receipt, repeating until TE is high.
Applications include burglar alarm systems, smoke and fire alarm systems, garage door controllers, car door controllers, car alarm systems, security systems, cordless telephones, and other remote control systems.
