HT12D is a decoder integrated circuit that belongs to 212 series of decoders. This series is commonly used in remote control system applications such as burglar alarms, car door controllers, and security systems. It interfaces RF and infrared circuits and is paired with 212 series encoders. The decoder converts serial input into parallel outputs, decoding serial addresses and data received from an RF receiver. It has 8 address bits and 4 data bits, with a built-in oscillator requiring minimal external components.
The HT12D is ideal for applications like burglar alarm systems, garage door controllers, car alarms, and cordless telephones. It ensures secure and reliable decoding of transmitted data for various remote control systems.
