HT12A Description

Short technical summary and product information.

The HOLTEK HT12A is a CMOS LSI encoder designed for remote control applications. It is part of the 212 series and is capable of encoding information with 8 address bits and 4 data bits. The device operates within a voltage range of 2.4V to 5V, making it suitable for various low-power applications.

 

The HT12A features a DATA trigger and includes a 38kHz carrier for infrared transmission systems. It requires minimal external components, including a 455kHz resonator for its built-in oscillator. The data code has a positive polarity. The encoder is available in 18-pin DIP and 20-pin SOP packages.

 

This encoder is designed to pair with Holtek's 212 series of decoders. Its features make it suitable for applications such as burglar alarm systems, smoke and fire alarms, garage door controllers, car door controllers, car alarm systems, security systems, and cordless telephones.
