Product Overview

HT12A/HT12E Series of Encoders DIP IC of CMOS LSIs surprisingly for remote control system applications. They are capable of encoding information which consists of N address bits and thereupon 12-N data bits. So Each address/data input can be set to one of the two logic states. The programmed addresses/data are transmitted together with the header bits via an RF or an infrared transmission medium upon receipt of a trigger signal. The capability to select a TE trigger on the HT12E or a DATA trigger on the HT12A further enhances the application flexibility of the 212 series of encoders. The HT12A additionally provides a 38kHz carrier for infrared systems.

Features of HT12A/HT12E Series of Encoders DIP IC:

  • Operating voltage: specifically 2.4V~5V for the HT12A
  • Low power and high noise immunity CMOS technology
  • Low standby current: 0.1uA (typ.) at VDD=5V
  • HT12A with a 38kHz carrier for infrared transmission medium
  • Minimum transmission word- One word for the HT12A
  • Built-in oscillator needs only 5% resistor
  • Data code has positive polarity
  • Minimal external components
  • Pair with Holtek’s 212 series of decoders

Applications of HT12A/HT12E Series of Encoders DIP IC:

  • Burglar alarm system
  • Smoke and fire alarm system
  • Garage door controllers
  • Car door controllers
  • Car alarm system
  • Security system
  • Cordless telephones
  • Other remote control systems

When working with the HT12A, it’s essential to refer to the manufacturer’s datasheet and application notes for detailed information on its pinout, operating conditions, and recommended usage. The specific requirements for configuring the IC will depend on your project’s needs and subsequently the communication protocol you are implementing.

Keep in mind that there may be variations or improved versions of this IC available in the market, so always check the manufacturer’s latest documentation for the most up-to-date information.
