Description

The HT12E is encoder of CMOS LSIs for remote control system applications. It is capable of encoding information which consists of N address bits and 12-N data bits. 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 series of encoders. The HT12A additionally provides a 38kHz carrier for infrared systems. HT12E Features • Operating voltage 2.4V~12V• Low power and high noise immunity CMOS technology• Low standby current: 0.1_A (typ.) at VDD=5V• HT12A with a 38kHz carrier for infrared transmission medium• Minimum transmission word Four words for the HT12E• Built-in oscillator needs only 5% resistor• Data code has positive polarity• Minimal external components• Pair with Holtek_s 212 series of decoders• 18-pin DIP, 20-pin SOP package HT12E Applications • 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
