HT12A規(guī)格書詳情
General Description
The 212 encoders are a series of CMOS LSIs for remote control system applications. They are 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.
Features
? Operating voltage
- 2.4V~5V for the HT12A
- 2.4V~12V for the HT12E
? Low power and high noise immunity CMOS technology
? Low standby current: 0.1A (typ.) at VDD=5V
? HT12A with a 38kHz carrier for infrared transmission medium
? Minimum transmission word
- Four words for the HT12E
- One word for the HT12A
? Built-in oscillator needs only 5 resistor
? Data code has positive polarity
? Minimal external components
? Pair with Holteks 212 series of decoders
? 18-pin DIP, 20-pin SOP package
Applications
? Burglar alarm system
? Smoke and fire alarm system
? Garage door controllers
? Car door controllers
