HT-12E. Encoder IC.
The HT12E encoder is a CMOS LSI for remote control system applications. It will interface to RF transmitter modules to create a secure single or multiple channel RF remote control transmitter. The oscillator is configured simply with the addition of a resistor. 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 transmission medium upon receipt of a trigger signal.
Features:
-Operating voltage: 2.4V~12V.
-Low power and high noise immunity CMOS technology.
-Low standby current: 0.1uA (typ.) at VDD=5V. -Minimum transmission word: Four words.
-Built-in oscillator, needs only 5% resistor.
-Data code has positive polarity.
-Minimal external components.
-Secure and robust protocol.
-Ideal for remote control and security applications.
-Compatible with the HT12D decoder IC.
