Operating voltage:2.4V~12V for the HT12E Low power and high noise immunity CMOS technology Minimum transmission word¶s of 4 words for the HT12E Built-in oscillator needs only 5% resistor Data code has positive polarity Minimal external components HT12E: 18-pin DIP/20-pin SOP package
The 2^12 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 12N 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 . Transmission is enabled by applying a low signal to the TE pin.
