How to use a HT12D RF Decoder. The primary function of HT12D is to decode the 12-bit that is received by the input pin. Since the IC comes with an in-built Oscillator it is very easy to make this IC work. The IC is should be powered by 5V (pin 18) and the ground pin (pin 9) is grounded.

2013年6月16日 · HT12D is a 2 12 series decoder IC (Integrated Circuit) for remote control applications manufactured by Holtek. It is commonly used for radio frequency (RF) wireless applications. By using the paired HT12E encoder and HT12D decoder we can transmit 12 bits of parallel data serially.

Of the 212 series of decoders, the HT12F has no data output pin but its VT pin can be used as a momentary data output. The HT12D, on the other hand, provides 4 latch type data pins whose data remain unchanged until new data are received. Decoder timing .
