Ht12d Circuit. For decoding a data the ic will requires an oscillator luckily this ic has one in built. They are paired with 212 series of encoders.
Since the ic comes with an in built oscillator it is very easy to make this ic work. They are paired with 212 series of encoders. The primary function of ht12d is to decode the 12 bit that is received by the input pin.
It is mainly provided to interface rf and infrared circuits.
With a little bit more work and complexity it may be multiplied many times using some binary counter ic and ne555 as clock source. By using the paired ht12e encoder and ht12d decoder we can transmit 12 bits of parallel data serially. It is mainly provided to interface rf and infrared circuits. Actually you have 16 channels per single ht12d e chip to be more precisely it s 4bits of data.
