Ht12d Ic. We just have to connect the osc1 and osc2 pin 15 16 through a 470k resistor to invoke it. Since the ic comes with an in built oscillator it is very easy to make this ic work.
For decoding a data the ic will requires an oscillator luckily this ic has one in built. It is commonly used for radio frequency rf wireless applications. 2 12 series of decoders ht12d datasheet ht12d circuit ht12d data sheet.
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. We just have to connect the osc1 and osc2 pin 15 16 through a 470k resistor to invoke it. Ht12d simply converts serial data to its input may be received through rf receiver to 12 bit parallel data. Mostly remote control applications have this technology.
