Ht12e Circuit Diagram. The ht12d and ht12e are 4 data bit encoder and decoder modules. As said they have 4 data bit and 8 addresss bit these 8 address bits has to be set same on both the encoder and.
This ht12e ic capable of converting 12 bit parallel data inputs into serial outputs. Ht12e encode working the primary function of the encoder is to encode the 12 bit parallel input data and then forward it towards the output pin. Ht12e block diagram ht12e is able to operate in a wide voltage range from 2 4v to 12v and has a built in oscillator which requires only a small external resistor.
This pin goes to vcc or the positive of our power source.
This means that we can make 2 4 16 16 different combinations of inputs and outputs. Don t change the value of this resistor if you make that your circuit it doesn t work. The ics power source is activated by pins ad8 ad11 ht12a ht12e rev. Its power consumption is very low standby current is 0 1μa at 5v vdd and has high immunity against noise.
