I am using HT12E, for a rf transmitter circuit. As per the datasheet HT12E is a 2¹² encoder.
Ideally such an encoder must have 2¹² inputs and 12 outputs. In addition to that all the inputs should be 1 exclusively.
When i look at the IC, I see 12 inputs A0-A7 + AD8-AD11, which go into the transmission gate circuit of the IC.
Can someone help me understand this part of the working ?
