HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

Gone are the days when we used to use wires to connect two devices to establish a communication path. This is an CMOS logic integrated circuit encoder. Basically found in applications of remote control systems. Used for interfacing RF circuits generally MegaHz.


This IC hasmany applications in short range remote controlling. HT12E IC has four bit parallel data inputwhich it then converts to serial data output.

In additional to itit also has 8 address hh12d which can generally be grounded along with the pin number 9. Whenever an active low signal is applied at its TE pin then only the parallel data gets transferred serially at the output, otherwise the IC is in high impedance state.

At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data. These pins are generally shorted by ht12r resistor. Generally a resistor of value 51 KOhms can be used.

Thus this helps in setting up oscillations in the IC.

This pin outputs the parallel data serially. An LED can also be connected across this terminal to indicate output. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer.

I am now going to tell you about to control a certain daasheet wirelessly rather than using wires.


Now first of all let me acquaint you about these two integrated circuits: This IC has a total of 18 pinsnine on either sides: This site uses cookies.
