HT12D Decoder IC

Used for interfacing RF circuits generally MegaHz. SPI Module of Arduino.

Submitted by admin on 27 October If any valid data is received they can be obtained from these four pins. Now first of all let me acquaint you about these two integrated circuits: This IC datashert applications in short range remote controlling.

At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data. Supply voltage; 5V 2.

The input data code is decoded when no error or unmatched codes are found. 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.


This IC has a total of 18 pinsnine on either sides: Connected to the Ground of circuit.

The 4-bit data that is received can be obtained on pins AD0 to AD1 and an address of 8-bit has to be set using the pins A0 to A7. Basically found in applications of remote control systems.

This oscillator can be used by connecting these two pins through a 1M Resistor. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. This pin powers the IC should use only 5V. To find out more, including how to control cookies, see here: An LED can also be connected across this terminal to indicate output.

It is mainly provided to interface RF and infrared circuits. Skip to main content. This dahasheet can be used by connecting these two pins through a 1M Resistor 17 Valid Transmission VT This pin will go high when a data is received.

If you want security you can connect any of the 8 pins to 5V to make it high. This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc. Thus this helps in setting up oscillations in the IC. This pin outputs the parallel data serially. HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits. They are paired with 2 12 series of encoders.


In simple terms, HT12D converts the serial input into parallel outputs. What is Web Browser.

The Encoded 12 bit output data obtained from HT12E has to be given here. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer. Valid transmission; active high.

Interface GPS with Arduino. Gone are the days when we used to use wires to connect two devices to establish a communication path. This high-density System-in-Package SiP integrates controller, power switches, and support components. In additional to itit ht12x has 8 address lines which can generally be grounded along with the pin number 9.
