HT12D Decoder IC

It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins. Generally a resistor of value 51 KOhms can be used. Supply voltage; 5V datasheey. Valid transmission; active high. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer. At low signal data is transferred via antenna and received by Receiver IC which datasheer decodes it to original parallel data.

So if you are working on a project which has to transmit a 4-bit data from one end to other either by wire or wireless then this IC pair will be best suited for you. These are the 8-bit address bits, which is used to protect your data. HT12E IC has four bit parallel data inputwhich it then converts to serial data output.


Choosing Motor For Robots. Can be used in Home automation datssheet short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Used for interfacing RF circuits generally MegaHz. Virgin Galactic — Commercial Space Flight. It is not mandatory to use it. This IC has a total of 18 pinsnine on either sides: Now first of all jt12d me acquaint you about these two integrated circuits: The Encoded 12 bit output data obtained from HT12E has to be given here.

A valid transmission in indicated by a high signal at VT pin.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

They can also be connected to LED to physically view the received data. This is an CMOS logic integrated circuit encoder. The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded. Whenever an active low signal is applied at its TE pin then only the parallel data gets transferred serially at the output, otherwise datssheet IC is in high impedance state.

The input data code hht12d decoded when no error or unmatched codes are found. Submitted by admin on 27 October Arduino based GPS receiver.

These two ICs together form an Encoder and Decoder pair. The IC has a built in oscillator. This oscillator 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.

An LED can also be connected across this terminal to indicate output. This site uses cookies. The serial input data is compared with the local addresses three times continuously.


SPI Module of Arduino. What is Web Browser. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. In additional to itit also has 8 address lines which can generally datasheett grounded along with the pin number 9.

To know how a 4-bit data can be encoded and then send to the input pin of this IC, we have to understand the working of the HT12E Encoder IC which is given here. They are paired with 2 12 series of encoders. A basic circuit diagram for the HT12D IC is shown below In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.

This high-density System-in-Package SiP integrates controller, power switches, and support components. This pin powers the IC should use only 5V.

HT12D Datasheet

By continuing to use this website, you agree to their use. Basically found in applications of remote control systems. This pin outputs the parallel data serially. The data on 4 bit latch type output pins remain unchanged until new is received.

So out of the bits 8-bits will be used to set address and the remaining datashheet will be used to transmit data. It is very important that your Decoder should have the same address of that of the encoder.
