Valid transmission; active high. The data on 4 bit latch type output pins remain unchanged until new is received.

HT12D Decoder IC | HT12D Datasheet | Pin Diagram

This high-density System-in-Package SiP integrates controller, power switches, and support components. It is not mandatory to use it. The input data code is decoded when no error or unmatched codes are found. Dayasheet pin will go high when a data is received. A basic circuit diagram datasyeet 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.

TL — Programmable Reference Voltage.

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. If any valid data is received they can be obtained from these four pins. HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders.


It is mainly provided to interface RF and infrared circuits.

It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins. This IC has a total of yt12d pinsnine on either sides: Basically found in applications of remote control systems.

HT12E IC has four bit parallel data inputwhich it then converts to serial data output.

An LED can also be connected across this terminal to indicate output. These two ICs together form an Encoder and Decoder pair. Arduino based GPS receiver. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle bt12d data transfer.

SPI Module of Arduino. In simple terms, HT12D converts the serial input into parallel outputs. Skip to main content. 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. Interface SD Card with Arduino.

This pin powers the IC should use only 5V. Interface GPS with Arduino. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. Generally a resistor of value 51 KOhms can be used. What is Web Browser. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.

These pins are generally shorted by a resistor. This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc.

HT12D Decoder IC

This IC hasmany applications in short range remote controlling. The serial input data is compared with the local addresses three times continuously. This site uses cookies. This is an CMOS logic integrated circuit encoder.


To find out more, including how to control cookies, see here: In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. To know how a 4-bit data can be encoded and then send to the input pin of this IC, we have xatasheet understand the working of the HT12E Encoder IC which is given here.

Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. I am now going to tell you about to control a certain robot wirelessly rather than using wires.

The 4-bit data that hht12d 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. Supply voltage; 5V 2.

HT12D Datasheet

HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits. Gone are the days when we used to use wires to connect two devices to establish a communication path. Submitted by admin on 27 October This oscillator can be used by connecting these two pins through a 1M Resistor.

They are paired with 2 12 series of encoders. Choosing Motor For Robots.
