So if you are working on a project which has to transmit a 4-bit data from one end ht12x other either by wire or wireless then this IC pair will be best suited for you. A basic circuit diagram for the HT12D IC is shown below In ht12c above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.

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 ht12v the pins A0 datashet A7. 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. This pin powers the IC should use only 5V. If you want security you can connect any of the 8 pins to 5V to make it high.


Thus this helps in setting up oscillations in the IC. They are paired with 2 12 series of encoders. Generally a resistor of htt12d 51 KOhms can be used.

It is not mandatory to use it. This high-density System-in-Package SiP integrates controller, power switches, and support components. What is Web Browser. Arduino based GPS receiver. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built.

Basically found in applications of remote control systems. We should set the bits in same pattern on Encoder and Decoder IC to pair them. They can also be connected to LED to physically view the received data.

This pin outputs the parallel data serially. In simple terms, HT12D converts the serial input into parallel outputs.

These are the 8-bit address bits, datashewt is used to protect your data. A valid transmission in indicated by a high signal at VT pin. The serial input data is compared with the local addresses three times continuously.

It is mainly provided to interface RF and infrared circuits. Gone are the days when we used to use datasheeet to connect two devices to establish a communication path. This oscillator can be used by connecting these two pins through a 1M Resistor.


HT12D/HT12F – Product Details – Holtek

The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded. Skip to main content. Connected to the Ground of circuit. SPI Module of Arduino. The Encoded 12 bit output data obtained from HT12E has to be given here.

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

HT12D Decoder IC

The input data code is decoded when no error or unmatched codes are found. This IC hasmany applications in short range remote controlling.

Now first of all let me acquaint you about these two integrated circuits: This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc. TL — Programmable Reference Voltage.
