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. Valid transmission; active high. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.

They are capable of Encoding 12 bit of information which consists of N address bits and N data bits. 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. In simple terms, HT12D converts the serial input into parallel outputs. This high-density System-in-Package SiP integrates controller, power switches, and support components.

Thanks a lot for helping us to maintain competitive prices. Interface SD Card with Arduino.

Customers who datasheef this product also purchased Skip to main content. Interface GPS with Arduino. This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc.


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

Submitted by admin on 27 October Datadheet 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.

The data on 4 bit latch type output pins remain unchanged until new is received. Found this item with same quality and at a lower price but prefer to buy from robokits. HT12D is a deccoder integrated circuit that belongs to 2 12 series of decoders.

If you want security you can connect any of the 8 pins to 5V to make it high. It is very important that your Decoder should have the same address of that of the ht12x. We will notify you the result by email. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Connected to the Ground of circuit. The IC has a built in oscillator. TL — Programmable Reference Voltage.

Mercury ball tilt switch 5mm dia. Be the first to write a review. Arduino based GPS receiver. It is mainly provided to interface RF and infrared circuits. Datasehet Galactic — Commercial Space Flight.

SPI Module of Arduino. They can also be connected to LED to physically view the received data.


HT12D/HT12F – Product Details – Holtek

This pin powers the IC should use only 5V. Return and Refund Policy.

TB Stepper Motor Driver 4. This oscillator can be used by connecting hr12d two pins through a 1M Resistor. HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits.

This ICs are paired with each other. Easy Interface with and RF or an Infrared transmission medium. Buy 15 or more pieces to get Free Shipping Option Availability: If any valid data is received they can be obtained from these four pins.

This pin will go high when a data is received. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins. 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 datasheeg suited for you. Choosing Motor For Robots. Choosing Battery for Robots.

HT12D Decoder IC

They are paired with 2 12 series of encoders. These two ICs together form an Encoder and Decoder decover. What is Web Browser. We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product.
