Submitted by admin on 27 October Valid transmission; active high. What is Web Browser. 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. It is very important that your Decoder should have the same address of that of the decodrr. Interface GPS with Arduino. Customers who bought this product also purchased 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.

Buy 15 or more pieces to get Free Shipping Option Availability: 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. Return and Refund Policy. Mercury ball tilt switch 5mm dia. Found this item with same quality and at a lower price but prefer to buy from robokits.


The serial input data is compared with the local decover three times continuously. If any valid data is received they can be obtained from these four pins.

We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product. The input data code is decoded when no error or unmatched codes are found.

They are paired with 2 12 series of encoders. Skip to main content. Thanks a lot for helping us to maintain competitive prices. This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc.

HT12D/HT12F – Product Details – Holtek

It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins. This oscillator can be used by connecting these two pins through a 1M Resistor.

Actual product may vary from the product photograph displayed above. Interface SD Card with Arduino. Easy to Use, Versatile Robotics Kits Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.

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.


So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.

HT12D Decoder IC

Virgin Galactic — Commercial Space Flight. They can also be connected to LED to physically view the received data. TL — Programmable Reference Voltage.

This pin powers the IC should use only 5V. Full Name Email Address. Choosing Battery for Robots. 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 hf12d.

Choosing Motor For Robots. Easy Interface with and RF or an Infrared transmission medium. HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits. This high-density System-in-Package SiP integrates controller, power switches, and support components. The IC has a built in oscillator. 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.

In simple terms, HT12D converts the serial input into parallel outputs. It is mainly provided to interface RF and infrared circuits. These two ICs together form an Encoder and Decoder pair.
