By using the paired HT12E encoder and HT12D decoder we can transmit 12 bits of parallel data serially. HT12D simply converts serial data to its input (may be. IC HT12D can be used only with its pair HT12E. These two ICs together form an Encoder and Decoder pair. They are bit. The HT12E Encoder ICs are series of CMOS LSIs for Remote Control system applications. They are capable of Encoding 12 bit of information which consists of 8.

It is mainly provided to interface RF and infrared circuits. Found this item with same quality and at a lower price but prefer to buy from robokits. It is very important that your Decoder should have the same address of that of the encoder.

These two ICs together form an Encoder and Decoder pair. ht2d


Arduino based GPS receiver. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins. Actual product may vary from the product photograph displayed above.

They are capable of Encoding 12 bit of information which consists of N address bits and N data bits. Valid transmission; active high.

Choosing Motor For Robots. Buy 15 or more pieces to get Free Shipping Option Availability: Interface SD Card with Arduino.


Customers who bought this product also purchased Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.

We should set the bits in same pattern on Encoder and Decoder IC to pair them. The data on 4 bit latch type output pins remain unchanged until new is received.

The Encoded 12 bit output data obtained from HT12E has to be given here. TB Ht1d2 Motor Driver 4. Supply voltage; 5V 2. Be the first to write a review.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

Submitted by admin on 27 October Virgin Galactic — Commercial Space Flight. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. Mercury ball tilt switch 5mm dia. Please submit the url of the better price you saw. The IC is encode be powered by 5V pin 18 and the ground pin pin 9 is grounded. They are paired with 2 12 series of encoders. This pin will go high when a data is received.

Choosing Battery for Robots.

The Decoder receive the serial address and data from its corresponding decoder, transmitted by a carrier using an RF transmission medium and gives output to the output pins after processing the data. We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product.


A valid transmission in indicated by a high signal at VT pin. 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 you want security you can connect any of the 8 pins to 5V to make it high. If any valid data is received they can be obtained from these four pins. In simple terms, HT12D converts the serial input into parallel outputs. Photograph just for reference.

The serial input data is compared with the local addresses three times continuously. 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. HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders. 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.

This pin powers the IC should use only 5V. Thanks a lot for helping us to maintain competitive prices. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built.
