These two ICs together form an Encoder and Decoder pair. Valid transmission; active high. Photograph just for reference. Return and Refund Policy. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. Virgin Galactic — Commercial Space Flight.

Decodr 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. We will notify you the result by email.

The input data code is decoded when no error ht1d2 unmatched codes are found. Supply voltage; 5V 2. Interface GPS with Arduino. 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. These are the 8-bit address bits, which is used to protect your data. Interface SD Card with Arduino. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins.


Full Name Email Address.

A valid transmission in indicated by a high signal at VT pin. If you want security you can connect any of the 8 pins to 5V to make it high. 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. 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. The serial input data is compared with the local addresses three times continuously.

It is very bt12d that your Decoder should have the same address of that of the encoder. We should set the bits in same pattern on Encoder and Decoder IC to pair them.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

TL — Programmable Reference Voltage. They are capable of Encoding 12 bit of information which consists of N address bits and N data bits. Actual product may vary from hr12d product photograph displayed above.

HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders. Please submit the url of the better price you saw. The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded.

The 4-bit data that is received can be obtained on pins AD0 dfcoder AD1 and an address of 8-bit has to be set using the pins A0 to A7. We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product.


This ICs are paired with each other.


It is mainly provided to interface RF and infrared circuits. In simple terms, Dfcoder converts the serial input into parallel outputs. Connected to the Ground of circuit.

Buy 15 or more pieces to get Free Shipping Option Availability: Arduino based GPS receiver. They can h12d be connected to LED to physically view the received data.

HT12D decoder – elektrojo Store

Skip to main content. Found this item with same quality and at a lower price but prefer to buy from robokits. Easy Interface with and RF or an Infrared transmission medium. In the above circuit I have set the 8-bit address data as 0b, by connecting hf12d address pins to ground. 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 hy12d the data.

They are paired with 2 12 series of encoders. If any valid data is received they can be obtained from these four pins.
