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.

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. Choosing Motor For Robots. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. It is very important that your Decoder should have the same address of that of the encoder. They are paired with 2 12 series of encoders. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins.

The data on 4 bit latch type output pins remain unchanged until new is received. Valid transmission; active high. The Encoded 12 bit output data obtained from HT12E has to be given here. In simple terms, HT12D converts the serial input into parallel outputs. Easy to Use, Versatile Robotics Kits This ICs are paired with each other.

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.

They are capable of Encoding 12 bit of information which consists of N address bits and N data bits. They can also be connected to LED to physically view the received data. Interface SD Card with Arduino.

This series of decoders are mainly used for remote control system applications, like encodee alarm, car door controller, security system etc. It is mainly provided to interface RF and infrared circuits. These two ICs together form an Encoder and Decoder pair. Photograph just for reference.

SPI Module of Arduino.

HT12D Decoder IC

This pin powers the IC should use only 5V. Be the first to write a review. Arduino based GPS receiver. Choosing Battery for Robots.

HT12D Decoder IC | HT12D Datasheet | Pin Diagram

Full Name Email Address. The input data code is decoded when no error or unmatched codes are found.

The serial input data is compared with the local addresses three times continuously. Return and Refund Policy. We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product. Supply voltage; 5V 2.


Easy Interface with and RF or an Infrared transmission medium. 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 will go high when a data is received. Customers who bought this product also purchased Interface GPS with Arduino. We will notify you the result by email. Skip to main content. This oscillator can be used by connecting these two pins through a 1M Resistor.

What is Web Browser. Thanks a lot for helping us to maintain competitive prices. TB Stepper Motor Driver 4.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

Virgin Galactic — Commercial Space Flight. Please submit the url of the better price you saw. 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.
