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.

We will notify you the result by email. The input data code is decoded when no error or unmatched codes are found. Mercury ball tilt switch 5mm dia.

The data on 4 bit latch type output pins remain unchanged until new is received. Photograph just for reference.

Connected to the Ground of circuit. Found this item with same quality and at a lower price but prefer to buy from robokits.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

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 not mandatory to use it. 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.


What is Web Browser. Interface SD Card with Arduino.

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 gt12d the same product. Choosing Battery for Robots. If you want security you can connect any of the 8 pins to 5V to make it high. The IC has a built in oscillator. This ICs are paired with each other. The 4-bit data that is received can be obtained on pins AD0 to AD1 and an address of 8-bit has to be set using the pins A0 to A7.

These are the 8-bit address bits, which is used to protect eencoder data.

HT12D Decoder IC

It is very important that your Decoder should have the same address of that of the encoder. This pin powers the IC should use only 5V. eencoder

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

Full Name Email Address. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. encofer


Actual product may vary from the product photograph displayed above. TB Stepper Motor Driver 4. The serial input data is compared with the local addresses three times continuously. Submitted by admin on 27 October
