The Encoded 12 bit output data obtained from HT12E has to be given here.

HT12D Decoder IC | HT12D Datasheet | Pin Diagram

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. If any valid data is received they can ddatasheet obtained from these four pins. The input data code is decoded when no error or unmatched codes are found. Skip to main content.

It is very important that your Decoder should have the same address of that of the encoder. Gt12d can also be connected to LED to physically view the received data. We should set the bits in same pattern on Encoder datadheet Decoder IC to pair them. 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.


Arduino based GPS receiver. It is not mandatory to use it. They are paired with 2 12 series of encoders. Actual product may vary from the product photograph displayed above.

The 4-bit data decodre 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.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

Be the catasheet to write a review. Interface SD Card 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. Easy to Use, Versatile Robotics Kits 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 eatasheet to ground.

Virgin Galactic — Commercial Space Flight. Customers who bought this product also purchased Buy 15 or dataheet pieces to get Free Shipping Option Availability: So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.

Interface GPS with Arduino.

Choosing Battery for Robots. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. If you want security you can connect any of the 8 deecoder to 5V to make it high. The serial input data is compared with the local addresses three times continuously.


HT12D Decoder IC

The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded. 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.

A valid transmission in indicated by a high signal at VT pin. These two ICs together form an Encoder and Decoder pair. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. Return and Refund Policy. Submitted by admin on 27 October This oscillator can be used by connecting these two pins through a 1M Resistor. 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.

Easy Interface with and RF or an Infrared transmission medium. Photograph just for reference. HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits.
