HT12D Decoder IC

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.

Interface SD Card with Arduino. TL — Programmable Reference Voltage. Easy to Use, Versatile Robotics Kits Buy 15 or more pieces to get Free Shipping Option Availability: We will notify you the result by email.

The input data code is decoded when no error or unmatched codes are found. SPI Module of Arduino. Valid transmission; active high. It is mainly provided to interface RF and jc circuits.


HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

Customers who bought this product also deecoder Submitted by admin on 27 October 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. The data on 4 bit latch type output pins remain unchanged until new is received. Choosing Battery for Robots.

The serial input data is compared with the local addresses three times continuously. TB Stepper Motor Driver 4. Interface GPS with Arduino. If any valid data is received they can be obtained from these four pins.

For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. This ICs are paired with each other.

Return and Refund Policy. They are paired with 2 12 series of encoders. icc

This high-density System-in-Package SiP integrates controller, power switches, and support components. HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders.

HT12D/HT12F – Product Details – Holtek

The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded. A valid transmission in indicated by a high signal at VT pin. This pin will go high when a data is received. Found this item with defoder quality and at a lower price but prefer to buy from robokits.


This oscillator can be used by connecting these two pins through a 1M Resistor.

Photograph just for reference. In simple terms, HT12D converts the serial input into parallel outputs. This pin powers the IC should use only 5V.

We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product. It is very important that your Decoder should have the same address of that of the encoder. If you want security you can connect any of the 8 pins to 5V to make it high. Supply voltage; 5V 2. 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. 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.
