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.

SPI Module of Arduino. Actual product may vary from the product photograph displayed above. Supply voltage; 5V 2. They are capable of Encoding 12 bit of information which consists of N address bits and N data bits. Choosing Motor For Robots. These are the 8-bit address bits, which is used to protect your data.

These two ICs together form an Encoder and Decoder pair. We should set the bits in same pattern on Encoder and Decoder IC to pair them.

Please submit the url of the better price you saw. 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. Arduino based GPS receiver. HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders.



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. TB Stepper Motor Driver 4. We will lauch an immediate investigation and try our best to beat the encodet, if it proves to be the same product. Choosing Battery for Robots. Customers who bought this product also purchased Virgin Galactic — Commercial Space Flight.

We will notify you the result by email. Submitted by admin on 27 October This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc.

Interface GPS with Arduino. Full Name Email Address.

In simple terms, HT12D converts the serial input into parallel outputs. Mercury ball tilt switch 5mm dia. 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.

HT12D Decoder IC

In the above circuit I have set encorer 8-bit address data as 0b, by connecting all address pins to ground. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built.

Buy 15 or more 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.


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.

Skip to main content. Return and Refund Policy. They can also be connected to LED to physically view the received data. 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.

Found this item with same quality and at a lower price but prefer to buy from robokits. If any valid data is received they can be obtained emcoder these four pins. 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.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

TL — Programmable Reference Voltage. It is not mandatory to use it. Easy to Use, Versatile Robotics Kits It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins.
