TL — Programmable Reference Voltage. Connected to the Ground of circuit. They are capable of Encoding 12 bit of decoeer which consists of N address bits and N data bits.

TB Stepper Motor Driver 4. Easy Interface with and RF or an Infrared transmission medium. It is not mandatory to use it. Easy to Use, Versatile Robotics Kits 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. 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 decodeer.

Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins.


Virgin Galactic — Commercial Space Flight. Valid transmission; active high. If any valid data is received they can be obtained from these four pins. SPI Module of Arduino. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built.

Supply voltage; 5V 2. Choosing Battery for Robots. In the above circuit I have set ht1d2 8-bit address data as 0b, by connecting all address pins to ground. We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product.

HT12D/HT12F – Product Details – Holtek

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. The IC is should be powered by 5V pin 18 and the ground pin pin 9 is datazheet. We will notify you the result by email. The serial input data is compared with the local addresses three times continuously.

We should set the bits in same pattern on Encoder and Decoder IC to pair them. 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.

Be the first to write a review. Fatasheet to main content.

HT12D Decoder IC

If you want security you can connect any of the 8 pins to 5V to make it high. Photograph just for reference. They are paired with 2 12 series of encoders. The Encoded 12 bit output data obtained from HT12E has to be given here. This pin powers the IC should use only 5V. These are the 8-bit address bits, which datashee used to protect your data. Full Name Email Address.


Found this item with same quality and at a lower price but prefer to buy from robokits. This ICs are paired with each other.

It is very important that your Decoder should have the same address of that of the encoder.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders. A valid transmission in indicated by a high signal at VT pin. Interface SD Card with Arduino. Customers who bought this product decodrr purchased It is mainly provided to interface RF and infrared circuits. The input data code is decoded when no error or unmatched codes are found.

Buy 15 or more pieces to get Free Shipping Option Availability: Please submit the url of the better price you saw. This high-density System-in-Package SiP integrates controller, power switches, and support components.

The IC has a built in oscillator.

HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits.
