This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc. A valid transmission in indicated by a high signal at VT pin.

HT12D Datasheet

The Encoded 12 bit output data obtained from HT12E has to be given here. The serial input data is compared with the local addresses three times continuously. If you daasheet security you can connect any of the 8 pins to 5V to make it high.

HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders. Submitted by admin on 27 October 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. The 4-bit data that is received can be ht122d on pins AD0 to AD1 and an address of 8-bit has to be set using the pins A0 to A7.


Interface GPS with Arduino. HT12D ht12x capable of decoding 12 bits, of which 8 are address bits and 4 are data bits.

HT12D Decoder IC

The IC has a built in oscillator. Choosing Battery for Robots. What is Web Browser. In simple terms, HT12D converts the serial input into parallel outputs. Choosing Motor For Robots. We should set the bits in same pattern on Encoder and Decoder IC to pair them. This pin powers the IC should use only 5V. The data on 4 bit latch type output pins remain unchanged until new is dwtasheet.

To know how a 4-bit data can be encoded and datasyeet send to the input pin of this IC, we have to understand the working of the HT12E Encoder IC which is given here. In the above circuit I have set the dataasheet address data as 0b, by connecting all address pins to ground.

The input data code is decoded when no error or unmatched codes are found. 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.

It is not mandatory to use it. Interface SD Card with Arduino.

So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. Virgin Galactic — Commercial Space Flight.


Arduino based GPS receiver. It is very important that your Decoder should have the same address of that of the encoder. It is mainly provided to interface RF and infrared circuits. These two ICs together form an Encoder dataheet Decoder pair. They can also be connected to LED to physically view the received data.

If any valid data is received they can be obtained from these four pins. Dztasheet oscillator can be used by connecting these two pins through a 1M Resistor.

Connected to the Ground of circuit. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Hg12d or Fire alarm system etc. These are the 8-bit address bits, which is used to protect your data. SPI Module of Arduino. Supply voltage; 5V 2.

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

This high-density System-in-Package SiP integrates controller, power switches, and support components.
