Supply voltage; 5V 2. A basic connection diagram for the HT12E 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. Skip to main content.

Choosing Motor For Robots. These are the 8-bit address bits, which is used to protect your data. Arduino based GPS receiver. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

Choosing Motor For Robots. Transmission enable; active low. These pins are generally shorted by a resistor. For decoding darasheet data the IC will requires an oscillator, luckily this IC has one in-built. Interface GPS with Arduino. The IC has a built in oscillator.

HT12D/HT12F – Product Details – Holtek

In simple terms, HT12D converts the serial input into parallel outputs. These two ICs together form an Encoder and Decoder pair.


It is mainly used in interfacing RF and infrared circuits. At low signal data is transferred via antenna and received by Receiver IC which then decodes it to ht1e parallel data.

In this image I have made all four data bits as zero lowwhen this is decoded we will get the same kind of bits on the output side of HT12D, similarly we can make any changes on these 4-bits and they will be reflected on the output side of the HT12D decoder IC. Basically found in applications of remote control systems.

HT12E Encoder IC

Valid transmission; active high. This IC has a total of 18 pinsnine on either sides: The IC is has a wide range of operating voltage from 2. An LED can also datashert connected across this terminal to indicate output. So ht12f of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.

Now first of all let me acquaint you about these two integrated circuits: These 12 bits are divided into 8 address bits and 4 data bits. TL — Programmable Reference Voltage.

It is very important that your Decoder should also have this same address for them to talk to each other. Skip to content Gone are the days when we used to use wires to connect two devices to establish a communication path. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Choosing Battery for Robots. They are paired with 2 12 series of decoders for use in remote control system applications.


This high-density System-in-Package SiP integrates controller, power switches, and support components. Generally a resistor of value 51 KOhms can be used. Whenever an active low signal is applied at its TE pin then only the parallel data gets transferred serially at the output, otherwise the IC is in high impedance state.

This cycle is repeated as long as TE is kept low. SPI Module of Arduino. 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 Decoder IC

Connected to the Ground of circuit. HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders. Gone are the days when we used to use wires to connect two devices to establish a communication path.

Pull the Transmission Enable pin pin 14 to ground to activate transmission. The Encoded 12 bit output data can be obtained from this pin.
