HT12E Encoder IC can be used only with its pair HT12D. These two ICs together form an Encoder and Decoder pair. The capa- bility to select a TE trigger on the HT12E or a. DATA trigger on the HT12A/B/C further en- hances the application flexibility of the 2. The content and copyrights of the attached material are the property of its owner. Distributed by: ✦

Interface GPS with Arduino. 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. These two ICs together form an Encoder and Decoder pair.

HT12A/HT12E – Product Details – Holtek

Submitted by admin on 30 October Gone are the days when we used to use wires to connect two devices to establish a communication path.

This pin outputs the parallel data serially.

Simply put, HT12E converts the parallel inputs into serial output. HT12E has a transmission enable pin which is active low. Arduino based GPS receiver. Basically found in applications of remote control systems. You can know to set up the HT12D after this from here.

So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. This oscillator can be used by connecting these two pins through a 1M Resistor. These pins are generally shorted by a resistor. HT12E IC has four bit parallel data inputwhich it then converts to serial data output. HT12E is an encoder integrated circuit of 2 12 series of encoders. The primary function of HT12E is to encode a bit and send it out through the output pin.


The encoded bit can be obtained from the Dout pin pin Connected to the Ground of circuit.

These are the 8-bit address bits, which is used to protect your data. It is mainly used in interfacing RF and infrared circuits.

If you want security you can connect any of the 8 pins to 5V to make it high. Transmission enable; active low.

Thus this helps in setting up oscillations in the IC. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.

HT12E Encoder IC

After one complete cycle of data transfer the pin Datasheeet goes in high impedance state, thus indicating 1 cycle of data transfer. I am now going to tell you about to control a certain robot wirelessly rather than using wires. By continuing to use this website, you agree to their use.

Virgin Galactic — Commercial Space Flight.

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. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Choosing Motor For Robots.

The IC has a built in oscillator. They can also be connected to switches to manually send and receive data.


TL — Programmable Reference Voltage. Interface SD Card with Arduino. What is Web Browser. Generally a resistor of value 51 KOhms can be used.

HT12E Encoder IC | HT12E Datasheet | Pin Diagram & Description

They are paired with 2 12 series of decoders for use in remote control system applications. The Encoded 12 bit output jt12e can be obtained from this pin.

This IC has a total of 18 pinsnine on either sides: It is very important that your Decoder should also have this same address for them to talk to each other. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.

We should set the bits in same pattern on Encoder hy12e Decoder IC to pair them. An LED can also be connected across this terminal to indicate output.

HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. As soon as TE returns to high, the encoder output completes its final cycle and then stops. Can range from 2. SPI Module of Arduino. These 12 bits are divided into 8 address bits and 4 data bits.

This cycle is repeated as long as TE is kept low. This site uses cookies.
