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: ✦

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

Generally a resistor of value 51 KOhms can be used. This site uses cookies. Choosing Battery for Robots.

HT12E Encoder IC | HT12E Datasheet | Pin Diagram & Description

Basically found in applications of remote control systems. 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.

A basic connection diagram for the HT12E IC is shown below Datasyeet the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Virgin Galactic — Commercial Space Flight.

Used for interfacing RF circuits generally MegaHz. If you want security you can connect any of the 8 pins to 5V to make it high. These pins are generally shorted by a resistor. I am now going to tell you about to control a certain robot wirelessly rather than using wires. Submitted by admin on 30 October This cycle is repeated as long as TE is kept low. These are the 8-bit address bits, which is used to protect your data.


For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data.

Transmission enable; active low. HT12E is an encoder integrated circuit of 2 12 series of encoders. These 12 bits are dqtasheet into 8 address bits and 4 data bits.

An LED can also be connected across this terminal to indicate output. The primary function of HT12E is to encode a bit and send it datsaheet through the output pin. Arduino based GPS receiver.

Thus this helps in setting up oscillations in the IC. Pull the Transmission Enable pin pin 14 to ground to activate transmission. As soon as TE returns to high, the encoder output completes its final cycle and then stops.

This data should be sent to the HT12D for decoding, it can either be sent directly through a wire or by using a ht12s medium like RF or IR. SPI Module of Arduino.

HT12E Encoder IC

This IC hasmany applications in short range remote controlling. The IC is has a wide range of operating voltage from 2. Skip to main content. TL — Programmable Reference Voltage. By continuing to use this website, you agree to their use. This is an CMOS logic integrated circuit encoder. Choosing Motor For Robots. 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.


Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. It is mainly used in interfacing RF and infrared circuits. They are paired with 2 12 series of decoders for use in remote control system applications. You can know to set up the HT12D after this from here. Interface SD Card with Arduino. It is very important that your Decoder should also have this same address for them to talk to each other.

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

HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. The Encoded 12 bit output data can be obtained from this pin.
