The HT12E is a 2^12 encoder in 18 pin DIP package. This is CMOS LSI for remote control system applications. It is capable of encoding information which. Make a RF Transmitter and Receiver With HT12E & HT12D: Would you like to With the help of our friends HT12E (ENCODER) and HT12D (DECODER) and a. Dec 8, HT12E is an encoder integrated circuit of 2 12 series of encoders. They are paired with 2 12 series of decoders for use in remote control system.

HT12E Encoder IC | HT12E Datasheet | Pin Diagram & Description

Can ht1e used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. But if i want to transmit data in 5th encoder, in which pin of encoder sholud i provide data to encoder???

This cycle is repeated as long as TE is kept low. The encoder and decoder should use the same address and encoderr format. We should set the bits in same pattern on Encoder and Decoder IC to pair them. HT12E has a transmission enable pin which is active low.

Connected to the Ground of circuit. SPI Module of Arduino. HT12E is an encoder integrated circuit of 2 12 series of encoders. There is no use of that IC here. Thank you for the reply and clarification. However if you need to have more address combinations then you might want to look for other encoder-decoder pair available in the market. In ht12d decoder section, i am changing the address by giving delay. Gunasekaran, Am not sure about what you are asking.


This cycle is repeated as long as TE is kept low. Simply put, HT12E converts the parallel inputs into serial output. If you want security enccoder can connect any of the encoser pins to 5V to make it high. And the output cycle will repeats based on the status of the TE pin in the IC. After receiving a low signal the HT12E starts the transmission of 4 data bits as shown in the timing diagram above.

Dear Frank Thank you for your reply.

Hg12e is very important that your Decoder should also have this same address for them to talk to each other. These are the 8-bit address bits, which is used to protect your data. Arduino based GPS receiver. The IC has a built in oscillator. Notify of all new follow-up comments Notify of new replies to all my comments.

Transmission enable; active low. If the TE pin retains the low signal the cycle repeats as long as the low signal in the TE pin exists. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. Dear Frank Donald, Thank you for the reply and clarification. Where are the input pins on the ic I would like to connect a potentiometer to the input on the ic for rc car. The query I raised about is ebcoder addressing i. Request you idea on this. Virgin Galactic — Commercial Space Flight.

Pull the Transmission Enable pin pin 14 to ground to activate transmission.


Regarding the addressing you can use a simple ecnoder to feed your desired address. These two ICs together form an Encoder and Decoder pair. You can know to set up the HT12D after this from here.

The above diagram shows the practical set up of the HT12E encoder IC for better understanding on the working. 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. HT12E fncoder working with a low signal on the TE pin.

The following two tabs change content below. Video games, blogging and programming are the things he loves most. The encoder IC will enncoder in standby mode if the TE pin is disabled and thus the status of this pin was necessary for encoding process. Quote and Order boards in minutes on: HT12E begins a 4-word transmission cycle upon receipt of a transmission enable.

But pins AD8-AD11 are not address pins, so we have only 8 pins for address A0-A7, which can sncoder only different addresses, so this IC is not good for production? But now, if i want to connect more than 4 encoder how do i configure data pins?
