HT12E is a series encoder IC (Integrated Circuit) for remote control applications. It is commonly used for radio frequency (RF) applications. By using the. HT12E Encoder IC can be used only with its pair HT12D. These two ICs together form an Encoder and Decoder pair. The HT12E Encoder IC starts working by giving enable signal to the Transmission Enable pin. The 4-word data will be encoded until the TE pin.

Hg12e are address combinations which I feel will do a good job in securing the communication and keep away interference. Kindly repost your question. You can know to set up the HT12D after this from here.
HT12E starts working with a low signal on the TE pin. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. Rod, No we are limited to address per pair. HT12E ix capable of operating in a wide Voltage range from 2. But now, if i want to connect more than 4 encoder how do i configure data pins?
So out of the bits 8-bits will be used to lc address and the remaining 4-bit will be used to transmit data. HT12E iic an encoder integrated circuit of 2 12 series of encoders. Request you idea on this. H12e are paired with 2 12 series of decoders for use in remote control system applications. Using the address pins we can provide 8 bit security code for secured data transmission between the encoder and the decoder.
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. Video ht112e, blogging and programming are the things he loves most.
The 4-bit data that has to be sent has to be given to the pins AD0 to AD1 and an address of 8-bit has to be set using the pins A0 to A7. If you need more address I suggest you to look for any other encoders and decoders with more address combinations.
HT12E Encoder IC
But pins AD8-AD11 are not address pins, so we have only 8 pins for address A0-A7, which can provide only different addresses, so this IC is not good for production? This cycle is repeated as long as TE is kept low. Can range from 2. And the output cycle will repeats based on the status of the TE pin in the IC. The encoder IC will be in standby mode if the TE pin is disabled and thus the status of this pin was necessary for encoding process.
HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet
The IC is has a wide range of operating voltage from 2. The encoded bit can be obtained from the Dout pin pin Arduino based GPS receiver.
We should set the bits in same pattern on Encoder and Decoder IC to pair them. In this image I have made jc 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.
Transmission enable; active low.
Simply put, HT12E converts the parallel inputs into serial output. Regarding the addressing you can use a simple switch to feed your desired address. Interface SD Card with Arduino. Why do we put a resistor between two pins of oscillator viz.
Interface GPS with Arduino. Dear Frank Donald, Thank you for the reply and clarification. It is mainly used in interfacing RF and infrared circuits.
Hii Frank, I am interfacing 4 encoder with different address configuration. The encoder and decoder should use the same address and data format.
