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.

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 applications.
TL — Programmable Reference Voltage. This pin has to be connected to Ground 0V to enable the Transmission. Frank Donald December 24, 59 Comments. Video games, blogging and programming are the things he loves most.
Interface GPS with Arduino. It is mainly used in interfacing RF and infrared circuits. We should set the bits in same pattern on Encoder and Decoder IC to pair them. 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? So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.
HT12E starts working with a low signal on the TE pin. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits.
The encoder and decoder should use the same address and data format. 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 Encoder IC
The IC is has a wide range of operating voltage from 2. This oscillator ht12d be used by connecting these two pins through a 1M Resistor. I have 5v 12d cut and 12v 12e ckt. Thank you for the reply and clarification.
Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time. The above diagram shows the practical set up of the HT12E encoder IC for better understanding on the working.
Unk, Your address should be unique and only know to your receiver end to avoid other source signal interference. However if you need to have more address combinations then you might want to look for other encoder-decoder pair available jc the market.
Calculating addresses, we are limited to 56 addresses per pair. Supply voltage; 5V 2. Request you idea on this. In the above circuit I have icc the 8-bit address data as 0b, by connecting all address pins to ground. HT12E is capable of operating in a wide Voltage range from 2.
Ut12e to main content. SPI Module of Arduino. Arduino based GPS receiver. If you need more address I suggest you to look for any other encoders and decoders with more address combinations. Dear Frank Donald, Thank you for the reply and clarification. Can range from 2. Notify of all new follow-up comments Notify of new replies to all my comments.
There is no use of that IC here.
After receiving a low signal the HT12E starts the transmission of 4 data bits as shown in the timing diagram above. You can know to set up the HT12D after this from here. No mechanical switching involved. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.
Dear Frank Thank you for your reply. I have a doubt. ULN was a transistor array IC used for driving high power devices.
