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.

The Encoded 12 bit output data can be obtained from this pin. Notify of all new follow-up comments Notify of new replies to all my comments. Where are the input pins on the ic I would like to connect a potentiometer to the input on the ic for rc car. Gunasekaran, Am not sure about what you are asking. Why do we put a resistor between two pins of oscillator viz. It is mainly used in interfacing RF and infrared circuits.
The IC has a built in oscillator. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. These 12 bits are divided into 8 address bits and 4 data bits. But pins AD8-AD11 are not address icc, so we have only 8 pins for address A0-A7, which can provide only different addresses, so this IC is not good for production?
Supply voltage; 5V 2. So if you are working on a project which has h1t2e 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.
Quote and Order boards in minutes on: It is very important that your Decoder should also have this same address for them to talk to each other.
Calculating addresses, we are limited to 56 addresses per pair. Using the address pins we can provide 8 bit security code for ht21e data transmission between the encoder and the decoder.
HT12E Encoder IC
After receiving a low signal the HT12E starts the transmission of 4 data bits as shown in the timing diagram above. In ht12d decoder section, i am changing the address by giving delay. These two ICs together form an Encoder and Decoder pair. Hope it is clear now. TL — Programmable Reference Voltage. Unk, Your address should be unique and only know to your receiver end to avoid other source signal interference. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.
If the TE pin retains the low signal the cycle repeats as long as the low signal in the TE pin exists. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. Choosing Battery for Robots. Dear Frank Donald, Thank you for the reply and clarification. Rod, No we are limited to address per pair. Skip to main content. HT12E is capable of operating in a wide Voltage range from 2.
What is Web Browser. Choosing Motor For Robots. They can also be connected to switches to manually send and receive data.
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. Interface SD Card with Arduino.
HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet
This high-density System-in-Package SiP integrates controller, power switches, and support components. HT12E starts working with a low signal on the TE pin. This cycle is repeated as long as TE is kept low. Frank Donald is an Electronics and Communication Engineer icc loves building stuff in his free time.
These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits.
