IC HT12E PDF
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.

As soon as TE returns to high, the encoder output completes its final cycle and then stops. No mechanical switching involved. These 12 bits are divided into 8 address bits and 4 data bits.
The IC is has a wide range of operating voltage from 2. HT12E has a transmission enable pin which is active low. Transmission enable; active low.
These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. Using the address pins we can provide 8 bit security code for secured data transmission between the encoder and the decoder. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.
Thank you and I will let ht1e know the working of the circuit. Hii Frank, I am interfacing 4 encoder with different address configuration. Dear Frank Thank you for your reply. Choosing Motor For Robots.
Choosing Battery for Robots. 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. Unk, Your i should be unique and only know to your receiver end to avoid other source signal interference.
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. The Encoded 12 bit output data can be obtained from this pin.
If you want security you can connect any of the 8 pins to 5V to make it high. A basic connection diagram for the HT12E IC is shown below In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Connected to the Ground of circuit. They are paired with 2 12 series of decoders for use in remote control system applications.
It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. It is mainly used in interfacing RF and infrared circuits. These two ICs together form an Encoder and Yt12e pair. HT12E is capable of operating in a wide Voltage range from 2. The encoder IC will be in standby mode if the TE ht12d is disabled and thus the status of this pin was necessary for encoding process. Kindly repost your question.
HT12E Encoder IC
Interface GPS with Arduino. Simply put, HT12E converts the parallel inputs into serial output.
HT12E starts working with a low signal on the TE pin. They can also be connected to switches to manually send and receive data. There is no use of that IC here. Why do we put a resistor between two pins of oscillator viz.
Working of HT12E Encoder IC – Gadgetronicx
The primary function of HT12E is to encode a bit and send it out through the output pin. This pin iv to be connected to Ground 0V to enable the Transmission. The following two tabs change content below. What is Web Browser. The IC has a built in oscillator. 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 buy online in India – Robomart
I have a doubt. Thank you for your reply. 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?
But if i want to transmit data in 5th encoder, in which pin of encoder sholud i provide data to encoder??? SPI Module of Arduino. Calculating addresses, we are limited to 56 addresses per pair.
