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.

But if i want to transmit data in 5th encoder, in which pin of encoder sholud i provide data to encoder??? I have a doubt. Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time.

Quote and Order boards in minutes on: For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.

However if you need to have more address combinations then you might want to look for other encoder-decoder pair available in the market. Regarding the addressing you can use a simple switch to feed your desired address. Calculating iic, we are ht122e to 56 addresses per pair. The primary function of HT12E is to encode a bit and send it out through the output pin. There is no use of that IC here.


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

As soon as TE returns to high, the encoder output completes its final cycle and then stops. Dear Frank Thank you for your reply. If you want security you can connect any of the 8 pins to 5V to make it high. These two ICs together form an Encoder and Decoder pair.

The IC is has a wide range of operating voltage from 2. They are paired with ht12r 12 series of decoders for use in remote control system applications.

After receiving a low signal the HT12E starts the transmission of 4 data bits as shown in the timing diagram above. This high-density System-in-Package SiP integrates controller, power switches, and support components.

Submitted by admin on 30 October Rod, No we are limited to address per pair. In this image I have made all 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. They can also be connected to switches to manually send and receive data. Gunasekaran, Am not sure about what you are asking. Where are the input pins on the ic I would like to connect a potentiometer to the input on the ic for rc car.

So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. This oscillator can be used by connecting these two pins through a 1M Resistor.

But pins AD8-AD11 are not address pins, icc we have only 8 pins for address A0-A7, which can provide only different addresses, so this IC is not good for production? Frank Donald December 24, 59 Comments.

Simply put, HT12E converts the parallel inputs into serial output. So if you are working on a project which has to transmit a 4-bit data from ht12f end to other either by wire or wireless then this IC pair will be best suited for you. Supply voltage; 5V 2.

The query I raised about is dynamic uc i. Kindly repost your question. ULN was a transistor array IC used for driving high power devices.
