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.

Arduino based GPS receiver. The above diagram shows the practical set up of the HT12E encoder IC for better understanding on the working.

The Encoded 12 bit output data can be obtained from this pin. Simply put, HT12E converts the parallel inputs into serial output. 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?

Unk, Your address should be unique and only know to your receiver end to avoid other source signal interference.

Virgin Galactic — Commercial Space Flight. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. The query I raised about is dynamic addressing i. You can know to set up the HT12D after this from here. Ht122e basic connection ht12d 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.

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Supply voltage; 5V 2. It is mainly used in interfacing RF and infrared ht12d. Thank you for your reply. Dohab, To be honest this is entirely up to your requirement.


This high-density System-in-Package SiP integrates controller, power switches, and support components. In ht12d decoder section, i am changing the address by giving delay. Transmission enable; active low. They are paired with 2 12 series of decoders for use in remote control system applications. Interface GPS with Arduino. Pull the Transmission Enable pin pin 14 to ground to activate transmission.

HT12E has a transmission enable pin which is active low. And the output cycle will repeats based on the status of the TE pin in the IC. The IC has a built in oscillator. These 12 bits are divided into 8 address bits and 4 data bits.

If the TE pin retains the low signal the cycle repeats as long as the low signal in the TE pin exists. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. This cycle is repeated as long as TE is kept low. Gunasekaran, Am not sure about what you are asking.

Connected to the Ground of circuit. Submitted by admin on 30 October Can range from 2. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. As soon as TE returns to high, the encoder output completes its final cycle and then stops.

After receiving a low signal the HT12E starts the transmission of 4 data bits as shown in the timing diagram above. If you need more address I gt12e you to look for any other encoders and decoders with more address combinations. Using the address pins we can provide 8 bit security code for secured data transmission between the encoder and the decoder.

The following two tabs change content below. This pin has to be connected to Ground 0V to enable the Transmission. Skip to main content. HT12E starts working with a low signal on the TE ut12e. Thank you and I will let you know the working of the circuit. This oscillator can be used by connecting these two pins through a 1M Resistor. These are the 8-bit address bits, th12e is used to protect your data.


HT12E Encoder IC

Hope it is clear now. Choosing Motor For Robots. Regarding the addressing you can use a simple switch to feed your desired address.

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. Th12e, 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 hg12e 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.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. This data should be sent to the HT12D for decoding, it can either be sent directly through a wire or by using a wireless medium like RF or IR. Quote and Order boards in minutes on: Latest posts by Frank Donald see all. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.
