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.

Dohab, To be honest this is entirely up to your requirement. Frank Donald December 24, 59 Comments. If you want security you can connect any of the 8 pins to 5V to make it high. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. Connected to the Ground of circuit. The encoder and decoder should use the same address and data format.

Regarding the addressing you can use a simple switch to feed your desired address. Notify of all new follow-up comments Notify of new replies to all my comments. Dear Frank Thank you for your reply. Hii Frank, I am interfacing 4 encoder with htt12e address configuration. If you need more address I suggest you to look for any other encoders and decoders with more address combinations.

No mechanical switching involved.

Gunasekaran, Am not sure about what you are asking. There is no use of that IC here. This pin has to be connected to Ground 0V to enable the Transmission. 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?

Choosing Motor For Robots. The query I raised about is dynamic addressing i. These two ICs together form an Encoder and Decoder pair. Latest posts by Frank Donald see all. But now, if i want to connect more than 4 encoder how do i configure data pins? The Encoded 12 bit output data can be obtained from this pin. Skip to main content. However if you need to have more address combinations then you might want to look for other encoder-decoder pair available in the market. In this image I ix 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 oc will be reflected on the output side of the HT12D decoder IC.

Hope it is clear now. Choosing Battery for Robots. SSS, As per the datasheet you need that resistor to kick start ht21e internal oscillator in the chip which in turn feeds clock pulse to data transmission.

HT12E is an encoder integrated circuit of 2 12 series of encoders. In ht12d decoder section, i am changing the address by giving delay.

They are paired with 2 12 series of decoders for use in remote control system applications. These are the 8-bit address bits, which is used to protect your data. The encoded bit can be obtained from the Dout pin pin Interface GPS ht12s Arduino. 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 Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

Calculating addresses, we are limited to 56 addresses per pair. ULN was a transistor array IC used for driving high power devices.

But if i want to transmit lc in 5th encoder, in which pin of encoder sholud i provide data to encoder??? Pull the Transmission Enable pin pin 14 to ground to activate transmission. The encoder Hg12e will be in standby mode if the TE pin is disabled and thus the status of this pin was necessary for encoding process. TL — Programmable Reference Voltage. Thank you for the reply and clarification.

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

Where are the input pins on the lc I would like to connect a potentiometer to the input on the ic for rc car. You can know to set up the HT12D after this from here. Virgin Galactic — Commercial Space Flight. 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. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits.

These 12 bits are divided into 8 address bits and 4 data bits.

The above diagram shows the practical set up of the HT12E encoder IC for better understanding on the working. Request hg12e idea on this.

HT12E Encoder IC

The IC has a built in oscillator. Arduino based GPS receiver. I have 5v 12d cut and 12v 12e ckt.
