HT12E Encoder IC can be used only with its pair HT12D. These two ICs together form an Encoder and Decoder pair. The capa- bility to select a TE trigger on the HT12E or a. DATA trigger on the HT12A/B/C further en- hances the application flexibility of the 2. The content and copyrights of the attached material are the property of its owner. Distributed by: ✦

So out of the bits 8-bits will be used to set address htt12e the remaining 4-bit will be used to transmit data. Interface GPS with Arduino. Basically found in applications of remote control systems.

Thus this helps in setting up oscillations in the IC.

To find out more, including how to control cookies, see here: Transmission enable; active low. HT12E IC has four bit parallel data inputwhich it then converts to serial data output. This cycle is repeated as long as TE is kept low. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. Now first of all let me acquaint you about these two integrated circuits: It is mainly used in interfacing RF and infrared circuits. This pin outputs the parallel data serially.

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. This is an CMOS logic integrated circuit encoder. HT12E is an encoder integrated circuit of 2 12 series of encoders. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.


Used for interfacing RF circuits generally MegaHz. An LED can also be connected across this terminal to indicate output. The IC is has a wide range of operating voltage from 2. At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data. Gone are the days when we used to use wires to connect two devices to establish a communication path. SPI Module of Arduino. This high-density System-in-Package SiP integrates controller, power switches, and support components.

It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.

ht12e ht12d datasheet – ht12e ht12d datasheet

Skip to content Gone are the days when ht12ee used to use wires to connect two devices to establish a communication path. This site uses cookies. TL — Programmable Reference Voltage. If you want security you can connect any of the 8 pins to 5V to make it high.

HT12E has a transmission enable pin which is active low. These two ICs together form an Encoder and Decoder pair.

HT12E Encoder IC | HT12E Datasheet | Pin Diagram & Description

These pins are generally shorted by a resistor. These 12 bits are divided into 8 address bits and 4 data bits. 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.

This IC hasmany applications in short range remote controlling.

HT12E Encoder IC

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. Interface SD Card with Arduino. This IC has a total of 18 pinsnine on either sides: Generally a resistor of value 51 KOhms can be used.


You can know to set up the HT12D after this from here. What is Web Browser. This pin has to be connected to Ground 0V to enable the Transmission.

Supply voltage; 5V 2. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. These are the 8-bit address bits, which is used to protect your data. Choosing Battery for Robots. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer.

As soon as TE returns to high, the encoder output completes its final cycle and then stops. The 4-bit data that has to be sent has daasheet be given to the pins AD0 to AD1 and an address of 8-bit has to be set using the pins A0 to A7. Virgin Galactic — Commercial Space Flight.

The encoded bit can be obtained from the Dout pin pin By continuing to use this website, you agree to their use. HT12E ht12 a 4-word transmission cycle upon receipt of a transmission enable. Arduino based GPS receiver. We should set the bits in same pattern on Encoder and Decoder IC to pair them. They are paired with 2 12 series of decoders for use in remote control system applications.
