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: ✦

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

These two ICs together form an Encoder and Decoder pair. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.

To find out more, including how to control cookies, see here: An LED can also be connected across this terminal to indicate output. This IC has a total of 18 pinsnine on either sides: You can know to set up the HT12D after this from here.

They are paired with 2 12 series of decoders for use in remote control system applications. What is Web Browser.

Choosing Battery for Robots. 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 oscillator can be used by connecting these two pins through a 1M Resistor.

HT12E IC has four bit parallel data inputwhich it then converts to serial data output. Datashert IC is has a wide range of operating voltage from 2.

HT12E Encoder IC

Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Transmission enable; active low. It is mainly used in interfacing RF and infrared circuits.

This site uses cookies. 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. This cycle is repeated as long as TE is kept low. The Encoded 12 bit output data can be obtained from this pin.

The IC has a built in oscillator. As soon as TE returns to high, the encoder output completes its final cycle and then stops. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.


Connected to the Ground of circuit. Can range from 2.

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. They can also be connected to datxsheet to manually send and receive data. Now first of all let me acquaint you about these two integrated circuits: Interface SD Card with Arduino. HT12E darasheet an encoder integrated circuit of 2 12 series of encoders.

The encoded bit can be obtained from the Dout pin pin These are the 8-bit address bits, which is used to protect your data.

Used for interfacing RF circuits generally MegaHz. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.

Supply voltage; 5V 2.

HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. 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.
