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: ✦

By continuing to use this website, you agree to their use. 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.

Submitted by admin on 30 October If you want security you can connect any of the 8 pins to 5V to make it high. 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. The encoded bit can be obtained from the Dout pin pin HT12E is an encoder integrated circuit of 2 12 series of encoders.


I am now going to tell you about to control a certain robot wirelessly rather than using wires. This high-density System-in-Package SiP integrates controller, power switches, and support components.

These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. SPI Module of Arduino. This IC hasmany applications in short range remote controlling.

Interface GPS with Arduino. 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 site uses cookies. Whenever an active low signal is applied at its TE pin then only the parallel data gets transferred serially at datasueet output, otherwise the IC is in high impedance state.

After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating dahasheet cycle of data transfer.

Skip to main content. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable.

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. We should set the bits in same pattern on Encoder and Decoder IC to pair them.


Choosing Motor For Robots. They are paired with 2 12 series of decoders for use in remote control system datazheet. This pin has to be connected to Ground 0V to enable the Transmission. These 12 bits are divided into 8 address bits and 4 data bits.

HT12E Encoder IC | HT12E Datasheet | Pin Diagram & Description

These are the 8-bit address bits, which is used to protect your data. Transmission enable; active low. 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. Arduino based GPS receiver.

It is mainly used in interfacing RF and infrared circuits. Basically found in applications of remote control systems.

Supply voltage; 5V 2.

HT12E Encoder IC

It is very important that your Decoder should also have this same address for them to talk to each other. What is Web Browser. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.

Connected to the Ground of circuit.
