It is very important that your Decoder should also have this same address for datawheet to talk to each other. These 12 bits are divided into 8 address bits and 4 data bits. These are the 8-bit address bits, which is used to protect your data.

HT12E Encoder IC

These two ICs together form an Encoder and Decoder pair. 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. HT12E is an encoder integrated circuit of 2 12 series of encoders. We should set the bits in same pattern on Encoder and Decoder IC to pair them.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

So if you datasbeet 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. This cycle is repeated as long as TE is kept low.


As soon as TE returns to high, the encoder output completes its final cycle and then stops. HT12E has a transmission enable pin which is active low. They are paired with 2 12 series of decoders for use in remote control system applications. Choosing Battery for Ht122e. 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.

Choosing Motor For Robots. Virgin Galactic — Commercial Space Flight. The primary function of HT12E ht122e to encode a bit and send it out through the output pin. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.


What is Web Browser. Arduino based GPS receiver. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. It is mainly used in interfacing RF and infrared circuits.

If you want security you can connect any of the 8 pins to 5V to make it high. Interface SD Card with Arduino. The Encoded 12 bit output data can be obtained from this pin.

They can also be connected to switches to manually send and receive data. You can know to set up the HT12D after this from here. TL — Programmable Reference Voltage.

It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Simply put, HT12E converts the parallel inputs into serial output. This high-density Eatasheet SiP integrates controller, power switches, and support components.


This oscillator can be used by connecting these two pins through a 1M Resistor. Connected to the Ground of circuit. 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 dafasheet of the HT12D decoder IC.

Skip to main content. The encoded bit can be obtained from the Dout pin pin Can range from 2. This pin has to be connected to Ground 0V to encodef the Transmission.

Pull the Transmission Enable pin pin 14 to ground to hh12e transmission. Submitted by admin on 30 October 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, ht12ee connecting all address pins to ground. 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.
