Can range from 2. It is very important that your Decoder should also have this same address for them to talk to each other. This oscillator can be used by connecting these two pins through a 1M Resistor. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.

The IC has a built in oscillator. 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. Simply put, HT12E converts the parallel inputs into serial output. Pull the Transmission Enable pin pin 14 to ground to activate transmission. Skip to main content.


Interface SD Card with Arduino. Connected to the Ground of circuit.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

Supply voltage; 5V 2. SPI Module of Arduino. 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. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits.

If you want security you can connect any of the 8 pins to 5V to make it high. These two ICs together form an Encoder and Decoder pair.

HT12E Encoder IC

It is mainly used in interfacing RF and infrared circuits. This pin has to be connected to Ground 0V to enable the Transmission. HT12E has a transmission enable pin which is active low.

The Encoded 12 bit output data can be obtained from this pin. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable.

Submitted by admin on 30 October Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Choosing Motor For Robots. This cycle is repeated as long as TE is kept low. You can know to set up the HT12D after this from here. The primary function of HT12E is to encode a bit and send it out through the output pin.


As soon as TE returns to high, the encoder output completes its final cycle and then stops. TL — Programmable Reference Voltage.

HT12E Encoder IC | HT12E Datasheet | Pin Diagram & Description

The encoded bit can be obtained from the Dout pin pin They can also be connected to switches to manually send and receive data. Interface GPS with Arduino. These are the 8-bit address bits, which is used to protect your ht2e. So if you are working on a project which has to transmit a 4-bit enckder from one end to other either by wire or wireless then this IC pair will be best suited for you. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.

Choosing Battery for Robots. The IC is has a wide range of operating voltage from 2. What is Web Browser. Transmission enable; active low.

So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.
