The primary function of HT12E is to encode a bit and send it out through the output pin. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

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. It is mainly used in interfacing RF and infrared circuits. The Encoded 12 bit output data can be obtained from this pin. What is Web Browser. SPI Module of Arduino.

These four pins are datasheft to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. Arduino based GPS receiver. As soon as TE returns to high, the encoder output completes its final cycle and then stops.

Choosing Motor For Robots.

Simply put, HT12E converts the parallel inputs into serial output. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.

For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.

Interface GPS with Arduino. 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 Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Choosing Battery for Robots.

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

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. Virgin Galactic — Commercial Space Flight. HT12E has a transmission enable pin which is active low.

These 12 bits are divided into 8 address bits and 4 data bits. This high-density System-in-Package SiP integrates controller, vatasheet switches, and support components. These are the 8-bit address bits, which is used to protect your data. HT12E is an encoder integrated circuit of 2 12 series of encoders. They can also be connected to switches to manually send and receive data.

Transmission enable; active low.

HT12E Datasheet

Supply voltage; 5V 2. This pin has to be connected to Ground 0V to enable the Transmission. The IC is has a wide range of operating voltage from 2. Skip to main content. These two ICs together form an Encoder and Decoder pair.

HT12E Encoder IC

They are paired with 2 12 series of decoders for use in remote control system applications. If you want security you can connect any of the 8 pins to 5V to make it high. 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.

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. TL — Programmable Reference Voltage. The IC has a built in oscillator.

Interface SD Card with Arduino. The encoded bit can be obtained from the Dout pin pin It is very important that your Decoder should also have this same address for them to talk to each other.

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