Skip to main content. 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. This high-density System-in-Package SiP integrates controller, power switches, and support components. Interface GPS with Arduino.

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

HT12A/HT12E – Product Details – Holtek

Virgin Galactic — Commercial Space Flight. It is mainly used in interfacing RF and infrared circuits.

Interface SD Card with Arduino. The Encoded 12 bit output data can be obtained from this pin. These two ICs together form an Encoder and Decoder pair. This cycle is repeated as long as TE is kept low.


Connected to the Ground of circuit. Bt12e enable; active low. Submitted by admin on 30 October These 12 bits are divided into 8 address bits and 4 data bits. Simply put, HT12E converts the parallel inputs into serial output. 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.

Pull the Transmission Enable pin pin 14 to ground to activate transmission. SPI Module of Arduino.

This pin has to be connected to Ground 0V to enable the Transmission. Supply voltage; 5V 2. We should set the bits in same pattern on Encoder and Decoder IC to pair them. The IC has a built in oscillator. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.

These are the 8-bit address bits, which is used to protect your data.

The primary function of HT12E is to encode a bit and send it out through the output pin. You can know to set up the HT12D after this from here. It is very important that your Decoder should also have this same address for them to talk to each other. They can also be connected to switches to manually send and receive data.


In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Choosing Battery for Robots. They are paired with 2 12 series of decoders for use in remote control system applications. Can range from 2.

HT12E Encoder IC

What is Web Browser. 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 is an encoder integrated circuit of th12e 12 series of encoders. As soon as TE returns to high, the encoder output completes its final cycle and then stops.
