HT12E Encoder IC

The Encoded 12 bit output data can be obtained from this pin. Arduino based GPS receiver. The encoded bit can be obtained from the Dout pin pin This oscillator can be used by connecting these two pins through a 1M Resistor. 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. As soon as TE returns to high, the encoder output completes its final cycle and then stops. Interface GPS with Arduino. Choosing Motor For Robots. Pull the Transmission Enable pin pin 14 to ground to activate transmission. This pin has to be connected to Ground 0V to enable the Transmission.

These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. The IC has a built in oscillator.

This cycle is repeated as long as TE is kept low. They are paired with 2 12 series of decoders for use in remote control system applications. Submitted by admin on 30 October HT12E has a transmission enable pin which is active low. Simply put, HT12E converts the parallel inputs into serial output. The IC is has a wide range of operating voltage 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.


The primary function of HT12E is to encode a bit and send it out through the output pin.

In if 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.

It is mainly used in interfacing RF and infrared circuits. Interface SD Card with Arduino. They can also be connected to switches to manually send and receive data.

HT12E is an encoder integrated circuit of 2 12 series of encoders. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. If you want security you can connect any of the 8 pins to 5V to make it high. Skip to main content. Choosing Battery for Robots. 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.

It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. 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.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

This high-density System-in-Package SiP integrates controller, power switches, and support components. Connected to the Ground of circuit. You can know to set up the HT12D after this from here. For decoding a data the IC will requires an oscillator, datsheet this IC has one in-built. These are the 8-bit address bits, which is used to protect your data. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.

SPI Module of Arduino. These two ICs together form an Encoder and Decoder pair. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.

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 datazheet of the HT12D decoder IC.
