Interface GPS with Arduino. Submitted by admin on inn October These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. 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. A basic connection diagram for the HT12E IC is shown below In ht21e above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.

HT12E Encoder IC | HT12E Datasheet | Pin Diagram & Description

It is mainly used in interfacing RF and infrared circuits. This oscillator can be used by connecting these two pins through a 1M Resistor.

You can know to set up the HT12D after this from here. The IC has a built in oscillator. So out of the bits 8-bits will be ij to set address and the remaining 4-bit will be used to transmit un. We should set the bits in same pattern on Encoder and Decoder IC to pair them. HT12E is an encoder integrated circuit of 2 12 series of encoders.


The encoded bit can be obtained from the Dout pin pin The IC is has a wide datqsheet of operating voltage from 2. 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 Battery for Robots. This cycle is repeated as long as TE is kept low.

HT12E Encoder IC

Arduino based GPS receiver. These two ICs together form an Encoder and Decoder pair.

Pull the Transmission Enable pin pin 14 to ground to activate transmission. They can also be connected to switches to manually send and receive data. SPI Module of Arduino. Simply put, HT12E converts the parallel inputs into serial output. In this image I have ht12w 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.

TL — Programmable Reference Voltage. Skip to main content. In the above circuit I have set the 8-bit address data as 0b, ht12ee connecting all address pins to ground. Virgin Galactic — Commercial Space Flight. Interface SD Card ddatasheet Arduino.

Connected to the Ground of circuit.

HT12E has a transmission enable pin which is active low. This high-density System-in-Package SiP integrates controller, power switches, and support components. What is Web Browser.

Supply voltage; 5V 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.


Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system ut12e. Can range from 2.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

The primary function of HT12E is to encode a bit and send it out through the output pin. This pin has to be connected to Ground 0V to enable the Transmission.

As soon as TE returns to high, the encoder output completes its final cycle and then stops. Choosing Motor For Robots. These 12 bits are divided into 8 address bits and 4 data bits. If you want security you can connect any of the 8 pins to 5V to make it high. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.

Transmission enable; active low. These are the 8-bit address bits, which is used to protect your data. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. They are paired with 2 12 series of decoders for use in remote control system applications.

It is very important that your Decoder should also have this same address for them to talk to each other. The Encoded 12 bit output data can be obtained from this datasgeet.
