Simply put, HT12E converts the parallel inputs into serial output. The IC is has a wide range of operating voltage from 2.

For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. Transmission enable; active low. Interface SD Card with Arduino. 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.

HT12E is an encoder integrated circuit of 2 12 series of encoders. This pin outputs the parallel data serially. Virgin Galactic — Commercial Space Flight. 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.

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. Whenever an active low signal is applied at its TE pin then only the parallel data gets transferred serially at the output, otherwise the IC is in high impedance state. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.


These 12 bits are divided into 8 address bits and 4 data bits.

HT12E Encoder IC

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. SPI Module of Arduino.

Now first of all let me acquaint you about these two integrated circuits: Connected to the Ground of circuit. Skip to content Gone are the days when we used to use wires to connect two devices to establish a communication path. Supply voltage; 5V 2. HT12E has a transmission enable pin which is active low. Arduino based GPS receiver. The primary function of HT12E is to encode a bit and send it out through the output pin.

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.

The Encoded 12 bit ov data can be obtained from this pin. By continuing to use this website, you agree to their use. These are the 8-bit address bits, which is used to protect your data. If you want security datashheet can connect any of the 8 pins to 5V to make it high. Used for interfacing RF circuits generally MegaHz. I am now going to tell you about to control a certain robot wirelessly rather than using wires.

Thus this helps in setting up oscillations in the IC. This is an CMOS logic integrated circuit encoder. They are paired with 2 12 series of decoders for use in remote control system applications.

What is Web Browser.

To find out more, including how to control cookies, see here: HT12E IC has four bit parallel data inputwhich it then converts to serial data output. It encodes the 12 bit parallel data into dataaheet for transmission through an RF transmitter.

In additional to itit also has 8 address lines which can generally be grounded along with the pin number 9.

Pull the Transmission Enable pin pin 14 to ground to activate ht2e. This site uses cookies. This cycle is repeated as long as TE is kept low. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer.
