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.

Skip to content Gone are the days when we used to use wires to connect two devices to establish a communication path. Choosing Motor For Robots. Can range from 2.

This pin has to be connected to Ground 0V to enable the Transmission. Used for interfacing RF circuits generally MegaHz.

They are paired with 2 12 series of decoders for use in remote control system applications. Skip to main content. 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. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer.

HT12E Encoder IC

Thus this helps in setting up oscillations in the IC. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. Now first of all let me acquaint you about these two integrated circuits: This oscillator can be used by connecting these two datassheet through a 1M Resistor.


An LED can also be connected across this terminal to indicate output. 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.

For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. Interface SD Card with Arduino. If you want security you can connect any of the 8 pins to 5V to make it high.

HT12A/HT12E – Product Details – Holtek

These are the 8-bit address bits, which is used to protect your data. The IC has a built in oscillator.

You can know to set up the HT12D after this from here. The primary function of HT12E is to encode a bit and send it out through the output pin. So out of the bits 8-bits will be ht112e to set address and the remaining 4-bit will be used to transmit data.

Virgin Galactic — Commercial Space Flight. 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.

Simply put, HT12E converts the parallel inputs into serial output.

In additional to itit also has 8 address lines which can generally be grounded along with the pin number 9. Submitted by admin on 30 October 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. The IC is has a wide range of operating voltage from 2.


This high-density System-in-Package SiP integrates controller, power switches, and support components. It is mainly used in interfacing RF and infrared circuits. By continuing to use this website, you agree to their use. Gone are the days when we used to use wires to connect two devices to establish a communication path. 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.

These pins are generally shorted by a resistor. Generally a resistor of value 51 KOhms can be used. This IC hasmany applications in short range remote controlling. This site uses cookies. This cycle is repeated as long as TE is kept low. This IC has a total of 18 pinsnine on either sides: At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data.

The Encoded 12 bit output data can be obtained from this pin. Transmission enable; active low. 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. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. HT12E is an encoder integrated circuit of 2 12 series of encoders.
