HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

An LED can also be connected across this terminal to indicate output. This IC hasmany applications in short range remote controlling. Please submit the url of the better price you saw.

It is very important that your Decoder datashert also have this same address for them to talk to each other. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.

Skip to content Gone are the days when we used to use wires to connect two devices to establish a communication path. Found this item with same quality and at a lower price but prefer to buy from robokits.

Supply voltage; ht12s 2.

Buy 15 or more pieces to get Free Shipping Option Availability: Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Pull the Transmission Enable pin pin 14 to ground to activate 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 begins a 4-word transmission cycle upon receipt of a transmission enable. By continuing to use this website, you agree to their use. What is Web Browser. This IC has a total of 18 pinsnine on either sides: Full Name Email Address.

In this image I have made all four data bits as zero lowwhen this is decoded we datxsheet get the same kind of bits on the output side of HT12D, similarly we can make any changes on these ddatasheet and they will be reflected on the output side of the HT12D decoder IC.

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. Photograph just for reference.

HT12E Encoder IC

It ut12e mainly used in interfacing RF and infrared circuits. 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. This ICs are paired with each other.

If you want security you can connect any of the 8 pins ht2d 5V to make it high. 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 ajd to ground. 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.

Easy Interface with and RF or an Infrared transmission medium. These 12 bits are divided into 8 jt12e bits and 4 data bits. The Encoded 12 bit output data can be obtained from this pin. HT12E is an encoder integrated circuit of 2 12 series of encoders.


These two ICs together form an Encoder and Decoder pair. Arduino based GPS receiver. This high-density System-in-Package SiP integrates controller, power switches, and support components.

HT12E has a transmission enable pin which is active low. They are paired with 2 12 series of decoders for use in remote control system applications. Transmission enable; active low. Be the first to write a review. Mercury ball tilt switch 5mm dia. Now first of all let me acquaint you about these two integrated circuits: Thus this helps in setting up oscillations in the IC.

The Decoder receive the serial address and data from its corresponding decoder, transmitted by a carrier using an RF transmission medium and gives output to the output pins after processing the data.

Interface SD Card with Arduino. We should set the bits in same pattern on Encoder and Decoder IC to pair them. You can know to set up the HT12D after this from here. Virgin Galactic — Commercial Space Flight. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. This is an CMOS logic integrated circuit encoder. They can also be connected to switches to manually send and receive data. As soon as TE returns to high, the encoder output completes its datasbeet cycle and then stops.
