HT12E begins a 4-word transmission cycle upon receipt of a transmission enable.

At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data. They are paired with 2 12 series of encoders.

HT12D Decoder IC

htt12e SPI Module of Arduino. TL — Programmable Reference Voltage. This high-density System-in-Package SiP integrates controller, power switches, and support components. This is an CMOS logic integrated circuit encoder. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.

The input data code is decoded when no error or unmatched codes are found.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

Basically found in applications of remote control systems. They are paired with 2 12 series of decoders for use in remote control system applications. What is Web Browser.

Choosing Motor For Robots. If you want security you can connect any of the 8 pins to ans to make it high. SPI Module of Arduino. This site uses cookies. This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc.

The encoded bit ratasheet be obtained from the Dout pin pin Skip to content Gone are the days when we used to use wires to connect two devices to establish a communication path. Choosing Motor Oof Robots. Connected to the Ground of circuit. This IC hasmany applications in short range remote controlling. Valid transmission; active high.

Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. HT12E has a transmission enable pin which is active low.

Now first of all let me acquaint you about these two h1t2d circuits: Virgin Galactic — Commercial Space Flight. Used for interfacing RF circuits generally MegaHz.

This cycle is repeated as long as TE is kept low. The data on 4 bit latch type output pins remain unchanged until new is ut12e. 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.

The Encoded 12 bit output data can be obtained from dataseet pin. It is mainly provided to interface RF and infrared circuits.

Pull the Transmission Enable pin pin 14 to ground to activate transmission. This IC has a total of 18 pinsnine on either sides: This pin has to be connected to Ground 0V to enable the Transmission.


After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer. Interface SD Card with Arduino. These are the 8-bit address bits, which is used to protect your data.

HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits. Skip to main content. 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.

Transmission enable; active low.

HT12E Encoder IC | HT12E Datasheet | Pin Diagram & Description

These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. HT12E IC has four bit parallel data inputwhich it then converts to serial data output. Arduino based GPS receiver. 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.

It is very important that your Decoder should also have this same address for them to talk to each other. This pin outputs the parallel data serially.
