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.

If you want security you can connect any of the 8 pins to 5V to make it high. A valid transmission in indicated by a high signal at VT pin.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

By continuing to use this website, you agree to their use. 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.

At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data. In simple terms, HT12D converts the serial input into parallel outputs. 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.


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

To find out more, including how to control cookies, see here: Connected to the Ground of circuit. HT12E IC has four bit parallel data inputwhich it then converts to serial data output. Transmission enable; active low. In additional to itit also has 8 address lines which can generally be grounded along with the pin number 9.

Choosing Battery for Robots. An LED can also be connected across this terminal to indicate output.

These are the 8-bit address bits, which is used to protect your data. This high-density System-in-Package SiP integrates controller, power switches, and support components.

What is Web Browser. In the above circuit I have set vatasheet 8-bit address data as 0b, by connecting all address pins to ground.

Interface GPS with Arduino. SPI Module of Arduino. The Encoded 12 bit output data can be obtained from this pin. This IC hasmany applications in short range remote controlling. The IC is has a wide range of operating voltage from 2. The IC has a built in oscillator. Skip to content Gone are the days when we used to use wires to connect two devices to establish a communication path. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.

HT12D Decoder IC

Arduino based GPS receiver. The input data code is decoded when no error or unmatched codes are found. Supply voltage; 5V 2. It is mainly provided to interface RF and infrared circuits.

Now first of all let me acquaint you about these two vatasheet circuits: I am now going to tell you about to control a certain robot wirelessly rather than using wires. The serial input data is compared daatsheet the local addresses three times continuously. They are paired with 2 12 series of decoders for use in remote control system applications.


Datasheet 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. Gone are the days when we used to use wires to connect two devices to establish a communication path. The data on 4 bit latch type output pins remain unchanged until new is received.

These two ICs together form an Encoder and Decoder pair. SPI Module of Arduino.

Valid transmission; active high. Supply voltage; 5V 2. Interface SD Card with Arduino. Generally a resistor of value 51 KOhms can be used. Submitted by admin on 30 October Interface SD Card with Arduino. This site uses dayasheet. These pins are generally shorted by a resistor. This is an CMOS logic integrated circuit encoder.

This IC has a total of 18 pinsnine on either sides: Can be used in Home automation for short range remote switching Safety systems datashet Burglar alarm system, Smoke or Fire alarm system etc.

As soon as TE returns to high, the encoder output completes its final cycle and then stops. Choosing Motor For Robots. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins.

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.
