HT12E IC has four bit parallel data inputwhich it then converts to serial data output. This pin powers the IC should use only 5V. A basic circuit diagram for the HT12D 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.

For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. This site uses cookies. This IC hasmany applications in short range remote controlling. Basically found in applications of remote control systems.

HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders. It is mainly provided to interface RF and infrared circuits. The Encoded 12 bit output data obtained from HT12E has to be given here. SPI Module of Arduino. Connected to the Ground of circuit. Submitted by admin on 27 October Gone are the days when we used to use wires to connect two devices to establish a communication path. The IC has a built in oscillator. To know how a 4-bit data can be encoded and then send to the input pin of this IC, we have to understand the working of the HT12E Encoder IC which is given here.


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. By continuing to use this website, you agree to their use. Thus this helps in setting up oscillations in the IC. Choosing Battery for Robots.

This oscillator can be used by connecting these two pins through a 1M Datashete. Generally a resistor of value 51 KOhms can be used. Now first of all let me acquaint you about these two integrated circuits: If any valid data is received they can be obtained from these four pins.

What is Web Browser. Interface GPS with Arduino.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

This IC has a total of 18 pinsnine on either sides: These two ICs together form an Encoder and Decoder pair. Interface SD Card with Arduino. In additional to itit also has 8 address lines which can generally be grounded along with the pin number 9. This high-density System-in-Package SiP integrates controller, power switches, and support components. If you want security you can connect any of the 8 pins to 5V to make it high.

So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.

HT12D/HT12F – Product Details – Holtek

They are paired with 2 12 series of encoders. This oscillator can be used by connecting these two pins through a 1M Resistor 17 Valid Transmission VT This pin will go high when a data is received. They can also be connected to LED to physically view the received data. At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data.


HT12D Decoder IC

The 4-bit data that is received can be obtained on pins AD0 to AD1 and an address of 8-bit has to be set using the pins A0 to A7. Choosing Motor For Robots.

Used for interfacing RF circuits generally MegaHz. This is an CMOS logic integrated circuit encoder.

It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins. It is not mandatory to use it. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer. The input data code is decoded when no error or unmatched codes are found.

HT12D is capable of decoding 12 datasheef, of which 8 are address bits and 4 are data bits. Valid transmission; active high. The data on 4 bit latch type output pins remain unchanged until new is received.

The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded. Skip to main content. I am now datasheer to tell you about to control a certain robot wirelessly rather than using wires. An LED can also be connected across this terminal to indicate output. TL — Programmable Reference Voltage. 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 serial input data is compared with the local addresses three times continuously. We should set the bits in same pattern on Encoder and Decoder IC to pair them.
