HT12D Decoder IC

What is Web Browser. 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. HT12D is a decoder integrated circuit that belongs to datasneet 12 series of decoders. An LED can also be connected across this terminal to indicate output. Generally a resistor of value 51 KOhms can be used.

SPI Module h12d Arduino. By continuing to use this website, you agree to their use. The data on 4 bit latch type output pins remain unchanged until new is received. 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. We should set the bits in same pattern on Encoder and Decoder IC to pair them. At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data.

Supply voltage; 5V 2. This IC has a total of 18 pinsnine on either sides: Datashfet first of all let me acquaint you about these two integrated circuits: For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. To find out more, including how to control cookies, see here: They are paired with 2 12 series of encoders.


Datashet found in applications of remote control systems.

TL — Programmable Reference Voltage. The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded. In simple terms, HT12D converts the serial input into parallel outputs. This oscillator can be used by connecting these two pins through a 1M Resistor. Submitted by admin on 27 October These two ICs together form an Encoder and Decoder pair. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer.

The Encoded 12 bit output data obtained from HT12E has to be given here. Used for interfacing RF circuits generally MegaHz. Virgin Galactic — Hr12d Space Flight. HT12D is capable of decoding 12 bits, vatasheet which 8 are address bits and 4 are data bits. A valid transmission in indicated by a high signal at VT pin. These pins are generally shorted by a resistor.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

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

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. This is an CMOS logic integrated circuit encoder. Thus this helps in setting up oscillations in the IC. This od uses cookies.

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. HT12E IC has four bit parallel data input off, which it then converts to serial data output.


It is mainly provided to interface RF and infrared circuits. 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.

Choosing Motor For Robots. The input data code is decoded when no error or unmatched codes are found.

This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc. This IC hasmany applications in short range remote controlling.

ht12e ht12d datasheet – ht12e ht12d datasheet

I am now going to tell you about to control a certain robot wirelessly rather than using wires. The serial input data datasheet compared with the local addresses three times continuously.

Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.

Choosing Battery for Robots. In additional to itit also has 8 address lines which can generally be grounded along with the pin number 9. It is very important that your Decoder should have the same address of that of the encoder. If any valid data is received they can be obtained from these four pins.

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.
