HT12D 2 12 Series of Decoders Features. Operating voltage: V~12V Low power and high noise immunity CMOS Built-in oscillator needs only 5% resistor. IC HT12D can be used only with its pair HT12E. These two ICs together form an Encoder and Decoder pair. They are bit. HT12D Datasheet, HT12D Holtek Decoder Datasheet, buy HT12D Decoder IC.

For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. This high-density System-in-Package SiP integrates controller, power switches, and support datashwet. Skip to main content. What is Web Browser.
HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits. TL — Programmable Reference Voltage.
It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins. In the above circuit I have set the 8-bit eatasheet data as 0b, by connecting all address pins to ground.
The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded. Valid transmission; active high. We should set the bits in same pattern on Encoder and Decoder IC to pair them. A basic circuit diagram for the HT12D IC is shown below In the above circuit I have set the 8-bit address data as yt12d, by connecting all address pins to ground.
So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. Virgin Galactic — Commercial Satasheet Flight. This oscillator can be used by connecting these two pins through a 1M Resistor.
These are the 8-bit address bits, which is used to protect your data. Supply voltage; 5V 2. A valid transmission in indicated by a high signal at VT pin. Arduino based GPS receiver.
HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders. 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.
HT12D Decoder IC
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. Submitted by admin on 27 October If any valid data is received they can be obtained from these four pins.
It is not mandatory to use it. 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.

This pin powers the IC should use only 5V. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Darasheet is mainly provided to interface RF and infrared circuits.
They can also be connected to LED to physically view the received data. They are paired with 2 12 series of encoders. The input data code is decoded when no error or unmatched codes are found. SPI Module of Arduino. It is very important that your Decoder should have the same address of that of the encoder.
The Encoded 12 bit output data obtained from HT12E has to be given here. Connected to the Ground of circuit. In simple terms, HT12D converts the serial input into parallel outputs. 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. Choosing Battery for Robots. The IC has a built in oscillator.
The serial input data is compared with the local addresses three times continuously. These two ICs together form datasheeet Encoder and Decoder pair. This pin will go high when a data is received. The data on 4 bit latch type output pins remain unchanged until new is received. If you want security you can connect ht12x of the 8 pins to 5V to make it high.
