HT12D DECODER DATASHEET PDF

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. For proper operation, a pair of encoder/decoder with the same number of Of this series, the HT12D is arranged to provide 8 address bits and 4 data bits, and. IC HT12D can be used only with its pair HT12E. These two ICs together form an Encoder and Decoder pair. They are bit.

So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. Submitted by admin on 27 October If any valid data is received they can be obtained from these four pins. Customers who bought this product also datasehet They are capable of Encoding 12 bit of information which consists of N address bits and N data bits.

Thanks a lot for helping us to maintain competitive prices. Skip to main datashdet. 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.

HT12D Decoder IC

Buy 15 or more pieces to get Free Shipping Option Availability: This oscillator can be used by connecting these two pins through a 1M Resistor. Submitted by admin on 30 October We should set the bits in same pattern on Encoder and Decoder IC to pair them.

A valid transmission in indicated by a high signal at VT pin. Arduino based GPS receiver.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

Easy Interface with and RF or an Infrared transmission medium. These two ICs together form an Encoder and Decoder pair. These two ICs together form an Encoder and Decoder pair. This pin powers the IC should use only 5V.

HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits. The IC has a built in oscillator. If you want security you can connect any of the 8 pins to 5V to make it high. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins. The primary function of HT12E is to encode a bit and send it out through the output datasheef. Choosing Battery for Robots. The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded.

We will notify you the result by email. The serial input data is compared with the local addresses three times continuously.

You can know to set up the HT12D after this from deckder. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. Choosing Motor For Robots. Please submit the url of the better price you saw.

HT12D/HT12F – Product Details – Holtek

Supply voltage; 5V 2. TL — Programmable Reference Voltage. In the above circuit I have set the 8-bit address data as 0b, by connecting all devoder pins to ground. The IC has a built in oscillator. Valid transmission; active high. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built.

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

They can also be connected to switches to manually send and receive data. 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.

Full Name Email Address. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. This ICs are paired with each other. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. The input data code is decoded when no error or unmatched codes are found. Interface GPS with Arduino.

The 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.
