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.

These two ICs together form an Encoder and Decoder pair.
Thanks a lot for helping us to maintain competitive prices. This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc.
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. It is not mandatory to use it. You can know to set up the HT12D after this from here.
The primary function of HT12E is to encode a bit and send it out through the output pin. This high-density System-in-Package SiP integrates controller, power switches, and support components. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. It is very important that your Decoder should have the same address of that of the encoder. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.
These are the 8-bit address bits, which is used to protect your data. 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.
HT12D/HT12F – Product Details – Holtek
If you want security you can connect any of the 8 pins to 5V to make it high. It is mainly provided to interface RF and infrared circuits.
So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.
These are the 8-bit address bits, datashwet is used to protect your data. In simple terms, HT12D converts the serial input into parallel outputs. The data on 4 bit latch type output pins remain unchanged until new is received. Return and Refund Policy. SPI Module of Arduino. 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. Interface GPS with Arduino.
HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet
The IC has a built in oscillator. The encoded bit can be obtained from the Dout pin pin The Encoded 12 bit output data obtained from HT12E has to be given here. Submitted by admin on 27 October So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. Choosing Battery for Robots. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.
Interface SD Card with Arduino. They can also be connected to LED to physically view the received data. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins.
HT12D Decoder IC
Actual product may vary from the product photograph displayed above. This data should be sent to the HT12D for decoding, it can either be sent directly through a wire or by using a wireless decofer like RF or IR. We should set the bits in same pattern on Encoder and Decoder IC to pair them.
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, hr12d we can make any changes on these 4-bits and they will be reflected on the output side of the HT12D decoder IC.
This oscillator can be used by connecting these two pins through a 1M Resistor ddecoder Valid Transmission VT This pin will go high when a data is received. The IC is has a wide range of operating voltage from 2. The serial input data is compared with the local addresses three times continuously.
Arduino based GPS receiver. Skip to main content. Can range from 2.
This oscillator can be used by connecting these two pins through a 1M Resistor. TL — Programmable Reference Voltage. If any valid data is received they can be obtained from these four pins. The IC has a built in oscillator. The input data code is decoded when no error or unmatched codes are found. HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders.
