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.

Be the first to write a review. A valid transmission in indicated by a high signal at VT pin.

They can also be connected to LED to physically view the received data. TL — Programmable Reference Voltage. The IC has a built in oscillator. In simple terms, HT12D converts the serial input into parallel outputs.

HT12D Decoder IC

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 Motor For Robots. This oscillator can be used by connecting these two pins through a 1M Resistor. What is Web Browser. These two ICs together form an Encoder and Decoder pair. Actual product may vary from the product photograph displayed above.

Submitted by admin on 27 October Arduino based GPS receiver. These two ICs together form an Encoder and Decoder pair. The data on 4 bit latch type output pins remain unchanged decooder new is received. 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 is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits. The IC is has a wide range of operating voltage from 2.


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 datashewt can make datashet changes on these 4-bits and they will be reflected on the output side of the HT12D decoder IC. Found this item with same quality and at a lower price but prefer to buy from robokits.

Connected to the Ground of circuit.

Dataxheet the Transmission Enable pin pin 14 to ground to activate transmission. The Decoder receive the serial address and data from its corresponding decoder, transmitted by a carrier using an RF transmission medium and gives output to the output pins after processing the data. 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.

Choosing Battery for Robots. They are paired with 2 12 series of encoders.

HT12D Decoder IC | HT12D Datasheet | Pin Diagram

Supply datasheeet 5V 2. If you want security you can connect any of the 8 pins to 5V to make it high. This ICs are paired with each other.

This data should be sent to the HT12D for decoding, it can either be sent directly through a wire or by using a wireless medium like RF or IR. They can also be connected to switches to manually send and receive data. We should set the ht12f in same pattern on Encoder and Decoder IC to pair them. This pin powers the IC should use only 5V. 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.


HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

The encoded bit can be obtained from the Dout pin pin Interface SD Card with Arduino. This pin will go high when a data is received. The Encoded 12 bit output data obtained from HT12E has to be given here.

TL — Programmable Reference Voltage. The Datasheeet has a built in oscillator. The IC dataxheet should be powered by 5V pin 18 and the ground pin pin 9 is grounded. These are the 8-bit address bits, which is used to protect your data.

Valid transmission; active high. 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.

This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc. Submitted by admin on 30 October Thanks decder lot for helping us to maintain competitive prices. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Photograph just for reference. Can range from 2. We should set the bits in same pattern on Encoder and Decodet IC to pair them.

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