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.

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

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

The data on 4 bit latch type output pins remain unchanged until new is received. Easy Interface with and RF or an Infrared transmission medium. They are paired with 2 12 xatasheet of encoders. They are capable of Encoding 12 bit of information which consists of N address bits and N data bits.

Interface SD Card with Arduino. They can also be connected to LED to physically view the received data.

This ICs are paired with each other. 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. Datssheet valid transmission in indicated by a high signal at VT pin. The Encoded 12 bit output data can be obtained from this pin.


Pull the Transmission Enable pin pin 14 to ground to activate transmission. If datashret valid data is received they can be obtained from these four pins. Ratasheet four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. Found this item with same quality and at a lower price but prefer to buy from robokits.

In simple terms, HT12D converts the serial input into parallel outputs. The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded. HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders.

They can also be connected to switches to manually send and receive data. 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. Interface GPS with Arduino.

HT12D Decoder IC

What is Web Browser. Skip to main content. Actual product may vary from the product photograph displayed above. So out of the bits datashete will be used to set address and the remaining 4-bit will be used to transmit data. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.


We should set the bits in same pattern on Encoder and Decoder IC to pair them. The input data code is decoded when no error or unmatched codes are found.

TL — Programmable Reference Voltage. This high-density System-in-Package SiP integrates controller, power switches, and support components. Can range from 2. Please submit the url of the better price you saw. Customers who bought this product also purchased 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.

The IC is has a wide range of operating voltage from 2.

Be the first to write a review. It is very important that your Decoder should have the same address of that of the encoder. You can know to set up the HT12D datasheeet this from here.
