It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins.

This pin will go high when a data is received. This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc. Interface GPS with Arduino. TB Stepper Motor Driver 4. 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.

TL — Programmable Reference Voltage. Mercury ball tilt switch 5mm dia. Actual product may vary from the product photograph displayed above. Interface SD Card with Arduino. They can also be connected to LED to physically view the received data. Skip to main content. The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded.


We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product. This oscillator can be used by connecting these two pins decoddr a 1M Resistor.

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.

It is mainly provided to interface RF and infrared circuits. These two ICs together form an Encoder and Decoder pair. If you want security you can connect any of the 8 pins to 5V to make it high. The IC has a built in oscillator. Choosing Motor For Robots. For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. Return and Refund Policy. The input data code is hy12d when no error or unmatched codes are found.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

The serial input data is compared with the local addresses three times continuously. 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 Decoderr. Customers who bought this product also purchased Full Name Email Address. Supply voltage; 5V 2.


Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. A valid transmission in ddcoder by a high signal at VT pin. Easy to Use, Versatile Robotics Kits 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 Decoder IC

HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits. Virgin Galactic — Commercial Space Flight.

This high-density System-in-Package SiP integrates controller, power switches, and support components. This ICs are paired with each other. We will notify you the result by email. Choosing Battery for Robots. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.
