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.

HT12D Decoder IC

If you want security you can connect any of the 8 pins to 5V to make it high. 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. 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.

Virgin Galactic — Commercial Space Flight. 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. If any valid data is received they can be obtained from these four pins. They are paired with 2 12 series of encoders.

The IC is has a wide range of operating voltage from 2. This pin has to be connected to Ground 0V to enable the Transmission.


The data on 4 bit latch type output pins remain unchanged until new is received. Submitted by admin on 27 October Choosing Motor For Robots. These are the 8-bit address bits, which is used to protect your data.

This oscillator can be used by connecting these two pins through a 1M Resistor 17 Valid Transmission VT This pin will go high when a data is received. The Decoder receive the serial address and data from its corresponding decoder, transmitted dahasheet a carrier using an RF transmission medium and gives output to the output pins after processing the data. SPI Module of Arduino.

A valid transmission in indicated by a high signal at VT pin. Valid transmission; dataasheet high.

For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. It is mainly provided to interface RF and infrared circuits.

It is very important that your Decoder should also have this same address for them to talk to each other. You can know to set up the HT12D after this from here.

These two ICs together form an Encoder and Decoder pair. 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.

These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits.

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Easy to Use, Versatile Robotics Kits The serial input data is compared with the local addresses three times continuously.

The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded. Pull the Transmission Enable pin pin 14 dataeheet ground to activate transmission. Full Name Email Address. We should set the bits in same pattern on Encoder and Decoder IC to pair them. HT12D is a decoder integrated circuit that belongs to 2 12 series of decoders.


It is very important that your Decoder should have the same address of that of the encoder. We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product. 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.

Mercury ball tilt switch 5mm dia. Found this item with same quality and at a lower price but ht12r to buy from robokits. This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

TB Stepper Motor Driver 4. A basic connection diagram for the HT12E IC is shown decoxer In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Choosing Battery for Robots. We will notify you the result by email.

The primary function of HT12E is to encode a bit and send it out through the output pin.
