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

It is very important that your Decoder should also have this same address for them to talk datwsheet each other. What is Web Browser. Supply voltage; 5V 2. This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc.

Can range from 2. Submitted by admin on 30 October The input data code is decoded when no error or unmatched codes are found. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. TL — Programmable Reference Voltage. The IC has a built in oscillator. 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.


Found this item with same quality and at a lower price but prefer to buy from robokits. Thanks a lot for helping us to maintain competitive prices.

Daatsheet 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. If you want security you can connect any of the 8 pins to 5V to make it high. You can know to set up the HT12D after this from datashest.

Please submit the url of the better price you saw. 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 A7.

Connected to the Ground of circuit. The Encoded 12 bit output data obtained from HT12E ddatasheet to be given here. Arduino based GPS receiver.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

They can also be connected to switches to manually send and receive data. TL — Programmable Reference Voltage.

Customers who bought this product also purchased The IC is should be powered by 5V pin 18 datsaheet the ground pin pin 9 is grounded. Return and Refund Policy. These two ICs together form an Encoder and Decoder pair.

HT12D/HT12F – Product Details – Holtek

These are the 8-bit address bits, which is used to protect your data. Easy Interface with and RF or an Infrared transmission medium. A valid transmission ddatasheet indicated by a high signal at VT pin. Virgin Galactic — Commercial Space Flight. This pin powers the IC should use only 5V. Choosing Motor For Robots. If any valid data is received they can be obtained from these four pins.


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. So if you are working on a project which has to transmit a 4-bit data from one end to other either by dtasheet or wireless then this IC pair will be best suited for you. Mercury ball tilt switch 5mm dia. This pin has to be connected to Ground 0V to enable the Transmission. Easy to Use, Versatile Robotics Kits HT12D is a decoder integrated circuit that belongs to 2 dceoder series of decoders.

Can be used in Home automation for short range remote switching Safety systems like Burglar ht21d system, Smoke or Fire alarm system etc. We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product.

Full Name Email Address. They can also be connected to LED to physically view the received data.

Photograph just for reference. Interface SD Card with Arduino. SPI Module of Arduino. HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits.
