HT12E Encoder IC can be used only with its pair HT12D. These two ICs together form an Encoder and Decoder pair. IC HT12D can be used only with its pair HT12E. These two ICs together form an Encoder and Decoder pair. They are bit. Robokits India HT12E & HT12D Encoder and Decoder IC for RF Modules [RKI- ] – The HT 12E Encoder ICs are HT12E Datasheet · HT12D Datasheet.

Found this item with same quality and at a lower price but prefer ut12e buy from robokits. HT12E has a transmission enable pin which is active low. HT12E is an encoder integrated circuit of 2 12 series of encoders.
HT12D/HT12F – Product Details – Holtek
The primary function of HT12E is to encode a bit and send it out through the output pin. 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. Virgin Galactic — Commercial Space Flight. It is very important that your Decoder should also have this same address for them to talk to each other.
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. Mercury ball tilt switch 5mm dia. Choosing Motor For Robots. Actual product may vary from the product photograph displayed above. Supply voltage; 5V 2. Submitted by admin on 27 October Easy to Use, Versatile Robotics Kits Please submit the url of the better price you saw.
For decoding a data the IC will requires an oscillatorluckily this IC has one in-built. TL — Programmable Reference Voltage. This oscillator can be used by connecting these two pins through a 1M Resistor.
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 datasueet IR.
They can also be connected to LED to physically view the received 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.
Can range from 2. 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.
In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. The IC is should be powered by 5V pin 18 and the ground pin pin 9 is grounded.
It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. TL — Programmable Reference Voltage.
HT12E Encoder IC
We will notify you the result by email. This high-density System-in-Package SiP integrates controller, power switches, and support components.
So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. This pin has to be connected to Ground 0V to enable the Transmission.
HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet
A basic circuit diagram for the HT12D IC is shown below In the above circuit I have set the 8-bit address data as dahasheet, by connecting all address pins to ground. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. They can also be connected to switches to manually send and receive data.
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. This pin powers the IC should use only 5V.
The Encoded 12 bit output data can be obtained from this nt12d. These are the 8-bit address bits, which is used to protect your data. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. We should set the bits in same pattern on Encoder and Decoder IC to pair them. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable.
These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. If you want security you can connect any of the 8 pins to 5V to make it high. Interface SD Card with Arduino. We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product.
