HT12A/HT12E – Product Details – Holtek
These two ICs together form an Encoder and Decoder pair. 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. 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.
Datasheef high-density System-in-Package SiP integrates controller, power switches, and support components. Arduino based GPS receiver.
HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. HT12E is hf12e encoder integrated circuit of 2 12 series of encoders.
We should set the bits in same pattern on Encoder and Ht1e2 IC to pair them. 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. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. Pull the Transmission Enable pin pin 14 to ground datasheef activate transmission. This pin has to be connected to Ground 0V to enable the Transmission.
As soon as TE returns to high, the encoder output completes its final cycle and then stops.
The primary function of HT12E is to encode a bit and send it out through the output pin. A basic connection diagram for the HT12E 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.
The IC is has a wide range of operating voltage from 2. The encoded bit can be obtained from the Dout h1t2e pin This cycle is repeated as long as TE is kept low. SPI Module of Arduino. They can also be connected to switches to manually send and receive data. This oscillator can be used by connecting these two datsheet through a 1M Resistor.
What datasheef Web Browser. The IC has a built in oscillator.
Choosing Motor For Robots. Interface GPS with Arduino. If you want security you can connect any of the 8 pins to 5V to make it high.
HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet
It is very important that your Decoder should also have this same address for them to talk to each other. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data. These 12 bits are divided into 8 address bits and 4 data bits. They are paired with 2 12 series of decoders for use in remote control system applications.
It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. Connected to the Ground of circuit.
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. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.
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. The Encoded 12 bit output data can be obtained from this pin. You can know to set up the HT12D after this from here.
HT12E Encoder IC
Can range from 2. It is mainly used in interfacing RF and infrared circuits. These are datashret 8-bit address bits, which is used to protect your data.
HT12E has a transmission enable pin which is active low. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.
