HT12E is a series encoder IC (Integrated Circuit) for remote control applications. It is commonly used for radio frequency (RF) applications. By using the. HT12E Datasheet, HT12E Holtek Encoder Datasheet, buy HT12E Encoder IC. The capa- bility to select a TE trigger on the HT12E or a. DATA trigger on the HT12A/B/C further en- hances the application flexibility of the 2.
HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. They can also be connected to switches to manually send and receive data. Supply voltage; 5V 2. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits.
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. HT12E has a transmission enable pin which is active low. This high-density System-in-Package SiP integrates controller, power switches, and support components.
For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. The IC has a built in datashet. It is mainly used in interfacing RF and infrared circuits.
The encoded bit can be obtained from the Dout pin pin The Encoded 12 bit output data can be obtained from this pin. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. These two ICs together form an Encoder and Decoder pair. Virgin Galactic — Commercial Space Flight.
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. SPI Module of Arduino. Transmission enable; active low. If you want security you can connect any of the 8 pins to 5V to make it high. Simply put, HT12E converts the parallel inputs into serial output. Interface GPS with Arduino. They are paired with 2 12 series of decoders for use in remote control system applications. The primary function of HT12E is to encode a bit and send it out through the output pin.
These are the 8-bit address bits, which is used to protect your data. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. This cycle is repeated as long as TE is kept low.
Choosing Motor For Robots. HT12E is an encoder integrated circuit of 2 12 series of encoders. TL — Programmable Reference Voltage. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.
Choosing Battery for Robots. In this image I have made all four data bits as zero lowwhen ratasheet 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.
We should set the bits in same pattern on Encoder and Decoder IC to pair them. You can know to set up the HT12D after this from here. This oscillator can be used by connecting these two pins through a 1M Resistor.
The IC datadheet has a wide range of operating voltage from 2.
HT12E Encoder IC
Pull the Transmission Enable pin pin 14 to ground to activate transmission. 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. Interface SD Card with Arduino. As soon as TE returns to high, the encoder output completes its final cycle and then stops.
Skip to main content. It is very important that your Decoder should also have this same address for them to talk to each other. Connected to the Ground of circuit.
