HT12E DATASHEET PDF

HT12E Encoder IC can be used only with its pair HT12D. These two ICs together form an Encoder and Decoder pair. 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. The content and copyrights of the attached material are the property of its owner. Distributed by: ✦

HT12E has a transmission enable pin which is active low. Connected to the Ground of circuit. This pin outputs the parallel data serially. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable.

Whenever an active low signal is applied at its TE pin then only the parallel data gets transferred serially at the output, otherwise the IC is in high impedance state. Transmission enable; active low. These 12 bits are divided into jt12e address bits and 4 data bits.

After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer. It is mainly used in interfacing RF and infrared circuits. This pin has to be connected to Ground 0V to enable the Transmission.

These are the 8-bit address bits, which is used to protect your data. This cycle is repeated as long as TE is kept low. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Can range from 2. Simply put, HT12E converts the parallel inputs into serial output.

HT12E Encoder IC

This IC hasmany applications in short range remote controlling. It is very important that your Decoder should also have this same address for them to talk h1t2e each other. To find out more, including how to control cookies, see here: An LED can also be connected across this terminal to indicate satasheet. This IC has a total of 18 pinsnine xatasheet either sides: The primary function of HT12E is to encode a bit and send it out through the output pin.

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. HT12E is an encoder integrated circuit of 2 12 series of encoders. Choosing Battery for Robots. These pins are generally shorted by a resistor. Virgin Galactic — Commercial Space Flight. As soon as TE returns to high, the encoder output completes its final cycle and then stops.

This oscillator can be used by connecting these two pins through a 1M Resistor. Skip to content Gone are the days when we used to use wires to connect two devices to establish a communication path. If you want security you can connect any of the 8 pins to 5V to make it high.

The IC is has a wide range of operating voltage from 2. Gone are the days when datasneet used to use wires to connect two devices to establish a communication path. Pull the Transmission Enable pin pin 14 to ground to activate transmission.

You can know to set up the HT12D after this from here. Basically found in applications of remote control systems. Used for interfacing RF circuits generally MegaHz.
