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 Datasheet

HT12E IC has four bit parallel data inputwhich it then converts to serial data output. This pin outputs the parallel data serially.

This high-density System-in-Package SiP integrates controller, power switches, and support components. Ht21e 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.

This is an CMOS logic integrated circuit encoder.

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 ht12r 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. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.

SPI Module of Arduino. Connected to the Ground of circuit. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. It is mainly used in interfacing RF and infrared circuits. Used for interfacing RF circuits generally MegaHz.

Interface GPS with Arduino. Generally a resistor of value 51 KOhms can be used. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Simply put, HT12E converts the parallel inputs into serial output. HT12E has a transmission enable pin which is active low. To find out more, including how to control cookies, see here: Thus this helps in setting up oscillations in the IC.

You can know to set up the HT12D after this from here. At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.

Interface SD Card with Arduino. 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. TL — Programmable Reference Voltage. Pull the Transmission Enable pin pin 14 to ground to activate transmission. 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.

If you want security you can connect any of the 8 pins to 5V to make it high.

HT12E Encoder IC

This IC has a total of 18 pinsnine on either sides: Now first of all let me acquaint you about these two integrated circuits: These are the 8-bit address bits, which is used to protect your data. By continuing to use this datadheet, you agree to their use. 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 oscillator can be used by connecting these two pins through a 1M Resistor.

This pin has to be connected to Ground 0V to enable the Transmission. The IC has a built in oscillator.

An LED can also be connected across this terminal to indicate output. This IC hasmany applications in short range remote controlling. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer.

Gone are the days when we used to use wires to connect two devices to establish a communication path.
