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: ✦

This IC has a total of 18 pins ddatasheet, nine on either sides: If you want security you can connect any of the 8 pins to 5V to make it high. This is an CMOS logic integrated circuit encoder. 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.

HT12E Encoder IC

Virgin Galactic — Commercial Space Flight. The Encoded 12 bit output data can be obtained from this pin. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. Interface SD Card with Arduino. Simply put, HT12E converts the parallel inputs into serial output. This high-density System-in-Package SiP integrates controller, power switches, and support components.

At low signal data is transferred via antenna and received by Receiver IC which then decodes it to original parallel data. Submitted by admin on 30 October It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.


HT12E Datasheet(PDF) – Holtek Semiconductor Inc

You can know to set up the HT12D after this from here. The IC is has a wide range of operating voltage from 2. dattasheet

Generally a resistor of value 51 KOhms can be used. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. Skip to content Gone are the days when we used to use datwsheet to connect two devices to establish a communication path. This cycle is repeated as long as TE is kept low.

Connected to the Ground of circuit. So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.

Now first of all let me acquaint you about these two integrated circuits: The encoded bit can be obtained from the Dout pin pin These two ICs together form an Encoder and Decoder pair. Used for interfacing RF circuits generally MegaHz. 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. As soon as TE returns to high, the encoder output completes its final datasgeet and then stops.


To find out more, including how to control cookies, see here: They can also be connected to switches to manually send and receive data.

Supply voltage; 5V 2. In the ht12d circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.

ht12e ht12d datasheet – ht12e ht12d datasheet

In this image I have made hr12e 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 jt12e any changes on these 4-bits and they will be reflected on the output side of the HT12D decoder IC.

This oscillator can be used by connecting these two pins through a 1M Resistor. The IC has a built in oscillator. These are the 8-bit address bits, which is used to protect your data.

SPI Module of Arduino.

Pull the Transmission Enable pin pin 14 to ground to activate transmission. We should set the bits in same pattern on Encoder and Decoder IC to pair them. The primary function of HT12E is to encode a bit and send it out through the output pin. What is Web Browser. These pins are generally shorted by a resistor.
