HT12E Datasheet(PDF) – Holtek Semiconductor Inc

This cycle is repeated as long as TE is kept low. These 12 bits are divided into 8 address bits and 4 data bits. 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. HT12E IC has four bit parallel data inputwhich it then converts to serial data output. To find out more, including how od control cookies, see here: Connected to the Ground of circuit.

They can also be connected to switches to manually send and receive data. Pull the Transmission Enable pin pin 14 to ground to activate transmission.

It encodes the 12 bit parallel data into dataxheet for transmission through an RF transmitter. Can range from 2. Now first of all let me acquaint you about these two integrated circuits: The IC has a built in oscillator. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer. Submitted by admin on 30 October So out of the bits 8-bits will be used to set address and the remaining 4-bit will be used to transmit data.

HT12E Encoder IC

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

You can know to set up the HT12D after this from here. This IC hasmany applications in short range remote controlling.

I am now going to tell you about to control a certain robot wirelessly rather than using wires. This pin outputs the parallel data serially. As soon as TE returns to high, the encoder output completes its final cycle and then stops. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. This high-density System-in-Package SiP integrates controller, power switches, and support components. 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.

It is very important that your Decoder should also have this same address for them to talk to each other. They are paired with 2 12 series of decoders datasneet use in remote control system applications.

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 dattasheet make 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. This site uses cookies. Used for interfacing RF circuits generally MegaHz. HT12E has a transmission enable pin which is active low.

These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits. SPI Module of Arduino. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Choosing Motor For Robots. The Encoded 12 bit output data can be obtained from this pin. The IC is has a wide range of operating voltage from 2.

Interface SD Card with Arduino. This IC has a total of 18 pinsnine on either sides: Virgin Galactic — Commercial Space Flight. Interface GPS with Arduino. This is hh12e CMOS logic integrated circuit encoder. For decoding a data the IC will requires an oscillator, luckily this IC has one in-built.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

TL — Programmable Reference Voltage. The primary function of HT12E is to encode a bit and send it out through the output pin. Skip to content Gone are the days when we used to datashete wires to connect two devices to establish a communication path.

In additional to itit also has 8 address lines which can generally be grounded along with the pin number 9. Transmission enable; active low. Skip to main content.

Arduino based GPS receiver.
