HT12E Datasheet(PDF) – Holtek Semiconductor Inc

These are the 8-bit address bits, which is used to protect your data. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable.

TL — Programmable Reference Voltage. By continuing to use this website, you agree to their dayasheet. After one complete cycle of data transfer the pin TE goes in high impedance state, thus indicating 1 cycle of data transfer.

We should set the bits in same pattern on Encoder and Decoder IC to pair them. This pin outputs the parallel data serially. Supply voltage; 5V 2. It is very important that your Decoder should also have this same address for them to talk to each ht12d. The primary function of HT12E is to encode a bit and send it out through the output pin. Generally a resistor of value 51 KOhms can be used. HT12E IC has four bit parallel data inputwhich it then converts to serial data output.

The Encoded 12 bit output data can be obtained from this pin.

Virgin Galactic — Commercial Space Flight. 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.

HT12E Encoder IC Pin Diagram, Uses, Equivalents & Datasheet

For decoding a data the IC will requires an oscillator, luckily this IC has one in-built. Skip to main datasehet. This is an CMOS logic integrated circuit encoder. They can also be connected to switches to manually send and receive data. What is Web Browser. 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.


They are paired with 2 12 series of decoders for use in remote control system applications. So if you are working on a project which has to transmit a 4-bit data from one jt12e to other either by wire or wireless then this IC pair will be best ht21e for you.

Submitted by admin on 30 October This pin has to be connected to Ground 0V to enable the Transmission.

Simply put, HT12E converts the parallel inputs into serial output. The IC is has a wide range of operating voltage from 2. Thus this helps in setting up oscillations in the IC.

So out of the bits 8-bits will be datasheet to set address and the remaining 4-bit will datasyeet used to transmit data. Whenever an active low signal is ht12 at its TE pin then only the parallel data gets transferred serially at the output, otherwise the IC is in high impedance state. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to eatasheet. I am now going to tell you about to control a certain robot wirelessly rather than using wires.

Choosing Motor For Robots. In additional to itit also has 8 address lines which can generally be grounded along with the pin number 9. The IC has a built in oscillator. Interface SD Card with Arduino. Choosing Battery for Robots. These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits.


An LED can also be connected across this terminal to indicate output. To find out more, including how to control cookies, see here: Skip to content Gone are the days when we used to use wires to connect two devices to establish a communication path.

HT12E Encoder IC

This IC hasmany applications in short range remote controlling. 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 datasheeh output side of HT12D, ht21e we can make any changes on these 4-bits and they will be reflected on the output side of the HT12D decoder IC.

If you want security you can connect any of the 8 pins to 5V to make it high. 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. SPI Module of Arduino. Now first of all let me acquaint you about these two integrated circuits: Datashfet site uses cookies. Connected to the Ground of circuit. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.

Pull the Transmission Enable pin pin 14 to ground to activate transmission. Gone are the days when we used to use wires to connect two devices to establish a communication path. Can be used datxsheet Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc. Arduino based GPS receiver.
