Supply voltage; 5V 2. In additional to itit also has 8 address lines which can generally be grounded along with the pin number 9.

These are the 8-bit address bits, which is used to protect your data. It is mainly used in interfacing RF and infrared circuits. Basically found in applications of remote control systems. This pin has to be connected to Ground 0V to enable the Transmission. Pull the Transmission Enable pin pin 14 to ground to activate transmission. Choosing Battery for Robots. Now first of all let me acquaint you about these two integrated circuits: These four pins are used to send data, the data encoded here will hr12e decoded on HT12D IC sharing the same address bits.

ht12e ht12d datasheet – ht12e ht12d datasheet

They can also be connected to switches to manually send and receive data. In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Simply put, HT12E converts the parallel inputs into serial output. Buy 15 or more pieces to get Free Shipping Option Availability: To find out more, including how to control cookies, see here: This site uses cookies.


If you want security you can connect any of the 8 pins to 5V to make it high. Connected to the Ground of circuit. 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 can make any changes on these 4-bits and they will be reflected on the output side of the HT12D decoder IC.

So if you are 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. SPI Module of Arduino.

You can know to set up the HT12D after this from here. The primary function of HT12E is to ht2d a bit and send it out through the output datssheet. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. 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. This pin outputs the parallel data serially. 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.


Interface GPS with Arduino. For decoding a annd the IC will requires an oscillator, luckily this IC has one in-built.

Can range from 2. These 12 bits are divided into 8 address bits and 4 data bits. This IC has a total of 18 pinsnine on either sides: TB Stepper Motor Driver 4.

Actual datsaheet may vary from the product photograph displayed above. These two ICs together form an Encoder and Decoder pair. Photograph just for reference.

HT12E Encoder IC

Transmission enable; active low. Choosing Motor For Robots. Customers who bought this product also purchased This cycle is repeated as long as TE is kept low.

Skip to content Gone are the days when we used to use wires to connect two devices to establish a communication path. I am now going to tell you about to control a certain robot wirelessly rather than using wires. Skip to main content. This IC hasmany applications in short range remote controlling. Submitted by admin on 30 October The Decoder receive the serial address and data from its corresponding decoder, transmitted by a carrier using an RF transmission medium and gives output to ans output pins after processing ht2e data.

Thanks a lot for helping us to maintain competitive prices. This high-density System-in-Package SiP integrates controller, power switches, and support components.
