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

HT12E Encoder IC

The 4-bit data that has to be sent has to be given to the pins AD0 datssheet AD1 and an address of 8-bit has to be set using the pins A0 to A7.

This is an CMOS logic integrated circuit encoder. Return and Refund Policy.

HT12E IC has four bit parallel data inputwhich it then converts to serial data output. Thus this helps in setting up oscillations in the IC. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. Can range from 2. We will lauch an immediate investigation and try our best to beat the price, if it proves to be the same product.

The IC has a built in oscillator. An LED can also be connected across this terminal to indicate output. The encoded bit can be obtained from the Dout pin pin We will notify you the result by email. It is mainly used in interfacing RF and infrared circuits. Choosing Motor For Robots. Submitted by admin on 30 October The IC is has a wide range of operating voltage from 2. Supply voltage; 5V 2. Skip to content Ht21d are the days when we used to use wires to connect two devices to htt12e a communication path.


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.

Buy 15 or more pieces to get Free Shipping Option Availability: In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground.

HT12D/HT12F – Product Details – Holtek

These 12 bits are divided into 8 address bits and 4 data bits. Pull the Transmission Enable pin pin 14 to ground to activate transmission. These are the 8-bit address bits, which is used to protect your data. Gone are the days when we used to use wires to connect two devices to establish a communication path.

Generally a resistor of value 51 KOhms can be used. Connected to the Ground of circuit. This oscillator can be used by connecting these two pins through a 1M Resistor. Simply put, HT12E converts the parallel inputs into serial output. HT12E has a transmission enable pin which is active low. SPI Module of Arduino.


This ICs are paired with each other. Now first of all let me acquaint satasheet about these two integrated circuits: These two ICs together form an Encoder and Decoder pair. This site uses cookies. Be the first to write a review. TB H1t2d Motor Driver 4. This IC hasmany applications in short range remote controlling. 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.

Photograph just for reference. You can know to set up the HT12D after this from here.

It is very important that your Decoder should also have this same address for them to talk to each other. Customers who bought this product also purchased It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. Choosing Battery for Robots.

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 the output pins after processing the data. The primary function of HT12E is to encode a bit and send it out through the output pin. By continuing to use this website, you agree to their use.
