If you
are an Electronic Engineer or an Enthusiast, you must know about datasheet.
Datasheet is a piece of paper that contains information about a specific component. It
tells the designer or analyzer requirements, limitation and specification of
component in form of graphs, curves and tables.
Here
we are not going into details of it, but just to give you an idea that how to read
and what information you look for in a datasheet.
For a
beginner here are three simple things to notice in a datasheet.
1. Pin Configuration
labels
the pins on the package & Functions tell about the specific function
of each pin of component.
2.
Absolute
Ratings are
maximum values (like voltage, current, temperature etc.) that a component can endure. They should not be exceeded otherwise components will burn.
3.
Recommended Ratings
are recommended
by manufacturers, they are little less than absolute ratings. These are
recommended because if someone uses the absolute maximum values then even a small
change in relevant quantity (like temperature change, voltage fluctuations) can
lead to the destruction of whole circuit. However, you can use Absolute Ratings
also.
Let us take an example of NE555 Timer IC's Datasheet.
First,
take a look at pin configuration. It shows a picture of IC and labels its pins. A table explains each pin's functions.
Absolute
Ratings Section tells that how much maximum voltage we can apply to its
different pins, maximum output current. Up to what maximum or minimum temperature IC can function
without any fault.
Recommended
ratings, as previously stated, tell us little less value from the absolute
ratings for IC.
I think
for a beginner these are enough things to remember and practice. In some future
post, we shall explain about curves and graphs, until then keep learning and
help others to learn.

knows everything.
