ELECTRONICS ON-LINE

Finding components

and datasheets

Many readers phone and write us with questions about components. Typical

questions include: who’s the manufacturer of that IC, and where can I ﬁnd

a datasheet? Unfortunately we can not always help, mainly because of lack

of time (who else would look after the magazine?). However, you may not

have realized that with an Internet connection available you’ve access to

extensive databases covering components and datasheets.

Although this month’s subject was covered

before on the Electronics On-Line page (see

‘Semiconductor overviews’ in the March 1998

issue) as well as on a datasheet (issue Janu-

ary 1999), some more coverage is apparently

in order in view of the many requests we get

every day.

One of the best websites to start your

search for component data or datasheets is

still the Chip Directory [1] run by Jaap van

Ganswijk from the Netherlands. Since its ﬁrst

appearance on the web, the number of

approved mirror sites has risen to about 25, so

the site should have a good accessibility rate.

Although the Chip Directory by itself already

offers a substantial database of technical

speciﬁcations of all kinds of semiconductor, on

the homepage it also gives you an optional

access to other powerful search engines like

ChipDocs [2], ECG [3], Questlink [4], IC Mas-

ter [5] and Free Trade Zone [6]. Note that the

latter two are only accessible after registra-

tion. Most of these search engines start dig-

ging in the component archives run by semi-

conductor manufacturers, and then return

information on where the relevant component

(or its datasheet) may be found.

If you want to look a bit further and would

like to know manufacturer contact addresses,

a visit to the Hardware Web homepage [7] is

recommended. The site contains long lists of

electronics-related web addresses. There are

several overviews: web addresses only for

datasheets; addresses of semiconductor man-

ufacturers; distributors. There’s also a sepa-

rate overview of passive components and con-

nectors, plus a list of companies involved in

electronics test and measurement equipment.

Finally, there’s EG3 [8], a web

portal for electronics which not only

contains a component search

engine, but also information on lots

of other electronics and computer-

related subjects, including Internet

protocols and robotics, to mention

just two.
