I've been searching the net for a comprehensive list of drawings of IC
packages, specifically, all things "SO" (ie, SO, SOP, TSOP, SSOP, TVSOP,
etc.). What does come up are lists of packages, but no drawings.

I need to have dimensions listed as well, similar to what is typically
provided in datasheets.

Thanks.

Thats your answer, grab the data sheets. ;-)

That's what I resort to, although it really would be nice if there was a
one stop shop of package drawings or dimensions. There are so many
different packages now that I can't keep track of them all.


For example this datasheet has 5 different package drawings that it calls
"Small Outline Package", all with different dimensions:

http://focus.ti.com/lit/ds/symlink/sn74hct244.pdf

Isn't the idea of a package "name" supposed be a single identity including
dimensions (differing, of course, in length, to accommodate different pin
counts)?

From the same manufacturer, no less...

Thanks,
Dave

According to this source, the same package (listed in the TI datasheet as
"SOP") might a large SOIC-20:

Am I the only one confused?

Probably.

SOP = Small Outline Package

SOIC = Small Outline IC

That's another problem, there are special package types that are called
different things depending on the manufacture.

I've recently worked on some designs around TI chips in their "PowerPAD"
packages which are SOIC and SSOP equivalent but with an exposed metal
pad under the die, and of course different names. I've gone to just
ignoring all the packages included in the PCB software and drawing my
own from the datasheet of each part I use, it's less hassle in the long run.

I agree, I do that too. I collect them slowly and reuse them. Considering SMT
is full of 'standards' it's amazing how there are so many, and some so loose,
that there might as well not be any.

When I saw Baron's post I saw pretty much the same thing I was going to say
when I first saw the original post. I hadn't replied, because I'd hoped that
the standards were adequately adhered to, and that someone who knows far more
than I do might point out a definitive source, but most replies here seem to
suggest that only going to the source of the part to be used is going to get
viable data for it. Maybe not even then.

Sometimes I get the bright light, the maginfier, the digital vernier scale,
and measure the damn things myself! That way I KNOW it fits.

http://www.latticesemi.com/lit/docs/package/pkg.pdf

Thanks for that.

Just my luck: Lattice have updated that document by deleting all SOIC
packages, the ones I apparently need...

A good reference otherwise, tho.

Thanks again.

Board houses usually adhere to the IPC standards, unless its oddball
stuff.

You need the JEDEC standards. Bless their hearts, the standards are free
upon registration.

For example, the "Plastic Shrink Small Outline Package (SSOP) Family.
R-PDSO/SSOP/SOIC" is covered by MO-137E, Mar 2010 over at
http://www.jedec.org/standards-documents/docs/mo-137e

Get thee hence to http://www.jedec.org/

Some semiconductor manufacturers also provide package drawings. IIRC
NXP is one of them.

Diodes Inc also has a fair set.

I have always had good luck finding specs at Digikey, never tried
mouser .

Don't know if its on wwwland but the paper versions of UK RS components
catalogue have an extensive pictorial listing of types with equivalents,
then look up dimensions once the package designation is known.

Yes it can get very confusing. The "Jedec" designations are given at
the bottom of each drawing. AFAIA that designation should identify a
package uniquely.

That's the wonderful thing about standards, there're so many to choose from.
JEDEC stretches that even further everyone gets their own "standards".
