Replacement for obsolete IC????

[watchmaker]

I need to replace a 74HC132P.  Is it appropriate to try a 74HC132N?  Both are DIP.

Thanks!

I've always thought that the P or N suffix was the package type. So if they are both DIP, it won't make a difference.

Apparently, the "P" denotes the TSSOP package, which has quite different dimensions than the PDIP package for the "N" suffix.

If you can't get the correct package or the package has become obsolete, get these DIP Adapter Converter Plate or similar from your favourite distributor.
Some of the kits have the Dupont pins as well. The kits are just so handy to have around.

The package suffixes are not entirely standardized between manufacturers.
What was commonly done for TTL logic chips was to package them in both plastic (epoxy) as well as hermetic ceramic and glass. The latter is impervious to moisture and reactive gasses and more thermally conductive, which was required in some industrial or aerospace applications. The plastic ("PDIP": Plastic Dual In-line Package) versions are much cheaper, of course.
For some higher pin-count chips, there were also "Shrink DIP" and "Staggered/Dual row DIP" but those aren't relevant to a 14-pin logic.

When reading the thread title, I thought you meant you were searching for an in-production substitute for an obsolete chip. 74HC logic may be compatible with AC, ACT, or even ALS.

WOW.  Thank you all.  Good to know not all DIPs are the same (there is a joke  in there somewhere).

JWillis,  I will try out those adapters.

Being inexperienced, I want to stay within the same chip family right now.

You can still buy the DIP version from Digikey and other suppliers:
Toshiba version
Ti version (Broader temperature range spec than the one above)

As posted by helius, the suffix is not standard across manufacturers. So just search for "74HC132" at your favorite supplier and ensure it's in a DIP package.
