I thought you were talking about putting them in series first. When I realized you didn't talk about a typical circuit setup, but to actually put them on top of each other then it made more sense.

Kind of a novice question but I wanted to check if I am right about something. I like the convenience of the UDN2981 source driver to provide switched power to for multiple loads. However, I would like to drive loads that requires about 1.5x higher amperage than the specified limit of the chip. Would it be OK to physically stack two of these chips on top of each other to double the current draw capacity that I am able to deliver? I have verified that it seems to work, but I am looking for some sage advice as to whether this is truly OK to do.
