I have a TO18 transistor-like device removed from a 1970 intersil stopwatch board (featuring ICM7045). Looking at intersil data books I did not see anything with 7201. What could it be? Here's the pics - the logo seems to be intersil.

Probably an Intersil ICM7201?

page A-4 of the pdf mentions ICM7201 as obsolete.
