Good guess, but the power pins don't seem to line up. My best guess
is an A-D converter (there's a temperature probe on this oven).
Funny, the number shows up on parts reseller sites in searches, but
no descriptions. I wonder if the entries are contrived.
Is there a date code? (I'm guessing mid-late-70s). Haven't found any
mention in the 1981 IC Master, which is generally pretty good for
these sort of things.
