Hmm, things aren't quite as I remembered them....
The datasheets from ON Semi should let you tell the difference between
the MC1495 and MC1494. But it seems ON Semi doesn't use the
MC159* numbers anymore, like Motorola did.
I'm fairly certain that the MC159* parts were specified over the military
temperature/voltage ranges, and their MC149* equivalents were their
commercial range counterparts. (Or vice-versa.) Now, it seems,
ON Semi uses just the MC149* part number, with a suffix to tell the
mil/commercial versions apart.
