What's a 125C0088?


Dick Ballard

Jan 1, 1970
I find many listings of commercial part suppliers for a 125C0088
(8-pin DIP), but not a data sheet in sight. It's part of an obsolete
light control actuated by a garage door opener remote. Other IC's in
the unit are a 125C86 (16-DIP) and a 125C0042 (8-DIP). All have the
National Semiconductor logo and are involved with decoding the input
from the RF remote. The unit was built circa 1992.

Any ideas what this critter is?
