According to the IC Master:

I do not show a 8018BH, but do show a ICL8018AC by Intersil.  This
part is a Quad Current Switch, a high precision switch for use
in current summing D/A converters.  This doesn't seem like an
incredibly probable match, but I don't have any listing for a
CO10444D-01 or CO2837.

Good luck,
David
