Does anyone know if there is a difference
between the ULN2003 and the ULN2003A? I realize that
in cases like this, the *A version is usually backwards
compatible with the regular kind, but I'm having some
problems with a ULN2003A in a circuit that calls for
a plain, old ULN2003, and I'm wondering if there is some
difference in the two chips that could account for this.

Thanks very much for any info.

Sprague semi is now Allegro semiconductor.
