Got some IC's marked:
HOA9026A /C 7800 303XA 27014
Found a vague reference as possible equivalent to LM143H
Anybody know anything about this IC?
I'd like to know what it is, or if it actually IS equivalent to the LM143H.

National Semiconductor. 8-Pin Can Package.
Precision markings, ....I'm wondering if maybe it's a military spec IC.

I deeply drill the WWW but no information about your mystery chip
Indeed it's should be some military/hi-rel device according to the package and the marking :eek:

There's a defense logistics website out there somewhere that I ran across once.
I'll see if I can find it again, and look there.
