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.
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
Found it.
If anybody's interested: http://www.dscc.dla.mil
microcircuit cross reference.
Dies owned by Rochester Electronics in Massacusetts, Vendor Part # 7800 303XA
Actual Device LM143H, High Voltage Op-Amp.
