ITT / 492-5 / 7445 - these appear to be LED drivers.
I've never seen a part
How about a 75492? I think that's an LED driver? The 7445 part sounds
like a date code...
number like this. BTW, the "7445" is
printed vertically, the rest of the
p/n is printed horizontally (as normal).
NSA298 / NS 436 - the "NS" looks a LOT like one of National
Semiconductor's
old logos. Did NatSemi ever make LED display panels?
Very much so! IIRC the display in the Science of Cambridge MK14 was an
NatSemi part (and was originally a calculator display). I've certainly
seen a NatSemi LED (and display) databook, I may have one somewhere.
