Hello All...I have a couple of tubes of IC's with NO ideas as to what they
are. Any help
would be appreciated. They're 8 Pin Dip packages manufactured by Texas
Instruments
and have the numbers...

SP61CAP3P
4CA8LKT

I've done Google searches, searched the Texas Web Site, ChipDirectory.com
all with no luck.

Hopefully SOMEONE has an idea to what they are.

MANY thanks in advance.....Dean.
