Darrell,

The TI part number is probably still available from electronics
distributors, but most will probably not do business with an individual for
a single part. I can't tell you where to easily get the TI chip, but there
is a National Semiconductor part which should be a very good substitute. The
part number is LMC6482AIN. You should be able to purchase it from Digi-Key,
( www.digikey.com ) or 800-344-4539. They accept credit cards and will sell
small (or large) quantities to anyone.

The alpha suffixes on these part numbers are significant - The A indicates
tighter specifications on electrical parameters than a part without the A,
the I (eye) indicates industrial temperature range (-40C to +85C), and the N
(P on the TI part number) indicates the package type is a DIP (dual in-line
plastic). Don't accept any substitutes for these indicators.

Good luck!

p.s. - it's in the mid 70's here in Houston!   :>)
