source for CA3161 (or NTE2032)

[David Snowdon]

Hi Alex, these parts are not CMOS, so they don't require special 
handling. They were developed
in the mid '70s using I2L logic. Unfortunately these parts are no longer 
being made; the last manufacturer
shut down their CA3xxx line a couple of years ago.

Futurlec has a bad rep for delivering substandard parts (remember 
PolyPak ?). I remember buying some from Pacific
Semiconductor in 1999, but they now show none in stock.
