Yes, they make a CMOS version of this. You can get it
from Maxim (MAX490), Linear Technology (LTC490) or
Sipex (SP490). I bought a bunch from LTC a few years ago,
and they exhibited a fatal CMOS latchup error, which
cost my company most of a million dollars by the time we
recalled thousands of products to replace the LTC490s. LTC
wouldn't even take back the defective parts, claiming that
they met the strict letter of the spec.

Maxim, on the other hand, makes a wonderful part that we've
been using for a long time, and they don't latch up like the
LTC parts do. LTC later offered an improved version of the
LTC490, which only latched up somewhat less often. Bzzzzzttt...
thank you for playing.

Sipex, bless their hearts, made a part that exhibited even
worse latchup than LTC! Fortunately I was highly paranoid by
this point, and tested all proposed vendors for immunity to
static discharge in operating conditions. Maxim and the original
TI 75176 were the only two which didn't die in interesting and
horrible ways.

I'd buy the Maxim part....in case you hadn't guessed by now.
