Hi Mike,

Thanks very much for your response. I'm going bonkers here :-)

Yes, I'm sure it specified HC parts. I was kinda surprised myself because I
consider HC parts to be able to act so fast that they would pick up way too
much noise but yes,that's what it shows.

Forgive my ignorance,but what is an "unbuffered" CMOS gate? I was under the
impression that all CMOS inverters were just a single stage. I know it gets
more complex as you go to NAND,etc, and that they are usually implemented
(IIRC) as a NAND followed by two stages of inversion.

Also,what would the max freq. be on those parts you suggested. I need
something which can deliver at least about 10 times gain up to 50MHz. Since
I don't need (or even want) the output to be linear,I though it would be
cheapest and easiest to use a CMOS gate in linear mode,rather than an
expen$ive analog amplifier chip.

Thanks,

Sean
