Low RDSon Logic CMOS Gate

Klaus Kragelund · 2012-10-01T17:33:00+00:00

Hi I need a CMOS gate with low voltage drop at about 30mA current source and s ink. The tiny logic NL27WZ14 has 600mV drop at 32mA which equates to 18ohm RDS on. I am searching for a device with less than 5-10 ohms and it would need to b e ok to parallel to get lower resistance. Also, it must not have to much cr ossover shoot-through (so probably schmitt trigger type) and must have low dissipation at high operational frequency (1-10MHz) Any one have a part in mind? Thanks Klaus

Internal nodes? Where on the data sheet?

You never deliver actual facts or numbers. You actually don't know.

And where's that great triac circuit?

I'm just mocking your tirade when I missed a bit of information on a data sheet... What? Can't take a dose of your own crap ?:-)

Of course I know, exactly Those ON-Semi redesigns are still loaded on the PSpice machine.

But you can calculate that from the data sheet. The only thing missing... from the data sheet, like you'd know, is the "stack" ratio... the ratio of driven to driving size... it's typically ~3X.

To be exact, refer to...

Shrink parameter = 0.8

So now bless us with your superb IQ and YOU show us the numbers. You can't, you weenie.

Sitting quietly... annoying you. ...Jim Thompson

You'd be more effective if you were right. You weren't and you aren't.

As usual, no answers from the "Master Circuit Designer"

Senile old fool. You won't post it because it doesn't exist or you're afraid to show its bugs.

Nope. I'm just proving that you're a know-nothing weenie. I expect some junior engineer to jump forth momentarily and show you up ;-) ...Jim Thompson
