Does Linear Technology make a _fast_ open-drain output comparator?
All I'm finding are around 1us+ I'd like

Fast comparator and a diode.
LT319A? dual and judging from the packages available it is old
-Lasse
I thought of that, but I'm tight on headroom... need a VOL~0.2V ...Jim Thompson

I'll check it out, some of those oldies were quite good. ...Jim Thompson

Is this one fast enuogh?
Fast comparator and a gold-doped RF transistor?

Yep. Looks good!

Fast comparator and a 2N7002. Get rid of the base resistor.
You specified LTC, so I figured you were simulating. In sim, just use an ideal diode.
Sort of overkill for a 10mA load ;-) ...Jim Thompson

I was just shopping parts. Joerg pointed out a Microchip device that'll be perfect. ...Jim Thompson

Just happened to be looking for something else at Microchip and found the model
or go to here and browse around
Have not tried to plug it into any Spice engine
Monsoon kick in yet? Still a little early I suspect but I see Tucson got a pretty good drenching.

2.2 cents.
Thanks, Joe! We got heavy rain last night, and power out for about an hour... but I slept right thru it ;-)
The model... 200+ lines, tables, limits, all the crap that I chide about :-(
I'd guess I can write a model that matches that behavior... in about
1/10th the lines, and all bounds done with TANH ;-)After the job at hand I'll give that a try. ...Jim Thompson

And a big chunk of gate capacitance. ...Jim Thompson

VOL,MAX sucks.

I'm dealing only in low currents. ...Jim Thompson

Just tack this on your favorite comparator:
That would do it ;-) ...Jim Thompson
