What is the fastest ic oneshot?

tunnel diode.

Good one but it is not an IC

Got Knock? - see: Viatrack Printed Circuit Designs (among other things)

void _-void-_ in the obvious place

Define 'fastest'. You might get a really narrow pulse one-shot by wiring some ECL thru a short delay line, and it's propagation delay ought to be low...

YWIA

Ok, I'll bite. It's got substrate, diffusions, junctions, contacts... It's integrated and it's a circuit...and it can be really, really fast. One might even argue that it has zero propagation delay. ;-) mike

SRD, in the ps range.

Ok, hard to set the pulse width to 1 ms, but he wanted the fastest.

Sorry for the confusion. I'm really looking for the fastest 74123 type of one shot. I want to use it to make short precision pulses at 10MHz. I'd like it to have complementary outputs. I'd like it to be CMOS. I'd like it to be temperature stable from 20F to 110F.

Regards

Numbers are often useful in the design process. Short? Precision? Stable? You can't be helped if you can't state what you need. Yes, this IS my favorite pet peeve... mike

What does "short precision pulses at 10MHz" mean and or why do you want a one shot to do that?

If all you want is short pulses at 10 MHz, consider the digital approach - Osc package and CPLD. 100 MHz should be simple. That's a 10 nSec pulse. Count to 10 and you have 10 MHz.

If you need to do something like turn a stream of wide pulses at

10 MHz into narrow pulses, the digital approach adds jitter. How much can you tolerate?
