Re: Fast monostable with a transistpor array

I wonder if one could design really fast stuff with the HFA3046.
Package parasitics look nasty. And the big package will force ugly PCB
routing. You can plop a single tiny transistor wherever you want.
 The HFA parts are either 5 NPNs or 5 PNPs, which is also awkward.

I did design a 1:1000 dual slope timer stretcher with them featuring
5 ps resolution. The nice thing was that temp effects cancelled.
We tested that with synthesized xtal ovens --> 1pps signal and a 1.0000000??0001 pps that slowly drifted by.
With a space proof ceramic flat pack with even worse parasitics.
And yes, Methinks it was Harris before, bought up by Renesas.
