They don't impress me much. Yes, they can drive my 0.6pF active probes
problem, but connecting just one of their own inputs to an output slows
to half speed. The word "line driver" for their '125 seems somewhat
Propagation delay vs. load capacitance could be a problem with them.

Motorola's Mosaic3 process was really ugly, and with PECL you get all
the VCC noise
unattenuated to the output in the high state. But is is seldom that
bipolars wrt 1/f corners. I think I'll give the 100EP a try.
