80ns is nowhere near fast enough!. That's about 12MHz, the analyser is a

The LM319/80nS was mentioned as a starting point, fast enough to be useful for a lot of
work, slower ones are way slower, the latest linear ref. manual that I have (National
Semi./1988) has comparators down to 20nS (with complementary outputs).
(Actually, I have a few NOS Motorola 10124 TTL->ECL translators if they are that hard
to come by and someone is desperate.)
