I used the 2G17 at the input of an all cmos freq counter as a squarer feeding an LVC74 flipflop. At Vdd of 3.6V the combo was operational to almost 400MHz. it is when the '74 failed to divide reliably. The buffer itself was still putting out healthy levels. A more unconventional use is a RF amplifier and harmonic generator as the high current outputs have very steep edges, well under 1ns. With the outputs of both devices paralleled thru low value resistors followed by a simple LC matching network, the thing pushed over 20dBm at 100MHz
I use these LVC1G17 (and 1G14) all the time as customer facing io. Not back drivable, esd protection, decent driving current, fast, small, slow rise and mixed voltage tolerable, They are great as buffers to the 'outside'. Also available from NXP and Diodes too most of them.
Looks like you’re making good use of your fancy new SMD to DIP (edit: SIP) adapter boards! Guess I better order a set for myself, they look really handy.
With CMOS floating inputs causes shoot through currents that can burn out the transistors. With processors and FPGAs running from 0.8 V these days, these gates can be necessary for interfacing to the real world.
Could you put one of them on the curve tracer, to trace out the hysterical response curve? Not sure if there's an easy way to get power rails with the zero volt reference the curve tracing is using (AC coupling the signals, maybe?)...

Re-visiting the ol' 74 series Part 3. Seriously, I'm liking it. 👍
It's a pity that the max voltage isn't standardized to 5V.
Those modern processors run on super low voltages. If you're using one and need to interface with something these are the parts for you!

@@jspencerg ah right, it's single not dual! SIP. Good call.
Wow. I have no idea what you would want these for but obviously someone does.

Neat, because sometimes, you just don't want the signal inverted !
Please increase the frequency of your test 50-100MHz.
