Input pulse definition:
tr = tf = 6 ns, when measuring fmax, there is no constraint on tr, tf with 50% duty factor.
74HC2G66: VM = 50%; VI = GND to VCC.
74HCT2G66: VM = 1.3 V; VI = GND to 3.0 V.

Definitions for test circuit:
RL = Load resistor.
CL = Load capacitance including jig and probe capacitance.
RT = Termination resistance should be equal to the output impedance Zo of the pulse generator.
