[1] tr = tf = 6 ns; when measuring fmax, there is no constraint to tr and tf with 50 % duty factor.
[2] VI values:
a) For 74HC4051: VI = VCC
b) For 74HCT4051: VI = 3 V
12. Additional dynamic characteristics

Recommended conditions and typical values; GND = 0 V; Tamb = 25 C; CL = 50 pF.
Vis is the input voltage at pins nYn or nZ, whichever is assigned as an input.
Vos is the output voltage at pins nYn or nZ, whichever is assigned as an output.
