Product speciï¬cation
74HC/HCT4067
CL = load capacitance including jig and
probe capacitance (see AC
CHARACTERISTICS for values).
RT = termination resistance should be equal
to the output impedance ZO of the
pulse generator.
tr
= tf = 6 ns, when measuring fmax, there is
no constraint on tr, tf with 50% duty
factor.
