Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
3. For a power supply of 5 V ±10% the worst−case output voltages (V
OH
, and V
OL
) occur for HC at 4.5 V. Thus the 4.5 V values should be used
when designing with this supply. Worst−case V
IH
and V
IL
occur at V
CC
= 5.5 V and 4.5 V respectively. (The V
IH
value at 5.5 V is 3.85 V.)
The worst−case leakage current (I
IN
, I
CC
, and I
OZ
) occur for CMOS at the higher voltage and so the 6.0 V values should be used.
