DC Electrical Characteristics

Note:
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 4.5V
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.
