Note 1:
Absolute Maximum Ratings are those values beyond which dam-
age to the device may occur.
Note 2:
Unless otherwise specified all voltages are referenced to ground.

DC Electrical Characteristics
(Note 4)
Note 4:
For a power supply of 5V
±
10% the worst case output voltages (V
OH
, and V
OL
) occur for HC at 4.5V. Thus the 4.5V values should be used when
designing with this supply. Worst case V
IH
and V
IL
occur at V
CC
=
5.5V and 4.5V respectively. (The V
IH
value at 5.5V is 3.85V.) The worst case leakage cur-
rent (I
IN
, I
CC
, and I
OZ
) occur for CMOS at the higher voltage and so the 6.0V values should be used.
