Note 4:
For a power supply of 5V
g
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
e
5.5V and 4.5V respectively. (The V
IH
value at 5.5V is 3.85V.) The worst-case leakage current (I
IN
,
I
CC
, and I
OZ
) occur for CMOS at the higher voltage and so the 6.0V values should be used.
**
V
IL
limits are currently tested at 20% of V
CC
. The above V
IL
specification (30% of V
CC
) will be implemented no later than Q1, CY’89.
