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鈥?9
