Note:
3. For a power supply of 5V ±10%, the worst-case output voltages (V
OH
, and V
OL
) occur for HC at 4.5V. 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; V
IH
value at 5.5V is 3.85V. The worst-case leakage current (I
IN
, I
CC
, and I
OZ
) occurs for CMOS at
the higher voltage; so the 6.0V values should be used.
