DC NOISE MARGIN
The DC noise margin is defined as the input voltage range
from an ideal “1” or “0” input level which does not produce
output state change(s). The typical and guaranteed limit val-
ues of the input values VIL and VIH for the output(s) to be at a
fixed voltage VO are given in the Electrical Characteristics
table. VIL and VIH are presented graphically in Figure 11.
Guaranteed minimum noise margins for both the “1” and
“0” levels =
1.0 V with a 5.0 V supply
2.0 V with a 10.0 V supply
2.5 V with a 15.0 V supply
