Table 9-2 is a stress rating only, and functional oper-
ation at the maximums is not guaranteed. Functional
operating conditions are given in
9.4 D.C. Specifica-
tions
and
9.5 A.C. Specifications
.
Extended exposure to the Maximum Ratings may af-
fect device reliability. Furthermore, although the In-
tel386 DX contains protective circuitry to resist dam-
age from static electric discharge, always take pre-
cautions to avoid high static voltages or electric
fields.
