Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings, because stresses beyond the listed rat-
ings may cause permanent damage to the devices.
Always sequence V+ on first, followed by V-, and then
logic inputs. If power-supply sequencing is not possi-
ble, add two small signal diodes in series with supply
pins for overvoltage protection (Figure 1). Adding
diodes reduces the analog signal range to 1V below V+
and 1V below V-, but low switch resistance and low
leakage characteristics are unaffected. Device opera-
tion is unchanged, and the difference between V+ and
V- should not exceed 17V.
