__________Applications Information
Overvoltage Protection
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 the logic
inputs. If power-supply sequencing is not possible, 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 above GND, but low switch resistance and low leak-
age characteristics are unaffected. Device operation is
unchanged, and the difference between V+ and GND
should not exceed 17V.
