Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS
devices. Do not exceed the absolute maximum ratings, because
stresses beyond the listed ratings may cause permanent damage
to the devices. Always sequence V+ on first, followed by V-, and
then the logic inputs. If power-supply sequencing is not possible,
add two small signal diodes or two current limiting resistors in
series with the supply pins for overvoltage protection (Figure 9).
Adding diodes reduces the analog signal range, but low switch
resistance and low leakage characteristics are unaffected.
