Applications Information
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 can
cause permanent damage to the devices. Always
sequence V+ on first, then V-, followed by the logic
inputs, NO, NC, or COM. If proper power-supply
sequencing is not possible, add two small-signal diodes
(D1, D2) in series with the supply pins (Figure 1). Adding
diodes reduces the analog signal range to one diode
drop below V+ and one diode drop above V- but does
not affect the devices
’
low switch resistance and low
leakage characteristics. Device operation is unchanged,
and the difference between V+ and V- should not
exceed 12V.
Power-supply bypassing improves noise margin and
prevents switching noise from propagating from the V+
supply to other components. A 0.1μF capacitor connect-
ed from V+ to GND is adequate for most applications.
