___________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 ratings
can cause permanent damage to the devices. Always
sequence V+ on first, then V-, then VL 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, and a Schottky
diode between V+ and VL for overvoltage protection
(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 oper-
ation is unchanged, and the difference between V+ and
V- should not exceed 11V.
Power-supply bypassing improves noise margin and
prevents switching noise from propagating from the V+
supply to other components. A 0.1F capacitor connect-
ed from V+ to GND is adequate for most applications.
