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 can cause permanent damage to the devices.
Always sequence V+ on first, then V-, followed by the
logic inputs, NO, or COM. If power-supply sequencing
is not possible, add two small signal diodes (D1, D2) in
series with 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 leak-
age characteristics. Device operation is unchanged,
and the difference between V+ and V- should not
exceed 44V. These protection diodes are not recom-
mended when using a single supply.
Off-Isolation at High Frequencies
In 50
systems, the high-frequency on-response of
these parts extends from DC to above 100MHz, with a
typical loss of -2dB. When the switch is turned off, how-
ever, it behaves like a capacitor, and off-isolation
decreases with increasing frequency. (Above 300MHz,
the switch actually passes more signal turned off than
turned on.) This effect is more pronounced with higher
source and load impedances.
