Note 2: All units are 100% production tested at T
A
= +25°C. Limits over the operating temperature range are guaranteed by design
and not production tested.
Note 3: The switch will turn off for voltages above (V
FP
); therefore, protecting downstream circuits in case of a fault condition.
Note 4: Fault-protection trip threshold limits are not production tested; guaranteed by design.

Note 6: Flatness is defined as the difference between the maximum and minimum value of on-resistance, as measured over
specified analog signal ranges.
Note 7: Between any two switches.
Note 8: Noise specification is measured peak to peak.
Note 9: Switch off-capacitance, switch on-capacitance, output skew between switches, and output skew same-switch limits are not
production tested; design guaranteed by correlation.
