Note 2: Typical values are for design aid only, are not guaranteed and are not subject to production testing. The algebraic convention,

where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet.

Note 3: Guaranteed by design.

Note 4: On-resistance match between channels and flatness are guaranteed only with bipolar-supply operation. Flatness is defined

as the difference between the maximum and the minimum value of on-resistance as measured at the extremes of the speci-

fied analog signal range.

Note 5: Leakage parameters IS(OFF), ID(OFF), ID(ON), and IS(ON), are100% tested at the maximum rated hot temperature and guaranteed at +25°C.

Note 6: Off-Isolation Rejection Ratio = 20log (VD/VS), VD = output, VS = input to off switch.

Note 7: Between any two switches.
