Note 2: 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: ∆RON = RON(MAX) - RON(MIN).

Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the

specified analog signal range.

Note 6: Leakage parameters are 100% tested at maximum-rated hot temperature and guaranteed by correlation at +25°C.

Note 7: Off-isolation = 20log10 [VCOM / (VNC or VNO)], VCOM = output, VNC or VNO = input to off switch.

Note 8: Between any two switches.

Note 9: Leakage testing at single supply is guaranteed by testing with dual supplies.

(TA = +25°C, unless otherwise noted.)
