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: ∆RON = RON(MAX) - RON(MIN).
Note 4: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Note 5: Guaranteed by design.
Note 6: Off-Isolation = 20log10 (VCOM/VNO), VCOM = output, VNO = input to off switch.
Note 7: Between any two switches.
Note 8: ∆RON matching specifications for QFN packaged parts are guaranteed by design.
Note 9: Parts are tested at the maximum hot-rated temperature. Limits across the entire temperature range are guaranteed by
design and correlation.
