The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in

this data sheet.

Guaranteed by design.

∆RON = ∆RON max - ∆RON min.

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

specified analog signal range.

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

Off Isolation = 20 log10 [ VCOM ⁄ (VNC or VNO) ], VCOM = output, VNC or VNO = input to off switch.

Between any two switches.
