(1) The algebraic convention, whereby the most negative value is a minimum and the most positive value is a maximum.
(2) Parts are tested at 85°C and specified by design and correlation over the full temperature range.
(3) Typical values are at T_A = 25°C.
(4) ∆r_on = r_on(max) – r_on(min)
(5) Flatness is defined as the difference between the maximum and minimum value of r_on as measured over the specified analog signal
ranges.
(6) Leakage parameters are 100% tested at the maximum-rated hot operating temperature and specified by correlation at T_A = 25°C.
(7) OFF isolation = 20_log10 (V_COM/V_NO), V_COM = output, V_NO = input to OFF switch
