(1) ΔR_on = R_on(max) – R_on(min)
(2) Typical values are at T_A = 25°C.
(3) Flatness is defined as the difference between the maximum and minimum value of r_on as measured over the specified analog signal
ranges.
(4) Leakage parameters are 100% tested at the maximum-rated hot operating temperature and specified by correlation at T_A = 25°C.
(5) OFF isolation = 20_log10 (V_COM/V_NO), V_COM = output, V_NO = input to OFF switch
