Note 2: All devices are 100% production tested at T_A = +25NC. Limits over the operating temperature range are guaranteed by
design; not production tested.
Note 3: DR_ON(MAX) = ABS(R_ON(CH1) - R_ON(CH2)).
Note 4: Flatness is defined as the difference between the maximum and minimum value of on-resistance, as measured over speci-
fied analog-signal ranges.
Note 5: Between two switches.
