Specifications are 100% tested at TA = +85°C only, and guaranteed by design and characterization over the specified
temperature range.
Guaranteed by design and characterization; not production tested.
∆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 ranges.
Off-isolation = 20log10 (VCOM_ / VNO_), VCOM_ = output, VNO_ = input to off switch.
