_______________________________________________________________________________________
Note 3: All parameters are production tested at TA = +85°C, and guaranteed by design over the specified temperature range.
Note 4: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Note 5: All timing is measured using 20% and 80% levels.
Note 6: Off-Isolation = 20log10[VCOM_/(VNO_ or VNC_)], VCOM_ = output, VNO_ or VNC_ = input to off switch.
Note 7: Between any two switches.
