Note 2: ∆RON = RON(MAX) - RON(MIN).
Note 3: RON Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Note 4: Guaranteed by design.
Note 5: On-Leakage performed with voltage applied to COM_, with NO_ and NC_ left floating.
Note 6: Off-Isolation = 20log10 (VO_ / VI_), where VO is VCOM_ and VI is VNC_ or VNO_ from the network analyzer.
Note 7: Crosstalk is measured between the two switches.
Note 8: RON and ∆RON matching specifications for QFN-packaged parts are guaranteed by design.
