Notes:
9. Guaranteed by design.
10. Guaranteed by design but not production tested. The device contributes no other propagation delay other than the RC delay of the switch
ON resistance and the 50pF load capacitance, whne driven by an ideal voltage source with zero output impedance.
11. Off Isolation = 20 Log10 [ VA / VBn ] and is measured in dB.
12. TA = 25°C, f = 1MHz. Capacitance is characterized but not tested in production.
