AC Electrical Characteristics
Capacitance12
Notes:
9. Guaranteed by Design.
10. This parameter is guaranteed by design but not tested. The bus switch contributes no propagation delay other than the
RC delay of the On Resistance of the switch and the 50 pF load capacitance, when driven by an ideal voltage source
(zero output impedance).
11. Off Isolation = 20 log10 [VA / VBn]
12. TA = +25°C, f = 1 MHz, Capacitance is characterized but not tested in production.
