AC Electrical Characteristics
Note 9: This parameter is guaranteed by design but is not tested. The bus switch contributes no propagation delay other than the RC delay of the typical On
Resistance of the switch and the 50pF load capacitance, when driven by an ideal voltage source (zero output impedance).
Capacitance (Note 10)
Note 10: TA
25qC, f 1 MHz, Capacitance is characterized but not tested.
AC Loading and Waveforms
Note: Input driven by 50
: source terminated in 50:
Note: CL includes load and stray capacitance
Note: Input PRR
1.0 MHz, tW 500 ns
