FSA66 Low-Voltage UHS Single SPST Normally Open Analog Switch
FSA66 Rev. 1.0.1
AC Electrical Characteristics
All typical values are @ 25°C unless otherwise specified.
Capacitance
Notes:
7. All typical values are at the specified V
CC
and T
A
= 25°C.
8. This parameter is guaranteed by design, but is not tested. The switch contributes no propagation delay other than
the RC delay of the typical ON Resistance of the switch and the 50 pF load capacitance when driven by an ideal
voltage source (zero output impedance).
9. Guaranteed by design.
