port switches from one path to another. Charge injection is reduced because the injection from the DISCONNECT of the first path is compensated by the CONNECT of the
second path.
Switch inputs generate no significant power supply currents as they transition. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
