Turn-on time for the switch. This parameter is measured under the specified range of conditions and by the propagation
t
ON
delay between the digital control (IN) signal and analog outputs (COM/NC/NO) signal when the switch is turning ON.
Turn-off time for the switch. This parameter is measured under the specified range of conditions and by the propagation
t
OFF
delay between the digital control (IN) signal and analog outputs (COM/NC/NO) signal when the switch is turning OFF.
Break-before-make time. This parameter is measured under the specified range of conditions and by the propagation
t
BBM
delay between the output of two adjacent analog channels (NC and NO) when the control signal changes state.
Charge injection is a measurement of unwanted signal coupling from the control (IN) input to the analog (NC, NO, or
Q
C
COM) output. This is measured in coulombs ) and measured by the total charge induced due to switching of the control
input. Charge injection, Q
