Turn-on time for the switch. This parameter is measured under the specified range of conditions and by the propagation delay
t
ON
between the digital control (IN) signal and analog output (COM, NC, or NO) signal when the switch is turning ON.

t
OFF
between the digital control (IN) signal and analog output (COM, NC, or 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 delay
t
