Turn-on time for the switch. This parameter is measured under the specified range of conditions and by the
t
ON
propagation delay between the digital control (IN) signal and analog outputs (COM, NC, or 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
t
OFF
propagation delay between the digital control (IN) signal and analog outputs (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
t
BBM
propagation 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 COM) output. This is measured in coulomb (C) and measured by the total charge induced due to switching of

OFF isolation of the switch is a measurement OFF-state switch impedance. This is measured in dB in a specific
OISO
frequency, with the corresponding channel (NC to COM or NO to COM) in the OFF state.
Crosstalk is a measurement of unwanted signal coupling from an ON channel to an OFF channel (NC to NO or NO

to NC). This is measured in a specific frequency and in dB.
BW Bandwidth of the switch. This is the frequency in which the gain of an ON channel is –3 dB below the DC gain.
Total harmonic distortion describes the signal distortion caused by the analog switch. This is defined as the ratio or
THD root mean square (RMS) value of the second, third, and higher harmonic to the absolute magnitude of the
fundamental harmonic.
