Capacitance at the NC port when the corresponding channel (NC to COM) is OFF
Capacitance at the NO port when the corresponding channel (NO to COM) is OFF
Capacitance at the NC port when the corresponding channel (NC to COM) is ON
Capacitance at the NO port when the corresponding channel (NO to COM) is ON
Capacitance at the COM port when the corresponding channel (COM to NC or COM to NO) is ON

IN
OFF isolation of the switch is a measurement OFF-state switch impedance. This is measured in dB in a specific frequency,
with the corresponding channel (NC to COM or NO to COM) in the OFF state.
O
ISO
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.
X
TALK
BW
Bandwidth of the switch. This is the frequency in which the gain of an ON channel is −3 dB below the DC gain.
I
+
Static power-supply current with the control (IN) pin at V or GND
+
∆I
+
This is the increase in I for each control (IN) input that is at the specified voltage, rather than at V or GND.
