ron
Resistance between COM and NC or COM and NO ports when the channel is ON
Difference of ron between channels in a specific device
∆ron
ron(flat)
INC(OFF)
INO(OFF)
Difference between the maximum and minimum value of ron in a channel over the specified range of conditions
Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the OFF state
Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the OFF state
Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the ON state and the output
(COM) open
INC(ON)
INO(ON)
Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the ON state and the output
(COM) open
Leakage current measured at the COM port, with the corresponding channel (COM to NO or COM to NC) in the ON state
and the output (NC or NO) open
ICOM(ON)
VIH
VIL
Minimum input voltage for logic high for the control input (IN)
Maximum input voltage for logic low for the control input (IN)
Voltage at the control input (IN)
VI
IIH, IIL
Leakage current measured at the control input (IN)
Turn-on time for the switch. This parameter is measured under the specified range of conditions and by the propagation
delay between the digital control (IN) signal and analog output (COM or NO) signal when the switch is turning ON.
tON
tOFF
tBBM
Turn-off time for the switch. This parameter is measured under the specified range of conditions and by the propagation
delay between the digital control (IN) signal and analog output (COM 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 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 (NO or COM)
output. This is measured in coulomb (C) and measured by the total charge induced due to switching of the control
input.Charge injection, QC = CL×∆ VCOM, CL is the load capacitance and ∆VCOM is the change in analog output voltage.

CI
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
Capacitance of control input (IN)
OFF isolation of the switch is a measurement of 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.
OISO
BW
THD
I+
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 is defined as the ratio of the root mean square (RMS) value of the second, third, and higher
harmonics to the magnitude of fundamental harmonic.
