Δron
Difference of ron between channels in a specific device
ron(flat)
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 under
INC(OFF)
worst-case input and output conditions
INC(PWROFF)
Leakage current measured at the NC port during the power-off condition, V+ = 0
INO(OFF)
Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the OFF state
INO(PWROFF)

Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the ON state and the output
INC(ON)
(COM) open
Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the ON state and the output
INO(ON)
(COM) open
Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the OFF state and the output
INO(OFF)
(COM) open
Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the ON state and the output
INO(ON)
(COM) open
ICOM(OFF)
Leakage current measured at the COM port, with the corresponding channel (COM to NO) in the OFF state
ICOM(PWROFF)
Leakage current measured at the COM port during the power-off condition, V+ = 0
Leakage current measured at the COM port, with the corresponding channel (COM to NO) in the ON state and the output
ICOM(ON)
(NO) open
VIH
Minimum input voltage for logic high for the control input (IN)
VIL
Maximum input voltage for logic low for the control input (IN)
VI
Voltage at the control input (IN)
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
tON
delay between the digital control (IN) signal and analog output (COM 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 propagation
tOFF
delay between the digital control (IN) signal and analog output (COM or NO) signal when the switch is turning OFF.
Make-before-break time. This parameter is measured under the specified range of conditions and by the propagation delay
tMBB
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)
QC
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 × ΔVCOM, CL is the load capacitance and ΔVCOM is the change in analog output voltage.
CNC(OFF)
Capacitance at the NC port when the corresponding channel (NC to COM) is OFF
CNO(OFF)
Capacitance at the NO port when the corresponding channel (NO to COM) is OFF
