DESCRIPTION
Voltage at COM
Voltage at NC
Voltage at NO
Resistance between COM and NC or COM and NO ports when the channel is on
Peak ON-state resistance over a specified voltage range
Difference of r_on between channels
Difference between the maximum and minimum value of r_on 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
worst-case input and output conditions
Leakage current measured at the NC port during the power-down condition, V₊ = 0
Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the off state under
worst-case input and output conditions
Leakage current measured at the NO port during the power-down condition, V₊ = 0
Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the on state and the
output (COM) being open
Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the on state and the
output (COM) being 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) being open
Leakage current measured at the COM port during the power-down condition, V₊ = 0
Minimum input voltage for logic high for the control input (IN)
Maximum input voltage for logic low for the control input (IN)
Voltage at (IN)
Leakage current measured at (IN)
Turnon 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 outputs (COM, NC, or NO) signal when the
switch is turning on.
Turnoff 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 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
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 the
control input. Charge injection, Q_C = C_L × ΔV_O, C_L is the load capacitance and ΔV_O is the change in analog output
voltage.
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 (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.
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.
