PARAMETER DESCRIPTION
SYMBOL
DESCRIPTION
VCOM
Voltage at COM
VNO
Voltage at NO
ron
Resistance between COM and NO ports when the channel is ON
rpeak
Peak on-state resistance over a specified voltage range
ron
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
INO(OFF)
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
INO(PWROFF)
Leakage current measured at the NO port during the power-down condition, V+ = 0
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
ICOM(ON)
Leakage current measured at the COM port, with the corresponding channel (COM to NO) in the ON state and the output
(NO) open
ICOM(OFF)
Leakage current measured at the COM port, with the corresponding channel (COM to NC) in the OFF state under
worst-case input and output conditions
ICOM(PWROFF)
Leakage current measured at the COM port during the power-down condition, V+ = 0
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)
tON
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.
tOFF
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.
tBBM
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.
QC
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.
