| SYMBOL | DESCRIPTION |
|---|---|
| VCOM | Voltage at COM |
| VNC | Voltage at NC |
| VNO | Voltage at NO |
| ron | Resistance between COM and NC or COM and NO ports when the channel is ON |
| 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 |
| INC(OFF) | Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the OFF state |
| INO(OFF) | Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the OFF state |
| INC(ON) | Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the ON state and the output (COM) open |
| 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 or COM to NC) in the ON state and the output (NC or 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) |
| 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, NC, 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, NC, 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 (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, 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 |
| CNC(ON) | Capacitance at the NC port when the corresponding channel (NC to COM) is ON |
| CNO(ON) | Capacitance at the NO port when the corresponding channel (NO to COM) is ON |
| CCOM(ON) | Capacitance at the COM port when the corresponding channel (COM to NC or COM to NO) is ON |
| CI | Capacitance of control input (IN) |
| OISO | 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. |
| XTALK | 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. |
| BW | Bandwidth of the switch. This is the frequency where the gain of an ON channel is –3 dB below the DC gain. |
| THD | Total harmonic distortion describes the signal distortion caused by the analog switch. This is defined as the ratio of root mean square (RMS) value of the second, third, and higher harmonic to the absolute magnitude of fundamental harmonic. |
| I+ | Static power-supply current with the control (IN) pin at V+ or GND |
