Note 1:Signals on NO_, NC_, or COM_ exceeding V+ or V- are clamped by internal diodes. Limit forward-diode current to maxi-mum current rating.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functionaloperation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure toabsolute maximum rating conditions for extended periods may affect device reliability.ELECTRICAL CHARACTERISTICS—Dual Supplies

in this data sheet.

Note 3:Guaranteed by design.

Note 4:∆RON = RON_MAX- RON_MIN.

Note 5:Flatness is defined as the difference between the maximum and minimum values of on-resistance as measured over the

specified analog signal range.

Note 6:Leakage currents are 100% tested at the maximum-rated hot temperature and guaranteed by correlation at +25°C.Note 7:Off-isolation = 20log10[VCOM_ / (VNC_or VNO_)]. VCOM_= output, VNC_or VNO_= input to off switch.Note 8:Between any two switches.

Note 9:Leakage testing for single-supply operation is guaranteed by testing with dual supplies.
