ELECTRICAL CHARACTERISTICS—Single +3V Supply (continued)

(V+ = +2.7V to +3.6V, VIH = +2.0V, VIL = +0.8V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)

(Notes 2, 9)

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in

this data sheet.

Note 3:

∆RON = RON(MAX) - RON(MIN).

Note 4:

∆RON matching specifications for QFN-packaged parts are guaranteed by design.

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

specified analog signal ranges.

Note 6: Guaranteed by design.

Note 7: Off-Isolation = 20log10 (VCOM / VNO), VCOM = output, VNO = input to off switch.

Note 8: Between any two switches.

Note 9: QFN packaged parts are tested at +25°C and guaranteed by design and correlation over the entire temperature range.
