ELECTRICAL CHARACTERISTICS—Single +3.3V Supply

(V+ = 3.0V to 3.6V, GND = 0V, VINH = 2.4V, VINL = 0.6V, TA = TMIN to TMAX, unless otherwise noted.)

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:

Guaranteed by design.

Note 4:

∆RON = ∆RON max - ∆RON min.

Note 5:

Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the

specified analog signal range.

Note 6:

Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25°C.

Note 7:

Off Isolation = 20 log10 [ VCOM ⁄ (VNC or VNO) ], VCOM = output, VNC or VNO = input to off switch.

Note 8:

Between any two switches.
