ELECTRICAL CHARACTERISTICS—±2.5V Dual Supplies (continued)
(V+ = +2.5 ±10%, V- = -2.5V ±10%, VIH = +2.0V, VIL = +0.4V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at
V± = ±2.5V and TA = +25°C.)

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: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
Note 5: Guaranteed by design.
Note 6: Off-Isolation = 20log10 (VCOM_ / VNO_), VCOM_ = output, VNO_ = input to off switch.
Note 7: Between any two switches.
Note 8: ∆RON matching specifications for QFN packaged parts are guaranteed by design.
