0.8Ω, Low-Voltage, Single-Supply Dual SPST
Analog Switches
ELECTRICAL CHARACTERISTICS—Single +1.8V Supply (continued)
(V+ = +1.8V, VIH = +1.0V, VIL = 0.4V, TA = TMIN to TMAX, unless otherwise specified. Typical values are at TA = +25°C.) (Notes 2, 3)

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value is a maximum, is
used in this data sheet.
Note 3: SOT23 packaged parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and
correlation. µMAX packaged parts -40°C specifications are guaranteed by design.
Note 4: ∆RON = RON(MAX) - RON(MIN).
Note 5: Flatness is defined as the difference between the maximum and the minimum value 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 two switches.
(TA = +25°C, unless otherwise noted.)
