4-Channel CMOS Analog Multiplexer
ELECTRICAL CHARACTERISTICS—Single +3V Supply (continued)
(V+ = +2.7V to +3.3V, VIH = 2.0V, VIL = 0.4V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at V+ = +3V,

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: TDFN parts are tested at +25°C and guaranteed by design and correlation over the entire temperature range.
Note 4: ΔRON = RON(MAX) - RON(MIN).
Note 5: RON and ΔRON matching specifications for TDFN-packaged parts are guaranteed by design.
Note 6: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
Note 7: Guaranteed by design.
Note 8: Off-isolation = 20log10 (VCOM / VNO), where VCOM = output and VNO = input to off switch.
Note 9: Between any two switches.
(TA = +25°C, unless otherwise noted.)
