High-Speed, Low-Voltage, 4Ω,
SPDT CMOS Analog Switch
ELECTRICAL CHARACTERISTICS—Single +3V Supply (continued)
(V+ = +2.7V to +3.3V, VINH = 2.0V, VINL = 0.4V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)

Note 2: ΔRON = RON(MAX) - RON(MIN).
Note 3: RON flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog-signal range.
Note 4: Guaranteed by design.
Note 5: On-Leakage performed with voltage applied to COM, with NO and NC left unconnected.
Note 6: Off-Isolation = 20log10 (VO / VI), where VO is VCOM and VI is either VNC or VNO from the network analyzer.
Note 7: Crosstalk is measured between the two switches.
