with Negative Signal Capability

Electrical Characteristics (continued)

(VCC = +2.7V to +5.0V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VCC = +3.0V, TA = +25°C.) (Note 3)

Note 3: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.

Note 4: The switch turns off for voltages above VFP, protecting downstream circuits in case of a fault condition.

Note 5: Guaranteed by design.

Note 6: ΔRON(MAX) = ABS(RON(CH1) - RON(CH2))

Note 7: Flatness is defined as the difference between the maximum and minimum value of on-resistance, as measured over speci-

fied analog signal ranges.

Note 8: Between two switches.
