ELECTRICAL CHARACTERISTICS—Single Supply
(V+ = 12V, V- = 0, VL = 5V, GND = 0, VINH = 2.4V, VINL = 0.8V, TA = TMIN to TMAX, unless otherwise noted.)
Note 2: Typical values are for design aid only, are not guaranteed, and are not subject to production testing. 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: Guaranteed by design.
Note 4: On-resistance match between channels and flatness are guaranteed only with bipolar-supply operation. Flatness is defined
as the difference between the maximum and the minimum value of on-resistance as measured at the extremes of the speci-
fied analog signal range.
Note 5: Leakage parameters IS(OFF), ID(OFF), ID(ON), and IS(ON) are 100% tested at the maximum rated hot temperature and guaranteed at +25°C.
Note 6: Off-Isolation Rejection Ratio = 20log (VD/VS), VD = output, VS = input to off switch.
Note 7: Between any two switches.
