ELECTRICAL CHARACTERISTICS—Single Supply (continued)

(V+ = +12V, V- = 0, VL = +5V, VIN_H = 2.4V, VIN_L = 0.8V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at

TA = +25°C.)

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: Guaranteed by design.

Note 4:

∆RON = RON(MAX) - RON(MIN).

Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the

specified analog signal range.

Note 6: Leakage parameters are 100% tested at maximum-rated hot temperature and guaranteed by correlation at +25°C.

Note 7: Off-isolation = 20 log10 [VCOM / (VNC or VNO)], VCOM = output, VNC or VNO = input to off switch.

Note 8: Between any two switches.

Note 9: Leakage testing at single supply is guaranteed by testing with dual supplies.
