Fault-Protected, High-Voltage
Single 8-to-1/Dual 4-to-1 Multiplexers
ELECTRICAL CHARACTERISTICS—Single +12V Supply (continued)
(V+ = +12V, V- = 0, VA_H = +2.4V, VA_L = +0.8V, VEN = +2.4V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at
TA = +25°C.) (Note 2)

Note 2: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 3: NO_ pins are fault protected and COM_ pins are not fault protected. The max input voltage on NO_ pins depends on the
COM_ load configuration. Generally the max input voltage is ±36V with ±15V supplies and a load referred to ground. For
more detailed information refer to NO_ Input Voltage section.
Note 4: Guaranteed by design.
Note 5: ∆RON = RON(MAX) - RON(MIN).
Note 6: Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed by correlation at TA = +25°C.
Note 7: Off-isolation = 20log10 (VCOM_ / VNO_ ), where VCOM_ = output and VNO_ = input to off switch.
Note 8: Between any two analog inputs.
Note 9: Leakage testing for single-supply operation is guaranteed by testing with dual supplies.
Note 10: Guaranteed by testing with dual supplies.
