High-Voltage, Fault-Protected

Analog Multiplexers

_______________________________________________________________________________________

Note 2: When the analog signal exceeds +13.5V or -12V, the blocking action of Maxim’s gate structure goes into operation. Only

leakage currents flow and the channel ON resistance rises to infinity.

Note 3: The value shown is the steady-state value. The transient leakage is typically 50µA. See

Detailed Description.

Note 4: Guaranteed by other static parameters.

Note 5: Digital input leakage is primarily due to the clamp diodes. Typical leakage is less than 1nA at +25°C.

Note 6: Leakage currents not tested at TA = cold temp.

Note 7: Electrical characteristics, such as ON Resistance, will change when power supplies other than ±15V are used.
