... The MAX354/MAX355 also protect sensitive circuit components against voltages near or beyond the normal supplies. The MAX354 single 8-channel mux and the MAX355 dual 4-channel mux protect analog signals while oper- ating from a single 4.5V to 36V supply or ±4.5V to ±18V dual supplies. These muxes have 350Ω ...

... Figure 7. NO/COM Capacitance _______________Detailed Description Fault-Protection Circuitry Maxim’s MAX354/MAX355 are fully fault protected for continuous input voltages up to ±40V, whether or not the V+ and V- power supplies are present. These devices use a “series FET” protection scheme that not only protects the multiplexer output from overvoltage, but also limits the input current to sub-microamp levels ...
