... Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS— ...

... The switches’ open or closed states are controlled by TTL/CMOS-compatible input (IN_) pins. The MAX4555 and MAX4556 are characterized and guaranteed only with ±15V supplies, but they can oper- ate from a single supply up to +44V or non-symmetrical supplies with a voltage totaling less than +44V. The MAX4554 is fully characterized for operation from ± ...
