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 see the NO_ Input Voltage section.
