C. All characteristics are measured with zero common-mode input voltage, unless otherwise
specified.
VCC MAX = 30 V for non-V devices and 32 V for V-suffix devices.
§The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage
range is VCC+ 1.5 V, but either or both inputs can go to 30 V (32 V for V-suffix devices) without damage.
