Full range (MIN or MAX) for LM2903-Q1 is −40°C to 125°C and −40°C to 150°C for the LM2903E-Q1 . 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 for the inverting input (−), and the non-inverting input (+) can exceed the VCC level; the comparator provides a proper output state. Either or both inputs can go to 30 V (32V for V-suffix devices) without damage.
