(1)
Full range (minimum or maximum) for LM2903 is –40°C to 125°C. All characteristics are measured with zero common-mode input
voltage, unless otherwise specified.
(2)
VCC MAX = 30 V for non-V devices and 32 V for V-suffix devices.
(3)
The voltage at either input should not be allowed to go negative by more than 0.3 V otherwise output may be incorrect and excessive
input current can flow. The upper end of the common-mode voltage range is limited by VCC – 2V. However only one input needs to be in
the valid common mode range, the other input can go up the maximum VCC level and the comparator provides a proper output state.
Either or both inputs can go to maximum VCC level without damage.
