(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.
