(1)

Full range (minimum or maximum) for LM293A is –25°C to 85°C, and for LM393A is 0°C to 70°C. All characteristics are measured with

zero common-mode input voltage, unless otherwise specified.

(2)

The voltage at either input can not be allowed to go negative by more than 0.3V otherwise output can 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, and 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.
