(1)

Full range (MIN or MAX) for LM293 is –55

°C to 125°C. All characteristics are measured with zero common-mode input voltage, unless

otherwise specified.

(2)

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 without damage.
