(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 V
CC+
– 1.5 V for the inverting input ( – ), and the non-inverting input (+) can exceed the V
CC
level; the
comparator provides a proper output state. Either or both inputs can go to 30 V without damage.
