Limits in standard typeface are for TA=25

oC, bold typeface applies over -40oC to 85oC (Note 2), V

CC=5V, VEE=0V, VO=1.4V

unless otherwise specified.

Note 2: Limits over the full temperature are guaranteed by design, but not tested in production.

Note 3: Over the full input common-mode range 0V to VCC-1.5V(at 25

oC).

Note 4: The input common-mode voltage of either input signal voltage should not be allowed to go negatively by

more than 0.3V (at 25oC). The upper end of the common-mode voltage range is VCC-1.5V (at 25

oC), but either or

both inputs can go to +36V without damages, independent of the magnitude of the VCC.
