Recommended Operating Conditions

Note 3: Limits over the full temperature are guaranteed by design, but not tested in production.

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 +18V without damages, independent of the magnitude of the VCC.

Limits in standard typeface are for TA=25

oC, bold typeface applies over T

A=-40

CC=5V, GND=0V,
