Electrical Characteristics (Limits in standard typeface are for TA = +25°C, bold typeface applies over -40°C to +85°C (Note 5), VCC

= 5V, VEE = 0V, VO = 1.4V, unless otherwise specified.)

Notes:

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

6. Over the full input common-mode range 0V to VCC-1.5V (at +25°C).

7. The input common-mode voltage of either input signal voltage should not be allowed to go negatively by more than 0.3V (at +25°C). The upper end of the

common-mode voltage range is VCC-1.5V (at +25°C), but either or both inputs can go to +36V without damages, independent of the magnitude of the VCC.
