NOTE:

(1) Electrical table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very

limited self-heating of the device.

(2) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlations using statistical

quality control (SQC) method.

(3) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary

over time and will also depend on the application and configuration.

(4) This parameter is ensured by design and/or characterization and is not tested in production.

(5) Positive current corresponds to current flowing into the device.

(6) The voltage at either the input or common mode should not be allowed to negative by more that 0.3 V. The upper end of the common-

mode voltage range is (V+) – 1.5 V; however, one input can exceed Vs, and the comparator will provide a proper output state as long

as the other input remains in the common-mode range. Either or both inputs can go to 36 V without damage.

(7) High-to-low and low-to-high refers to the transition at the input.
