(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 such that TJ = TA. No specification of parametric performance is indicated in the electrical tables under

conditions of internal self heating where TJ > TA.

(2)

All limits are specified by testing or statistical analysis.

(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. The typical values are not tested and are not guaranteed on

shipped production material.

(4)

Positive current corresponds to current flowing into the device.

(5)

Average Temperature Coefficient is determined by dividing the change in a parameter at temperature extremes by the total temperature

change.

Unless otherwise specified, all limits are ensured for TJ = 25°C. VCCI = VCCO = 5V, VEE = 0V, RL = 50Ω to VCCO-2V, VCM = 300
