5.0V Electrical Characteristics
5.0V, V
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: Human Body Model, applicable std. MIL-STD-883, Method 3015.7. Machine model, applicable std JESD22–A115–A (ESSD MM srd of JEDEC). Field
induced Charge-Device Model, applicable std. JESD22–C101–C. (ESD FICDM std of JEDEC).
Note 3: The maximum power dissipation is a function of T
P
Note 4: 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 T
T
Note 5: Boldface limits apply to temperature range of −40°C to 125°C
Note 6: All limits are guaranteed by testing or statistical analysis.
Note 7: 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.
