NOTES
(1)
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is
intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
(2)
The human body model is a 100pF capacitor discharged through a 1.5 kΩ resistor into each pin. Test method is per JESD-22-114.
(3)
Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality
Control (SQC) methods.
(4)
Typical numbers are at 25°C and represent the most likely parametric norm.
(5)
Theta JA measured on a 3.5” x 3.5” four layer board, with three ounce copper on outer layers and two ounce copper on inner layers, sixty 10 mil thermal vias, no air
flow, and 1W power dissipation. Refer to application note layout diagrams.
