Note 3: 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.
Note 4: 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.
Note 5: 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. Limits are used to calculate National’s Average Outgoing Quality Level (AOQL).
Note 6: Typical numbers are at 25°C and represent the most likely parametric norm.
Note 7: Theta JA measured on a 3.0” x 3.5” four layer board, with two ounce copper on outer layers and one ounce copper on inner layers, two hundred and ten
12 mil thermal vias, and 2W power dissipation. Refer to evaluation board application note layout diagrams.
Note 8: Refer to BOM in Typical Application Bill of Materials — Table 1.
