Note 4: EN 55022:2006, +A1:2007, FCC Part 15 Subpart B: 2007. See Table 9 and layout for information on device under test.

Note 5: 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 6: The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin. Test method is per JESD22-AI14S.

Note 7: Min and Max limits are 100% production tested at an ambient temperature (T

through correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate National’s Average Outgoing Quality Level (AOQL).

Note 8: Typical numbers are at 25°C and represent the most likely parametric norm.
