Electrical Characteristics Specifications with standard typeface are for T
J = 25°C only; limits in bold face type
apply over the operating junction temperature range T
J of -55°C to 125°C. Minimum and maximum limits are guaranteed through
test, design, or statistical correlation. Typical values represent the most likely parametric norm at T
J = 25°C, and are provided for
reference purposes only. V
IN = VEN = 3.3V, unless otherwise indicated in the conditions column.

Note 3:
θ
JA measured on a 2.25” x 2.25” (5.8 cm x 5.8 cm) four layer board, with one ounce copper, thirty six 10mil thermal vias, no air flow, and 1W power
dissipation. Refer to or Evaluation Board Application Note: AN-2074.
Note 4:
EN 55022:2006, +A1:2007, FCC Part 15 Subpart B: 2007. See 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
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
A) of 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 8:
Typical numbers are at 25°C and represent the most likely parametric norm.
