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 ensured specifications and test conditions, see the Electrical Characteristics.
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 ensured 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 = V EN = 3.3V, unless otherwise indicated in the conditions column.

Min and Max limits are 100% production tested at an ambient temperature (T A ) of 25°C. Limits over the operating temperature range are
ensured through correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality
Level (AOQL).
Typical numbers are at 25°C and represent the most likely parametric normal.
θ JA measured on a 2.25” x 2.25” (5.8 cm x 5.8 cm) four layer board. Refer to PCB Layout Diagrams or Evaluation Board Application
