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

(1) 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).
(2) Typical numbers are at 25°C and represent the most likely parametric normal.
