Electrical Characteristics (continued)
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 specified 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.
