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.
