Electrical Characteristics
Specifications in standard typeface are for T_J = 25°C, and those in boldface type apply over the full operating junction temperature
range.(Note 3). Typical values represent the most likely parametric norm at T_J = 25°C, and are provided for reference purposes
only. Unless otherwise stated the following conditions apply: V_D=V_A=5V.
