STANDARD TEST CONDITIONS
The DC Characteristics section below apply for the follow-
ing standard test conditions, unless otherwise noted. All
voltages are referenced to GND. Positive current flows into
the referenced pin. Standard conditions are as follows
(Figures 42 and 43):
s +4.5V < V_CC < +5.5V
s GND = 0V
