Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
3. All typical values are measured at TA = 25°C and VCC = 3.3 V, unless stated otherwise.
