6.5 Electrical Characteristics
Unless otherwise stated, the following conditions apply: VPVIN = VAVIN= 5 V, TJ = 25°C. Minimum and maximum limits are
specified through test, design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C
and are provided for reference purposes only.
