Note:

Testing conditions: Typical values are defined at Tamb = 25°C and VDD1 = VDD2 = 3 V, minimum and

maximum limits applies to the full temperature range (Tested in production at Tamb = 25°C and the

limits in the full temperature range are guaranteed by characterization on a limited quantity of samples),
