Note 1: An external 0.1µF low frequency tantalum bypass capacitor in parallel with a 0.01µF high frequency
ceramic bypass capacitor close to the package ground and VDD pin is required.
Note 2: A low capacitance (10Mohms), and high bandwidth
(>300MHz) passive probe is recommended.
Note 3: Capacitance value CL includes sum of all probe and fixture capacitance.
