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 V

pin is required.

Note 2: A low capacitance (<12pF), 10X attenuation factor, high impedance (>10Mohms), and high bandwidth

(>300MHz) passive probe is recommended.

Note 3: Capacitance value C

includes sum of all probe and fixture capacitance.
