Note 1: An external 0.01µF bypass capacitor in parallel with a 0.1µF high frequency ceramic bypass
capacitor close (less than 2mm) to the package ground and supply voltage pin is required.
Note 2: A low input capacitance (<12pF), 10X attenuation factor, high impedance (>10Mohms), and
high bandwidth (>300MHz) passive probe is recommended.
Note 3: Capacitance value C
L
includes sum of all probe and fixture capacitance.
