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 (<12pF), 10X attenuation factor, high impedance (>10Mohms), and high bandwidth
(>300MHz) passive probe is recommended.
Note 3: Capacitance value CL includes sum of all probe and fixture capacitance.
Note 4: Resistance value RL is shown in Table 1. See applicable specification sheet for 'Load Drive Capability'.
Note 5: All diodes are MMBD7000, MMBD914, or equivalent.
