- 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 input capacitance (<12pF), 10X Attentuation 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 I. See applicable specification
sheet for ‘Load Drive Capability’.
- Note 5: All diodes are MMBD7000, MMBD914, or equivalent.
