1. A 0.1 μF low frequency tantalum bypass capacitor in parallel with a 0.01 μF high frequency ceramic capacitor is recommended.
2. Figure 2 defines the waveform parameters. Figure 3 illustrates the standard test conditions under which these parameters are specified and
tested.
3. Duty cycle is defined as (on time÷period), with VS = VDD/2, per figure 2. Duty cycle is measured with a 15pf load per figure 3.
4. Other frequencies may be available, please contact factory.
