... Because the input thresholds of the ADuM3100 are at voltages other than the 50% level of typical input signals, the measured propagation delay and pulse-width distortion can be affected by slow input rise/fall times. See the System-Level ESD Considerations and Enhancements section and Figure 13 to Figure 17 for information on the impact of given input rise/fall times on these parameters ...

... APPLICATIONS PC BOARD LAYOUT The ADuM3100 digital isolator requires no external interface circuitry for the logic interfaces. A bypass capacitor is recommended at the input and output supply pins. The input bypass capacitor can conveniently connect between Pin 3 and Pin 4 (see Figure 12). Alternatively, the bypass capacitor can be located between Pin 1 and Pin 4 ...
