Notes:
1. Enable inputs EN1 and EN2 can be used for multiplexing, for clock sync, or other output control. EN1, EN2 logic
operation is summarized for each isolator product in Table 13. These inputs are internally pulled-up to local VDD by a
2 μA current source allowing them to be connected to an external logic level (high or low) or left floating. To minimize
noise coupling, do not connect circuit traces to EN1 or EN2 if they are left floating. If EN1, EN2 are unused, it is
recommended they be connected to an external logic level, especially if the Si86xx is operating in a noisy environment.
2. X = not applicable; H = Logic High; L = Logic Low.
3. When using the enable pin (EN) function, the output pin state is driven into a high-impedance state when the EN pin is
disabled (EN = 0).
