Notes:
1. Enable inputs EN1 and EN2 can be used for multiplexing, for clock sync, or other output control. These inputs are
2. X = not applicable; H = Logic High; L = Logic Low.
3. When using the enable pin (EN) function, the output pin state goes into a high-impedance state when the EN pin is

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 Si845x is
operating in a noisy environment.
