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 is driven to a logic low state when the EN pin is disabled

internally pulled-up to local VDD by a 3 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 Si845x is
operating in a noisy environment.
(EN = 0) in Revision A. Revision B outputs go into a high-impedance state when the EN pin is disabled (EN = 0). See
