Notes:
(1) LED matching applies to current sinks set to the same current only. Matching is calculated as follows:

(2) Guaranteed by design.
(3) The total quiescent current in Sleep Mode will increase when serial bus activity occurs, and with the clock frequency of that bus activity.
(4) When the junction temperature exceeds the Over Temperature (OT) threshold, the device will enter Sleep Mode with the contents of all registers retained.
The device will exit Sleep Mode and re-commence normal operation as soon as the junction temperature drops by more than the OT hysteresis.
