* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may aect device reliability.
Note 1. All voltages are with respect to GND.

Notes
1. Values are shown at the VDD pin and do not include current through the IR LED.
2. Sleep state occurs when PON = 0 and I2C bus is idle. If Sleep state has been entered as the result of operational ow, SAI = 1, PON will be high.
