NOTES:

6. Cover glass assumes fixed infrared/visible light transmissivity ratio of 10.

7. An 850nm infrared LED is used in production test for proximity/IR sensitivity testing.

8. All parameters in the I2C Electrical Specifications table are guaranteed by design and simulation.

9. Cb is the capacitance of the bus in pF.

10. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization

and are not production tested.

I2C Electrical Specifications For SCL and SDA unless otherwise noted, VDD = 3V, TA = +25°C (Note 8). (Continued)
