NOTES:
6. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
7. Fluorescent light is substituted by a white LED during production.
8. The voltage threshold levels of the SDA and SCL pins are VDD dependent: V_TL = 0.35*V_DD. V_TH = 0.65*V_DD.
