NOTES:
1. All voltages are referenced to ground. Currents flowing into device pins are positive. Currents out of
the device pins are negative.
2. I/O pins of fast mode devices will not obstruct SDA and SCL even if VCC is switched off.
3. ICC specified with SDA pin open, SCL = 400 kHz clock rate.
4. ISTBY specified with VCC at 5.0V and SDA, SCL = 5.0V.
