NOTES:
1. All voltages are referenced to ground.
2. ISTBY specified with for VCC equal 3.0V and 5.0V and control port logic pins are driven to the
appropriate logic levels. Appropriate logic levels specify that logic inputs are within a 0.5V of
ground or VCC for the corresponding inactive state.
3. I/O pins of fast mode devices must not obstruct the SDA and SCL lines if VCC is switched off.
4. Address Inputs, A0, A1, and A2, should be tied to either VCC or GND depending on the desired
address selections.
5. ISTBY specified with for VCC equal 3.0V and 5.0V and control port logic pins are driven to the
appropriate logic levels. Appropriate logic levels specify that logic inputs are within a 0.5V of
ground or VCC for the corresponding inactive state.
