EXP-PAD

(Note 1) Dispose a bypass capacitor as close as possible to the IC.

(Note 2) Use the NC pin as open pin.

(Note 3) If there is a device falls sharply among other devices connected to the SDA, SCL and INT pins, it might generate undershoot and the pin voltage might

be the ground potential or below. When the undershoot occurs, must take a measure like adding a capacitor near to the pin of the device concerned.
