Note 1. The exposed pad on the bottom surface of the package must be open or connected to the
ground.
Note 2. All digital input pins must not be allowed to float. If analog input pins are not used, leave them
open.
Note 3. The description of (Internal Pull-down) above indicates the pin status just after power-down is
released (PDN pin = “H”).
