Output Pin

(1) The tab on the bottom of the package enhances thermal performance and is electrically connected to GND (substrate

level). The tab is recommended to connect to the ground plane on the board. Otherwise it may be left floating.

(2) DOUT pin should be pulled-up to an external voltage level.
