Hi,
For TXB0106, there RGY package, there is an "Exposed Center Pad" at the center.
It is not labeled with a pin number, not listed in pin description, and not
shown in example circuit schematics.
However, only in the first page of the datasheet SCES709, below the drawing of
RGY package, there is a sentence:
SCES1709, page 1 said:
The exposed center pad, if used, must be connected as a secondary ground or left electrically open.
In contrast, a great many other chips with similar land pattern specified that the central pad shall be connected to GND, usually for thermal dissipation.
Does "secondary" refer to GND, and should the center pad be connected to [pin 9, GND]?
