NOTE: The XRT7302 is assembled in a thermally enhanced
package with an integral Copper Heat Slug. The Heat Slug
is solder plated on the bottom of the package and is electri-
cally connected to the Ground connections of the device.
This Heat Slug can be soldered to the mounting board if
desired, but must be isolated from any VDD connections.
