PACKAGE AND THERMAL CONSIDERATIONS

The 33742 is a standard surface mount SOIC 28 package. In

order to improve the thermal performances of the SOIC 28

package, eight terminals are internally connected to the lead

frame and are used for heat transfer to the printed circuit board.

APPLICATIONS

Figure 28 shows a typical 33742 application.
