When the ATA663254 in its special 8-Lead SOIC

package (fused lead frame to pin 5) is being soldered

on to the PCB, it is mandatory to connect pin 5 with a

wide GND plate on the printed board to get a good heat

sink.

Figure 1-13 shows the safe operating area of the

ATA663254 in the 8-Lead SOIC package.
