... Zo) Figure 3. Transformer Coupled Test Circuits HEAT SINK - ESOIC & CHIP-SCALE PACKAGE Both the HI-1573PSI/T/M and HI-1574PSI/T/M use a 20- pin thermally enhanced SOIC package. The HI- 1573PCI/T and HI-1574PCI/T use a plastic chip-scale package. These packages include a metal heat sink located on the bottom surface of the device. This heat sink should be soldered down to the printed circuit board for optimum thermal dissipation ...
