THERMAL CHARACTERISTICS
HEAT SINK - ESOIC PACKAGE
The HI-1570PSI/T/M all use a 20-pin thermally enhanced
SOIC package. The package include a metal heat sink
located on the bottom surface of the device. The heat
sink should be soldered down to the printed circuit board
for optimum thermal dissipation. The heat sink is also
electrically isolated and may be soldered to any
convenient power or ground plane.
RECOMMENDED TRANSFORMERS
The HI-1570 transceiver has been characterized for
compliance with the electrical requirements of MIL-STD-
1553 when used with the following transformers. Holt
