Thermal Data
Table 39 shows the package thermal data for the GT-48004A. Galileo recommends the use of heatsink for most sys-
tems, especially those with little or no airflow. Please check with Galileo if you are in doubt as to thermal considerations
for your system.
1. Operating the device for extended periods of time at the maximum junction temperature may
cause permanent damage to this device, resulting in functional or reliability type failures.
