Notes.  
1. One output at a time can be shorted to ground indefinitely.  
2. Both outputs are fused at between 0.5 Amp DC and 1.0 Amp DC to prevent an over-voltage fault from  
coupling onto the system power bus.

Thermal Management  
Device power dissipation varies greatly as a function of data rate, load capacitance, data duty cycle, and supply voltage.  
Proper thermal management is important in designs operating at the HI speed data rate (100KBS) with high capacitive  
loads and high data duty cycles.  
Power dissipation may be estimated from Table 5 “Power Dissipation Table”. Device power dissipation (Pd) is indicated  
for 100% data duty cycle with no word gap null times and should be adjusted for the appropriate data duty cycle (DC).  
Pd(application) = DC * [Pd(table) - 145mW] + 145mW, where DC is the application data duty cycle, Pd(table) is the Pd  
from the table for the indicated data rate and bus load, and 145mW is the quiescent power. The application’s data duty  
cycle (DC) for 100KBS operation is calculated as:  
DC = (total bits transmitted in 10 sec period / 1,000,000) =  
(32 x total ARINC words transmitted in 10 sec period / 1,000,000).  
Heat transfer from the IC package should be maximized. Use maximum trace width on all power and signal connections  
at the IC. Place vias on the signal/power traces close to the IC to maximize heat flow to the internal power planes. If  
possible, design a solid heat spreader land under and beyond the IC to maximize heat flow from the device.
