Gnd  
The ST1284-xxA8/T8 is a highly integrated termi-  
nation for enhanced high speed parallel ports. The  
integrated termination complies to the IEEE1284  
Standard recommendations and government  
EMC compatibility requirements. It is built around  
two basic cells. The first one (Cell 1) provides line  
termination, EMI filtering and ESD protection for  
the Strobe and Datalines while the second one  
(Cell 2) provides EMI filtering and ESD protection  
for the Control and Status lines. In addition,  
ST1284-xxA8 provides extra protection against  
ESD. When tested according to IEC61000-4-2,  
they withstand ±8kV contact discharges and  
±15kV air-discharges, thereby providing to the  
system the necessary robustness to meet up to  
level 4 of IEC61000-4-2, without the need for addi-  
tional ESD protection components. Cells 1 and 2  
are described in more detail in figures 1 and 2.
