MAIN APPLICATIONS
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
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.
