Description
The ST1284-01A8 is a highly integrated
termination 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 data lines while the
second one (cell 2) provides EMI filtering and
ESD protection for the Control and Status lines.
In addition, ST1284-01A8 provides extra
protection against ESD. When tested according to
IEC 61000-4-2, they withstand ±8 kV contact
discharges and ±15 kV air discharges, thereby
providing to the system the necessary robustness
to meet up to level 4 of IEC 61000-4-2, without the
need for additional ESD protection components.
