The ST1284-xxA8/T8 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 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 additional ESD protection components. Cells 1 and 2 are described in more detail in figures 1 and 2.
