ST1284：17-line EMI filter and ESD protection with Termination and R pull-up for ST1284 interfaces

The ST1284 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 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.
