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.
