... Application information The functional diagram here above presents a IEEE1284-A connector pinout and show how to connect the ST1284-01A8 in order to correctly terminate and filter the 17 signal lines. The IEEE1284-A connector is the PC standard for the host connection. Control and status lines (from 10 to 17) only require a pull-up resistor (R capacitor (C) ...

... ESD susceptibility. This test is described in the IEC 61000-4-2 and is already in place in Europe. This test requires that a device tolerates ESD events and remain operational without user intervention. The ST1284-01A8 is particularly optimized to perform ESD protection. ESD protection is based on the use of device which clamps at: V ...
