PACSZ1284
IEEE 1284 Parallel Port
ESD/EMI/Termination
Network
Product Description
The PACSZ1284 combines EMI filtering, ESD protection, and
signal termination in a single QSOP package for parallel port
interfaces complying to the IEEE 1284 standard.
The PACSZ1284 provides a complete parallel port termination
solution. It integrates the equivalent of 60 discrete components,
making it ideal for space critical applications. The pins of the device
which connect to the parallel port are protected to ? 30 kV contact
discharge, well beyond Level 4 of the IEC 61000 ? 4 ? 2 specification.
All other pins are ESD ? protected for contact discharges up to ? 8 kV
per IEC 61000 ? 4 ? 2.
There are two values available for pull ? up resistor R1. For the
PACSZ1284 ? 02, R1 = 2.2 k W ; for the PACSZ1284 ? 04, R1 = 4.7 k W .
The PACSZ1284 is housed in a 28 ? pin QSOP package and is
available with RoHS compliant lead ? free finishing.
