17 EMI filters
17 ESD protectors yielding protection to 30kV
contact discharge, per IEC 61000-4-2 specification
17 terminators with choice of resistor values
28-pin QSOP package
Lead-free version available
Product Description
The PACSZ1284 combines EMI filtering, ESD protec-
tion, 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 ter-
mination solution. It integrates the equivalent of 60 dis-
crete components, making it ideal for space critical
applications. The pins of the device which connect to
the parallel port are protected to 30kV contact dis-
charge, well beyond Level 4 of the IEC 61000-4-2
specification. All other pins are ESD-protected for con-
tact discharges up to 8kV per IEC 61000-4-2.
There are three available values for pull-up resistor R1.
For the PACSZ1284-01, R1 = 1k鈩? for the PACSZ1284-
02, R1 = 2.2k鈩? for the PACSZ1284-04, R1 = 4.7k鈩?/div>

technology provides high reliability and low
cost through manufacturing efficiency. the PACSZ1284
is silicon-based and has the same reliability character-
istics as today鈥檚 integrated circuits.
