IEEE 1284 Parallel Port
ESD/EMI/Termination Network
PACSZ1284
2010 SCILLC. All rights reserved.
Publication Order Number:
May 2010 Rev. 3
PACSZ1284/D
Features
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
RoHS compliant (lead-free) finishing
Applications
Parallel Ports of PCs, printers, peripherals,
and Set-Top Boxes
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
±30kV contact
discharge, well beyond Level 4 of the IEC 61000-4-2
specification. All other pins are ESD-protected for
contact discharges up to
±8kV per IEC 61000-4-2.
There are two values available for pull-up resistor R1.
For the
PACSZ1284-02, R1
= 2.2kΩ; for the
PACSZ1284-04, R1 = 4.7kΩ.
The PACSZ1284 is housed in a 28-pin QSOP
package and is available with RoHS compliant lead-
free finishing.
