Product Description
California Micro Devices’ PACS1284-06 Parallel Port
Termination Network provides a complete integrated
solution for the entire IEEE 1284 interface in a single
QSOP package.
Advanced, enhanced high-speed parallel ports, con-
forming to the IEEE 1284 standard, are used to provide
communications with external devices such as tape
back-up drives, ZIP drives, printers, parallel port SCSI
adapters, external LAN adapters, scanners, video
capture, and other PC peripherals. These advanced
ports support bi-directional transfers to 2MB/sec. To
effectively support these higher transfer data rates, the
IEEE 1284 standard recommends a combined termina-
tion, pull-up filter network between the driver/receiver
and the cable at both ends of the parallel port interface.
In addition, government EMC compatibility requirements
impose strict filtering on the parallel port. California
Micro Devices’ PACS1284-06 Parallel Port Termination
Network addresses all of these requirements by provid-
ing a seventeen line, IEEE 1284 compliant network in a
thin film integrated circuit. The device provides a
complete parallel port termination solution for space
critical applications by integrating a total of 43 discrete
components. In addition, all I/O pins are ESD
protected for contact discharges up to 4KV per the
Human Body Model. However, the output pins of the
device which have the highest probability of exposure
to ESD pulses are protected to 8KV, HBM, thereby
providing the necessary robustness for the port’s
application environment.
California Micro Devices’ P/Active technology provides
high reliability and low cost through manufacturing
efficiency. The resistors and capacitors are fabricated
using proprietary state-of-the-art thin film technology.
California Micro Devices’ solution is silicon-based and
has the same reliability characteristics as today’s
integrated circuits.
