Product Description
California Micro Devices’ PACS1284 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 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 com-
plete parallel port termination solution for space critical
applications by integrating a total of 43 discrete compo-
nents. 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 environ-
ment.
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.
