Product Description
California Micro Devices’ PACS1284 Parallel Port Ter-
mination Network provides a complete integrated solu-
tion for the entire IEEE 1284 interface in a single
QSOP package.
To support the bi-directional transfer data rates of
enhanced high-speed parallel ports, the IEEE 1284
Standard recommends a combined termination/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 requirements on the parallel port. The
California Micro Devices PACS1284 addresses all
these requirements by providing a seventeen-line IEEE
1284-compliant network in a thin film integrated circuit.
The device provides a complete parallel port termina-
tion solution for space critical applications by integrat-
ing a total of 60 discrete components. In addition, all
the I/O pins are ESD protected for contact discharges
up to
output pins having the highest probability of ESD pulse
exposure protected to
the necessary robustness for the port’s application
environment.
The PACS1284 is manufactured in a 28-pin QSOP
package and is available with optional lead-free finish-
ing.
