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

4KV per the Human Body Model (HBM), with the

output pins having the highest probability of ESD pulse

exposure protected to

8KV (HBM), thereby providing

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.
