PACS1284  
IEEE 1284 ECP/EPP Termination Network  
Product Description  
Features  
Single chip IEEE 1284 parallel port termination  
28-pin QSOP package, smallest physical  
solution  
17 terminating lines in a single package  
In-system ESD protection to 8KV, HBM  
In-system ESD protection to 4KV per  
IEC 61000-4-2  
Protects downstream devices to 30V  
Lead-free version available  
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  
Applications  
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.  
ECP/EPP Parallel Port termination

Notebook and Desktop computers  
Engineering Workstations and Servers  
The PACS1284 is manufactured in a 28-pin QSOP  
package and is available with optional lead-free finish-  
ing.
