82C89  
CMOS Bus Arbiter  
March 1997  
Features  
Description  
• Pin Compatible with Bipolar 8289  
The Intersil 82C89 Bus Arbiter is manufactured using a self-  
aligned silicon gate CMOS process (Scaled SAJI IV). This cir-  
cuit, along with the 82C88 bus controller, provides full bus arbi-  
tration and control for multi-processor systems. The 82C89 is  
typically used in medium to large 80C86 or 80C88 systems  
where access to the bus by several processors must be coordi-  
nated. The 82C89 also provides high output current and capac-  
itive drive to eliminate the need for additional bus buffering.  
• Performance Compatible with:  
- 80C86/80C88 . . . . . . . . . . . . . . . . . . . . . . . . . .(5/8MHz)  
• Provides Multi-Master System Bus Control and  
Arbitration  
• Provides Simple Interface with 82C88/8288 Bus  
Controller  
Static CMOS circuit design insures low operating power. The  
advanced Intersil SAJI CMOS process results in perfor-  
mance equal to or greater than existing equivalent products  
at a significant power savings.  
• Synchronizes 80C86/8086, 80C88/8088 Processors  
with Multi-Master Bus  
• Bipolar Drive Capability  
• Four Operating Modes for Flexible System Configura- Ordering Information
