82C89

CMOS Bus Arbiter

FN2980

Rev 3.00

September 4, 2015

The Intersil 82C89 Bus Arbiter is manufactured using a self-

aligned silicon gate CMOS process (Scaled SAJI IV). This

circuit, along with the 82C88 bus controller, provides full bus

arbitration 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

coordinated. The 82C89 also provides high output current and

capacitive drive to eliminate the need for additional bus

buffering.

Features

• Pin Compatible with Bipolar 8289

• 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

performance 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 Configuration

Ordering Information

• Low Power Operation

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
