82C89
CMOS Bus Arbiter
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.
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.

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.
*Pb-free PDIPs can be used for through hole wave solder processing
only. They are not intended for use in Reflow solder processing
applications.
