Description
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.
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.
