M8289

The Intel M8289 is a 5-volt-only bipolar component for use with medium to large M8086,M8088,M8089 and M80186 multimaster.multiprocessing systems.The M8289 provides system bus arbitration for systems with multiple bus masters,such as an M8086 CPU with capability.For new designs,see the M82289 bus arbiter data sheet.

Features of the M8289 can be summarized as:(1)provides multi-master system bus protocol;(2)synchronizes M8086,M8088,M8089 and M80186;(3)provides simple interface with M8288 bus controller;(4)military temperature range:-55 to +125(Tc);(5)four operating modes for flexible system configuration;(6)single +5V +/-10% power supply and (7)provides system bus arbitration for M8089 IOP in remote mode.

The absolute maximum ratings of the M8289 are:(1)case temperature under bias:-55 to +125;(2)storage temperature:-65 to 150;(3)voltage on any other pin to VSS:-0.5V to +7V;(4)all input voltages:-1.0V to +5.5V;(5)power dissipation:1.5W.
