LT 8289总线仲裁器研制

The Analysis and Development of LT8289 Bus Arbiter

LT8289总线仲裁器是为8086/8088多重设备/多重处理系统配套的接口电路。它为多总线主设备系统以及远程方式下的8089 IOP提供总线仲裁,它还具有双极型的缓冲与驱动能力。该电路在工艺上采用了PI为介质的双层布线及薄层外延等技术。芯片面积3.0×3.1mm^2,元件数近900个。

The LT8289 Bus Arbiter is a bipolar Component for use with mediun to large iAX86, 88 multimaster/multi-processing systems. The 8289 provides system bus arbitration for systems with multiple bus masters, Such a, an 8086 CPU with 8089 IOP in its REMOTE mode, while providing bipolar buffering and drive capability. In technology, advanced processes of LSTTL are used in the circuits, such as two-layer interconnection, thin epitaxial and so on. The die size is 3.0×3.1mm^2. The number of elements is about 900.
