UCC5686 27 线路 2.7-5V LVD 端接器,用于 Ultra2 至 Ultra320 SCSI
              
The UCC5686 is a twenty-seven line active terminator for   low-voltage-differential (LVD) SCSI networks. This LVD SCSI-only design allows   the user to reach peak bus performance, while reducing system cost. The device   is designed as an active Y-terminator to improve the frequency response of the   LVD SCSI Bus. Designed with a 2-pF (typical) channel capacitance, the UCC5686   allows for minimal bus loading for a maximum number of peripherals. With the   UCC5686, the designer is able to comply with the Ultra2, Ultra3, Ultra160, and   Ultra320 SCSI specifications. The UCC5686 also provides a much-needed system   migration path for the ever improving SCSI system standards. 
              This device is available in the 64-pin low-profile QFP package for ease of   layout use
