{For the UCC5687, Pin 47 is DISCNCT1 and Pin 48 is DISCNCT2.  
description  
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.  
Single-ended (SE) and high-voltage differential (HVD) SCSI drivers are not supported.
