description  
The UCC5610 provides 18 lines of active termination for a SCSI (small computer systems interface) parallel  
bus. The SCSI standard recommends active termination at both ends of the cable.  
The UCC5610 is ideal for high performance 3.3-V SCSI systems. The key features contributing to such low  
operating voltage are the 0.1-V drop-out regulator and the 2.75-V reference. During disconnect the supply  
current is typically only 0.5 µA, which makes the IC attractive for battery powered systems.  
The UCC5610 is designed with an ultralow-channel capacitance of 1.8 pF, which eliminates effects on signal  
integrity from disconnected terminators at interim points on the bus.  
The UCC5610 can be programmed for either a 110-or 2.5-ktermination. The 110-termination is used for  
standard SCSI bus lengths and the 2.5-ktermination is typically used in short bus applications. When driving  
the TTL compatible DISCNCT pin directly, the 110-termination is connected when the DISCNCT pin is driven  
low, and disconnected when driven high. When the DISCNCT pin is driven through an impedance between  
80 kand 150 k, the 2.5-ktermination is connected when the DISCNCT pin is driven low, and disconnected  
when driven high.
