Obsolete Device  
SLUS349B − DECEMBER 1994 − REVISED APRIL 2005  
FEATURES  
DESCRIPTION  
D
Complies with SCSI, SCSI−2 and SPI−2 Single  
Ended Standards  
The UCC5614 provides 9 lines of active termination for  
a small computer system’s interface (SCSI) parallel  
bus. The SCSI standard recommends active  
termination at both ends of the cable segment.  
D
2.7-V to 5.25-V Operation  
D
1.8-pF Channel Capacitance during  
Disconnect  
The UCC5614 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 2.7-V reference. During disconnect the supply  
current is typically only 0.5 µA, which makes the device  
attractive for battery powered systems.

Drivers  
The UCC5614 is designed with an ultra low channel  
capacitance of 1.8 pF, which eliminates effects on signal
