UCC5606  
9-Line 3-5 Volt SCSI Active Terminator, Reverse Disconnect  
FEATURES  
DESCRIPTION  
Complies with SCSI, SCSI-2 and  
SCSI-3 Standards  
The UCC5606 provides 9 lines of active termination for a SCSI (Small  
Computer Systems Interface) parallel bus. The SCSI standard recom-  
mends active termination at both ends of the cable segment.  
2.7V to 7V Operation  
The UCC5606 is ideal for high performance 3.3V SCSI systems. The key  
features contributing to such low operating voltage are the 0.1V drop out  
regulator and the 2.7V reference. The reduced reference voltage was  
necessary to accommodate the lower termination current dictated in the  
SCSI-3 specification. During disconnect the supply current is typically  
only 1µA, which makes the IC attractive for battery powered systems.

Mode  
110 Ohm/2.5k Programmable  
Termination  
The UCC5606 is designed with an ultra low channel capacitance of  
1.8pF, which eliminates effects on signal integrity from disconnected ter-  
minators at interim points on the bus.  
Completely Meets SCSI Hot Plugging  
-400mA Sourcing Current for  
Termination  
The UCC5606 can be programmed for either a 110 ohm or 2.5k ohm ter-  
mination. The 110 ohm termination is used for standard SCSI bus lengths  
and the 2.5k ohm termination is typically used in short bus applications.  
When driving the TTL compatible DISCNCT pin directly, the 110 ohm ter-  
mination is connected when the DISCNCT pin is driven high, and discon-  
nected when low. When the DISCNCT pin is driven through an  
impedance between 80k and 150k, the 2.5k ohm termination is con-  
nected when the DISCNCT pin is driven high, and disconnected when
