UC5607  
Plug and Play, 18-Line SCSI Active Terminator  
FEATURES  
DESCRIPTION  
Complies with SCSI and SCSI-2  
Standards  
The UC5607 provides 18 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.  
8pF Channel Capacitance during  
Disconnect  
The UC5607 provides a low disconnect feature which will disconnect all  
terminating resistors, and will disable the regulator, greatly reducing  
standby power. The output channels remain high impedance even without  
Termpwr applied.  
SCSI Plug and Play, Dual Low  
Disconnect, Logic Low Command  
Disconnects All Termination Lines  
The UC5607 terminator is specially designed with two disconnect pins for  
full SCSI Plug and Play (PnP) applications.  
Meets SCSI Hot Plugging Capability  
-650mA Sourcing Current for  
Termination  
Custom power packages are utilized to allow normal operation at full  
power conditions (2 Watts).  
+200mA Sinking Current for Active  
Negation  
Internal circuit trimming is utilized, first to trim the impedance to a 7% tol-  
erance, and then most importantly, to trim the output current to a 7% toler-  
ance, as close to the max SCSI spec as possible, which maximizes noise  
margin in fast SCSI operation.  
200µA Supply Current in Disconnect  
Mode  
Other features include thermal shutdown and current limit.  
Trimmed Termination Current to 7%  
Trimmed Impedance to 7%  
This device is offered in low thermal resistance versions of the industry  
standard 28 pin wide body SOIC, and 28 pin PLCC, as well as 24 pin DIP.  
Provides Active Termination for 18  
Lines
