UC5601  
SCSI Active Terminator  
FEATURES  
DESCRIPTION  
The UC5601 provides precision resistive pull-up to a 2.9V reference for all  
18 lines in a Small Computer Systems Interface (SCSI) bus cable. The  
SCSI-2 standard recommends active termination at both ends of every ca-  
ble segment utilizing single ended drivers and receivers.  
Complies with SCSI, SCSI-2  
Standards  
10pF Channel Capacitance During  
Disconnect  
±
Internal circuit trimming is utilized, first to reduce resistor tolerances to 3%  
Active Termination for 18 Lines  
and then to adjust the regulator’s output voltage to insure termination cur-  
Logic Command Disconnects all  
Termination Lines  
±
rent accuracy of 3%.  
The UC5601 provides a disconnect feature which, upon a logic command,  
disconnects all terminating resistors, and turns off the regulator; greatly re-  
ducing standby power.  
Low Supply Current in Disconnect  
Mode  
Trimmed Regulator for Accurate  
Termination Current  
Other features include negative clamping on all signal lines, 20mA of active  
negation sink current capability, regulator current limiting, and thermal shut-  
down protection.  
Current Limit and Thermal  
Shutdown Protection  
This device is offered in low thermal resistance versions of the industry  
standard 28 pin wide body SOIC and PLCC, as well as a 24 pin DIL plastic  
package.
