description  
The UC5603 provides 9 lines of active termination for a SCSI (Small Computers Systems Interface) parallel bus.  
The SCSI standard recommends active termination at both ends of the cable segment.  
The UC5603 provides a disconnect feature which, when opened or driven high, will disconnect all terminating  
resistors, and disables the regulator; greatly reducing standby power. The output channels remain high  
impedance even without Termpwr applied. A low channel capacitance of 6 pF allows units at interim points of  
the bus to have little to no effect on the signal integrity.  
Functionally the UC5603 is similar to its predecessor, the UC5601 − 18 line Active Terminator. Several electrical  
enhancements were incorporated in the UC5603, such as a sink/source regulator output stage to accommodate  
all signal lines at 5 V, while the regulator remains at its nominal value, reduced channel capacitance to 6 pF  
typical, and as with the UC5601, custom power packages are utilized to allow normal operation at full power  
conditions (1.2 watts).
