description  
The VME bus bias generator provides current for up to 32 lines of active termination for a VME64 parallel bus.  
The VME standards require termination at both ends of the bus. The voltage regulator and internal logic circuits  
of these parts provide all the functionality and performance necessary to bias termination resistors for the VME  
bus. The VME bus bias generator sink current maintains regulation with all active negation drivers negated.  
Internal circuit trimming is used to trim the output voltage to a 1% tolerance. The UC563 regulator source/sink  
will provide better VME bus performance and work with active negation drivers. The regulator with resistor  
provides the bus with higher pullup current than passive termination. Other features include thermal shutdown  
and current limit for short circuit conditions. This device is available in low thermal resistance versions of the  
industry standard 8-pin power SOIC.
