UCC5672  
Multimode (LVD/SE) SCSI 9 Line Terminator  
FEATURES  
DESCRIPTION  
• Auto Selection Multi-Mode Single  
Ended or Low Voltage Differential  
Termination  
The UCC5672 Multi-Mode Low Voltage Differential and Single Ended Ter-  
minator is both a single ended terminator and a low voltage differential ter-  
minator for the transition to the next generation SCSI Parallel Interface  
(SPI-3). The low voltage differential is a requirement for the higher speeds  
at a reasonable cost and is the only way to have adequate skew budgets.  
• 2.7V to 5.25V Operation  
• Differential Failsafe Bias  
The automatic mode select/change feature switches the terminator be-  
tween Single Ended or LVD SCSI Termination, depending on the bus  
mode. If the bus is in High Voltage Differential Mode, the terminator lines  
transition into a High Impedance state.  
• Built-in SPI-3 Mode Change Filter/  
Delay  
• Meets SCSI-1, SCSI-2, Ultra2 (SPI-2  
LVD), Ultra3/Ultra160 (SPI-3) and  
Ultra320 (SPI-4) Standards  
The UCC5672 is SPI-4, SPI-3, SPI-2, and SCSI-2 compliant. This device  
is offered in a 28 pin TSSOP package to minimize the footprint. The  
UCC5672 is also available in a 36 pin MWP package.  
• Supports Active Negation  
• 3pF Channel Capacitance
