DESCRIPTION  
Fast SCSI and Ultra SCSI require the use of active terminations at both ends of every cable segment in a  
SCSI system with single-ended drivers and receivers. The DS21T07 SCSI Terminator, which is fully  
compliant with these standards, enables the designer to gain the benefits of active termination: greater  
immunity to voltage drops on the TERMPWR (TERMination PoWeR) line, enhanced high-level noise  
immunity, intrinsic TERMPWR decoupling, and very low quiescent current consumption. The DS21T07  
integrates a regulator and nine precise switched 110 ohms termination resistors into a monolithic IC. The  
DS21T07 can be electrically isolated from the SCSI bus without physical removal from the SCSI device.
