DS2105

Fast SCSI and Ultra SCSI require the use of active ter-minations at both ends of every cable segment in aSCSI system with singleended drivers and receivers.
The DS2105 SCSI Terminator, which is fully compliantwith these standards, enables the designer to gain thebenefits of active termination: greater immunity to volt-age drops on the TERMPWR (TERMination PoWeR)line, enhanced highlevel noise immunity, intrinsicTERMPWR decoupling, and very low quiescent currentconsumption.

The DS2105, which integrates a regula-tor and nine precise switched 110 ohm termination re-sistors into a monolithic IC, is a functionally compatibleversion of the DS21S07A. With relaxed output currentand termination tolerances, the DS2105 is intended forhigh volume applications which require active termina-tion but not the high performance of the DS21S07AThe DS2105 is offered in both 300 mil and 150 mil SOICpackages.
