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.
