Description

Fast SCSI and Ultra SCSI require the use of active terminations at both ends of every cable segment in a SCSI system with singleended drivers and receivers. The DS21T16 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 highlevel noise immunity, intrinsic TERMPWR decoupling, and very low quiescent current consumption. The DS21T16 integrates a regulator and nine precise switched 110 ohms termination resistors into a monolithic IC. The DS21T16 can be electrically isolated from the SCSI bus without physical removal from the SCSI device.
