DS21T06S 28-Pin SOIC (300-mil)

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. Ultra SCSI requires support of active negation and

hot plugging. The DS21T06 is fully compliant with these standards.

The DS21T06 integrates a low dropout regulator and 18 precise switched 110 ohms termination resistors

into a 28-pin 300-mil SOIC package.

Active termination provides 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. One DS21T06 can be used to terminate the Narrow SCSI bus, or a

DS21T07 can be used with a DS21T06 for termination of a Wide SCSI bus.
