DS21T06S 28–PIN SOIC (300 MIL)
DESCRIPTION
Fast SCSI and Ultra SCSI require the use of active ter-
minations 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
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.
