GENERAL 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 DS21S07A 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
DS21S07A integrates a regulator and nine precise
switched
110
termination
monolithic IC. The DS21S07A can be electrically
isolated from the SCSI bus without physical removal
from the SCSI device.
