DESCRIPTION
The SCSI–2 and SCSI–3 standards recommend the
use of active terminations at both ends of every cable
segment in a SCSI system with single–ended drivers
and receivers. The DS2114 SCSI Terminator, which is
fully compliant with these standards, enables the de-
signer to gain the benefits of active termination: greater
immunity to voltage drops on the TERMPWR (TER-
Mination PoWeR) line, enhanced high–level noise im-
munity, intrinsic TERMPWR decoupling, and very low
quiescent current consumption. The DS2114 integrates
a regulator and nine precise 110 ohms termination re-
sistors into a monolithic IC. The DS2114 is intended for
cable end terminator assemblies and devices where the
terminators do not need to be isolated from the SCSI
bus.
