DS2114集成电路（IC）的信号端接器规格书PDF中文资料

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 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 DS2114 integrates a regulator and nine precise 110 ohms termination resistors 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.
