DESCRIPTION
The SCSI- 2 and SCSI- 3 standards remend 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 pliant with these standards, enables the designer to gain the benefits of active termination: greater immunity to voltage drops on the TERMPWR (TERMination Po We R) line, enhanced high- level noise immunity, intrinsic TERMPWR decoupling, and very low quiescent current consumption.
