DS21S07A  
SCSI Terminator  
www.maxim-ic.com  
GENERAL DESCRIPTION  
PIN CONFIGURATIONS  
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 110termination resistors into  
a
monolithic IC. The DS21S07A can be electrically  
isolated from the SCSI bus without physical removal  
from the SCSI device.  
FEATURES  
Fully Compliant with SCSI-1, Fast SCSI, and  
Ultra SCSI

DS2107A
