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 a
single-ended
drivers
ST21S07A SCSI terminator, which is fully
and
reveivers.
The
compliant with these standands, enables the
designer to gain the benefits of active termination:
greater immunity to voltages drop on the
TERMPWR
(TERMination
enhanced high level noise immunity, intrinsic
TERMPWR decouplig, and very low quiescent
current consumption.
The ST21S07A integrates a regulator and nine
precise switched 110
termination resistors into a
monolithic IC. The ST21S07A can be electrically
isolatesd from the SCSI bus without physical
removal from the SCSI device.
