DESCRIPTION

· The DS21T05 is a SCSI Terminator fully compliant with SCSI-1, Fast SCSI, and Ultra SCSI standards.

· It integrates a regulator and nine precise-switched 110-ohm termination resistors into a monolithic IC.

· Designed for high volume applications requiring active termination, it is functionally compatible with the DS21T07 but with relaxed output current and termination tolerances.

· It provides active termination for nine signal lines, enhancing immunity to voltage drops and high-level noise.

FEATURES

· Fully compliant with SCSI-1, Fast SCSI, and Ultra SCSI standards.

· Laser-trimmed 110-ohm termination resistors with 5% tolerance.

· Low dropout voltage and power-down mode to isolate termination resistors from the bus.

· SCSI bus hot-plug compatible and fully supports actively negated SCSI signals.

· Onboard thermal shutdown circuitry for enhanced safety.

APPLICATIONS

· High volume applications requiring active termination in SCSI systems.

· Systems with single-ended drivers and receivers needing active terminations at both ends of every cable segment.

· Applications where enhanced immunity to voltage drops and high-level noise is critical.
