DESCRIPTION

· The DS21T07 SCSI Terminator is fully compliant with SCSI-1, Fast SCSI, and Ultra SCSI standards, ensuring active termination for nine signal lines.

· It integrates a regulator and nine precise 110 ohms termination resistors, enhancing immunity to voltage drops and high-level noise.

· The device supports SCSI bus hot-plug compatibility and can be electrically isolated without physical removal.

FEATURES

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

· Backward compatible with DS2107, DS2107A, and DS21S07.

· Laser-trimmed 110 ohms termination resistors with 2% tolerance.

· Low dropout voltage regulator and power-down mode for bus isolation.

· Onboard thermal shutdown circuitry and support for actively negated SCSI signals.

· Available in 16-pin SOIC and 20-pin TSSOP packages.

APPLICATIONS

· Ideal for SCSI systems requiring active termination at both ends of every cable segment.

· Suitable for environments needing enhanced noise immunity and low quiescent current consumption.

· Used in systems where SCSI bus hot-plug compatibility is essential.
