DESCRIPTION

· The DS21T07 SCSI Terminator is fully compliant with SCSI-1, Fast SCSI, and Ultra SCSI standards, ensuring active termination at both ends of every cable segment in a SCSI system with single-ended drivers and receivers.

· It integrates a regulator and nine precise switched 110 ohms termination resistors into a monolithic IC, offering enhanced noise immunity and low quiescent current consumption.

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

FEATURES

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

· Backward compatible with DS2107, DS2107A, and DS21S07.

· Provides active termination for nine signal lines with laser-trimmed 110 ohms resistors (2% tolerance).

· Includes a low dropout voltage regulator and power-down mode to isolate termination resistors from the bus.

· Supports actively negated SCSI signals and features onboard thermal shutdown circuitry.

· Available in 16-pin plastic SOIC (DS21T07S) and 20-pin plastic TSSOP (DS21T07E) packages.

APPLICATIONS

· Ideal for SCSI systems requiring active termination to enhance signal integrity and noise immunity.

· Suitable for applications where SCSI bus hot-plug compatibility and low power consumption are critical.

· Used in environments demanding precise termination resistors and robust thermal management.
