DS21T07S Active SCSI Terminator For Stable Cable Signaling

DS21T07S is intended for SCSI designs that need active termination at cable ends to control reflections and reduce noise sensitivity. In single-ended SCSI systems, proper termination is a core requirement for dependable data transfer, especially as cable length and device count increase. DS21T07S integrates a regulator and nine switched termination resistors, providing a compact way to terminate multiple active signal lines with consistent electrical behavior. That integration helps reduce discrete parts, simplifies layout, and supports cleaner edge behavior at the bus. Use DS21T07S in disk subsystems, embedded storage backplanes, and legacy instrumentation where SCSI remains in service. Place the device close to the connector and follow the recommended TERMPWR and decoupling practices. Request a quote for DS21T07S.
