The DS21T05Z is a SCSI Terminator IC manufactured by Dallas Semiconductor, designed for high-volume applications requiring active termination in SCSI systems. It is fully compliant with SCSI-1, Fast SCSI, and Ultra SCSI standards.
This component provides active termination for nine signal lines using laser-trimmed 110-ohm resistors with a 5% tolerance. It features a low dropout voltage and onboard thermal shutdown circuitry for reliability. The device supports actively negated SCSI signals and is SCSI bus hot-plug compatible.
Functionally compatible with the DS21T07, the DS21T05Z integrates a regulator and nine precise-switched termination resistors. It is available in a 16-pin plastic narrow SOIC package, suitable for surface mount applications. The power-down mode allows the termination resistors to be isolated from the bus, effectively removing the device from the circuit when not needed.
Designed for enhanced immunity to voltage drops on the TERMPWR line and improved high-level noise immunity, the DS21T05Z offers intrinsic TERMPWR decoupling and very low quiescent current consumption. Its design enables designers to gain the benefits of active termination in SCSI systems.
