Description
Fast SCSI and Ultra SCSI require the use of active terminations at both ends of every cable segment in a SCSI system with single-ended drivers and receivers.
The DS21T07 SCSI Terminator, which is fully compliant with these standards, enables the designer to gain the benefits of active termination: greater immunity to voltage drops on the TERMPWR (TERMination PoWeR) line, enhanced high-level noise immunity, intrinsic TERMPWR decoupling, and very low quiescent current consumption.
The DS21T07 integrates a regulator and nine precise switched 110 ohms termination resistors into a monolithic IC.
The DS21T07 can be electrically isolated from the SCSI bus without physical removal from the SCSI device.
FEATURES
• Fully compliant with SCSI–1, Fast SCSI and Ultra SCSI
• Backward compatible to the DS2107, DS2107A, and DS21S07
• Provides active termination for nine signal lines
• Laser–trimmed 110 ohms termination resistors have 2% tolerance
• Low dropout voltage regulator
• Power–down mode isolates termination resistors from the bus
• SCSI bus hot–plug compatible
• Fully supports actively negated SCSI signals
• Onboard thermal shutdown circuitry
• 16–pin plastic SOIC (DS21T07S) and 20–pin plastic TSSOP (Thin Shrink Small Outline Package) (DS21T07E)
Alternatives

Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
