Description
GENERAL 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 DS21S07A 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 DS21S07A integrates a regulator and nine precise switched 110Ω termination resistors into a monolithic IC.
The DS21S07A 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 and DS2107A
• Provides Active Termination for Nine Signal Lines
• Laser-Trimmed 110Ω Termination Resistors Have 2% Tolerance
• Low Drop-Out Voltage Regulator
• Power-Down Mode Isolates Termination Resistors from the Bus
• SCSI Bus Hot Plug Compatible
• Fully Supports Actively Negated SCSI Signals
• On-Board
Thermal Shutdown Circuitry
• 16-Pin Plastic SO (DS21S07AS) and 20-Pin Plastic TSSOP (Thin Shrink Small Outline Package) (DS21S07AE)
Alternatives

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