The DS21T05S is a SCSI Terminator IC manufactured by Analog Devices / Maxim Integrated, suitable for high-volume applications. It is fully compliant with SCSI-1, Fast SCSI, and Ultra SCSI standards, providing active termination for nine signal lines. The device features laser-trimmed 110-ohm termination resistors with a 5% tolerance and operates within a voltage range of 4V to 5.5V.
Designed for surface mounting, the DS21T05S comes in a 16-SOIC package with dimensions of 7.50mm width. It operates reliably within a temperature range of 0°C to 70°C. The IC integrates a regulator and nine precise-switched termination resistors into a monolithic IC, offering benefits such as greater immunity to voltage drops on the TERMPWR line and enhanced high-level noise immunity.
This SCSI terminator is functionally compatible with the DS21T07, making it a cost-effective solution for applications requiring active termination without the highest performance demands. It supports actively negated SCSI signals and includes onboard thermal shutdown circuitry for protection. The power-down mode allows for isolation of termination resistors from the bus when not in use, contributing to low quiescent current consumption.
The operating voltage range for the DS21T05S is 4V to 5.5V.
The operating temperature range for the DS21T05S is 0°C to 70°C.
