DS21T09S/T&R Overview
A 9 termination consists of terminating transmission lines with a device matching the line's characteristic impedance. The 28-SOIC (0.295, 7.50mm Width) is well known in the electronic industry due to its low package cost. The Packaging follows Tape & Reel (TR)'s materials. Mounting it on a PCB is done with Surface Mount. It is recommended that the Operating Temperature not exceed 0°C~70°C. It is a SCSI-qualified material for standard applications. There is a 4V~5.5V Supply Voltage provided to ensure normal operation. For finding related parts, you can use Base Part Number DS21T09. The supplier uses 28-SOIC as a device package for its devices. Operating it should result in a warmer temperature than 0°C. As a result, it operates at the maximum operating temperature of 70°C in order to provide maximum reliability.
