DS21T07E/T&R Overview
Termination with a 9 device, which matches the transmission line's characteristic impedance, is considered a 9 termination. Because of its low package cost, the 20-TSSOP (0.173, 4.40mm Width) is widely used in the electronic industry. Tape & Reel (TR)'s packaging is made of the same materials. Surface Mount is used for mounting it on a PCB. A maximum operating temperature of 0°C~70°C should not be exceeded. The material is SCSI, LVD, SE-qualified for standard applications. In order to maintain normal operation, there is a 4V~5.5V Supply Voltage provided. You can find related parts by using Base Part Number DS21T07. On it there is a Surface Mount-mount. In order to package its devices, the supplier uses 20-TSSOP. In operation, it should produce a higher temperature than 0°C. Consequently, maximum reliability is achieved by operating at the maximum operating temperature 70°C.
