DS21S07AE 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. Tube'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 DS21S07A. There are a number of 20 pins included for specific applications. In terms of 9 signal lines, these are lines devoted exclusively to the transmission of signals or intelligence, either public or private. For high efficiency, it is recommended that the supply voltage is maintained at 5V. Power Supplies are needed to operate 5V Power Supplies.
