DS2120E OverviewIt is possible to terminate a transmission line with a device matching the impedance of the line, which is known as 9 termination. A well-known feature of the 28-TSSOP (0.173, 4.40mm Width) is its low packaging cost. Materials used for packaging are the same as those used by Tube. The PCB is mounted using Surface Mount. It is recommended that the Operating Temperature does not exceed 0°C~70°C. Standard applications can be carried out with this SCSI, LVD, SE-qualified material. Normal operation is ensured by a 2.7V~5.5V Supply Voltage. There are specific uses for the 28 pins. A 9 signal line is one that is exclusively used for transmitting signals or intelligence, or for public or private communication.
