A 9 termination consists of terminating transmission lines with a device matching the line's characteristic impedance. 20-TSSOP (0.173, 4.40mm Width) is well known for its low package cost in the electronics industry. Materials are taken from Tape & Reel (TR)'s packaging. On Surface Mount, a PCB can be mounted. It is recommended that the Operating Temperature does not exceed 0°C~70°C. The material qualifies for standard applications as a SCSI, LVD, SE-qualified material. As a precaution, a 4V~5.5V Supply Voltage has been provided. Devices are packaged with 20-TSSOP by the supplier.
