Termination with a 9 device, which matches the transmission line's characteristic impedance, is considered a 9 termination. In the electronic industry, the 20-TSSOP (0.173, 4.40mm Width) has a reputation for being economical. Packaging follows Tape & Reel (TR)'s material specifications. The PCB is mounted using Surface Mount. It should not exceed 0°C~70°C°C when operating. It is a SCSI, LVD, SE-qualified material for standard applications. As a precaution, a 4V~5.5V Supply Voltage has been provided. Devices are packaged with 20-TSSOP by the supplier.
