An example of a 9 termination would be one in which the characteristic impedance of the transmission line is matched to the device terminating the transmission line. 20-TSSOP (0.173, 4.40mm Width) is well known for its low package cost in the electronics industry. Tape & Reel (TR)'s materials are followed in the packaging. The PCB is mounted using Surface Mount. 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. The 4V~5.5V Supply Voltage ensures normal operation. Suppliers use 20-TSSOP as a device package.
