The electronic part can be shipped overseas conveniently because it is packaged in 16-SOIC (0.154, 3.90mm Width). In order to provide high reliability, an advanced packaging method Tape & Reel (TR) is used. The multiplexer is located in Surface Mount. The ratio between the number of multiplexer and demultiplexer circuits is 1:1. The operating temperature is extended to around -40°C~125°C TA. Totally, there are 16 terminations. A high-quality output is provided by the electrical component's 4 channels. Based on SPST - NC switching circuits, these analog multiplexers work. There are 4 circuits in this switch device.
