This electronic part is conveniently packaged in 10-TFSOP, 10-MSOP (0.118, 3.00mm Width), making it easy to ship abroad. Advanced packaging method Tape & Reel (TR) is used to provide high reliability. A switch device like this is mounted in Surface Mount. 2:1 is the ratio between multiplexers and demultiplexers. Operating temperature extended to -40°C~125°C TA. There are 10 terminations totally. The electronic part provides high-quality output because it has 1 channels. In the case of a voltage supply of 2.7V volts, the electrical part can be powered up and run. Electronic part bodies are injected with 10 pins. Circuits based on SPDT switching are used to construct these analog switch ics. Circuits number 2 make up this analogue multiplexer. An analogue multiplexer drains from a single voltage supply at 1.65V~3.6V.
