The electronic part can be shipped overseas conveniently because it is packaged in 16-SOIC (0.154, 3.90mm Width). The advanced packaging method Tape & Reel (TR) provides high reliability. The multiplexer is located in Surface Mount. There is 4:1 ratio between the number of multiplexers and demultiplexers. Increasing operating temperature to around -40°C~125°C TA. In total, 16 terminations have occurred. The electronic part provides high-quality output because it has 4 channels. When the electronic component is given a voltage of 5V, it should be turned on and run. These analog multiplexers are built based on SP4T switching circuits. Circuits number 2 make up this analogue multiplexer. An switch multiplexer with 78Ohm internal resistance has a value of 78Ohm. To find out what the 16 pins do, please refer to the datasheets. There is an integrated analog IC DIFFERENTIAL MULTIPLEXER in the module.
