This electronic part is conveniently packaged in 20-WFQFN Exposed Pad, CSP, making it easy to ship abroad. This high-reliability packaging method uses advanced packaging methods Cut Tape (CT). A switch device like this is mounted in Surface Mount. 2:1 is the ratio of multiplexer to demultiplexer circuits. An extended operating temperature of -40°C~125°C TA degrees Celsius. In total, there have been 20 terminations. A 1 channel electronic part produces high-quality output. A 15V voltage supply should turn on and run the electronic component. As part of its design, the 20 series is equipped with this electronic component. Unlike digital switches, these are based on SPDT switching circuits. 3 circuits are used in this analogue multiplexer. Try searching for ADG5243 variants of the analog switch ic. To find out what the 20 pins do, please refer to the datasheets.
