Shipping overseas is convenient due to the electrical component's packing in 20-TSSOP (0.173, 4.40mm Width). To ensure high reliability, a new packaging method Tape & Reel (TR) is used. In Surface Mount, this analog switch is mounted. There is 4:1 ratio between the number of multiplexers and demultiplexers. An extended operating temperature of -40°C~85°C TA degrees Celsius. There are 20 terminations totally. This electronic part offers high-quality output due to its 4 channels. Powered by a 2.5V voltage supply, the electrical part should be switched on and run. As part of its design, the 20 series is equipped with this electronic component. On the other hand, analog switches can be constructed using SP4T switching circuits. 1 circuits are used in this analogue multiplexer. A voltage of 1.65V~2.75V is required for this switch device, which drains from a single voltage source. There is an analog IC SINGLE-ENDED MULTIPLEXER integrated with this board.
