Packed in 8-TSSOP, 8-MSOP (0.118, 3.00mm Width), the electronic component is convenient for shipping overseas. The advanced packaging method Tube provides high reliability. A switch device like this is mounted in Surface Mount. 2:1 is the number of circuits in the multiplexer and demultiplexer. Increasing operating temperature to around -40°C~85°C TA. In total, there have been 8 terminations. A 1 channel electronic part produces high-quality output. It is safe to turn on and run the electronic component with a 3V voltage supply. There is an electrical component included in the 8 series. Unlike digital switches, these  are based on SPDT switching circuits. This multiplexer is composed of 1 circuits. A voltage of 1.8V~5.5V is required for this switch device, which drains from a single voltage source. You shouldn't miss the additional features of the electrical component, such as: CAN ALSO OPERATE WITH 5V SUPPLY.
