The electronic component is convenient to ship overseas because it is packed in a 20-TSSOP (0.173, 4.40mm Width). The advanced packaging method Tube provides high reliability. It is mounted in the position Surface Mount. 4:1 is the ratio between multiplexers and demultiplexers. The operating temperature is extended to around -40°C~85°C TA. The total number of terminations is 20. As a result of its 4 channels, this electronic component provides high-quality output. An 2.5V voltage supply should allow the electrical part to be turned on and run. A total of 20 pins are injected into the body of the electronic part. Based on SP4T switching circuits, these analog multiplexers work. The multiplexer consists of 1 circuits. Using only a single voltage supply, this analog switch requires 1.65V~2.75V voltage. With a SINGLE-ENDED MULTIPLEXER analog IC integrated into the board.
