Shipping overseas is convenient due to the electrical component's packing in 20-TSSOP (0.173, 4.40mm Width). Advanced packaging method Tape & Reel (TR) is used to provide high reliability. Surface Mount is where this multiplexer is located. Multiplexer and demultiplexer circuits have a number 4:1. The operating temperature is extended to around -40°C~85°C TA. The total number of terminations is 20. This electronic part offers high-quality output due to its 4 channels. A 2.5V voltage supply should turn on and run the electronic component. There are 20 pins injected into the electronic part body. On the other hand, analog switches can be constructed using SP4T switching circuits. A 1 circuit is present in this switch device. This analogue multiplexer requires a voltage of 1.65V~2.75V when it drains from a single voltage supply. It is integrated with a SINGLE-ENDED MULTIPLEXER analog IC.
