Due to its 12-UFQFN packaging, the electronic part is convenient for international shipping. High reliability is achieved by using advanced packaging method Tape & Reel (TR). Mounted in Surface Mount is this multiplexer. Multiplexers and demultiplexers have the same number of circuits 3:1. Operation at a temperature around -40°C~85°C TA. A total of 12 terminations have been recorded. The electronic part delivers high-quality output through its 3 channels. Turning on and running the electrical part should be easy with a 3V voltage supply. Electronic part bodies are injected with 12 pins. SP3T switching circuits are used in these analog switch ics. A 2 circuit is present in this switch device. ISL54233 can be used to search for analog multiplexer variants. The voltage required by this switch device is 2.7V~4.6V, draining from a single voltage supply. There is an analog IC DIFFERENTIAL MULTIPLEXER integrated with this board.
