The electronic component is convenient to ship overseas because it is packed in a 20-TSSOP (0.173, 4.40mm Width). To ensure high reliability, a new packaging method Tape & Reel (TR) is used. Multiplexers like this are mounted in the Surface Mount position. 4:1 is the ratio between multiplexers and demultiplexers. Increasing operating temperature to around -40°C~85°C TA. In total, there are 20 terminations. The electronic part provides high-quality output because it has 4 channels. When the electronic component is given a voltage of 2.5V, it should be turned on and run. As part of the design of the 20 series, this electronic part has been incorporated into the system. On the other hand, analog switches can be constructed using SP4T switching circuits. The circuits in this analogue multiplexer number 1. The voltage required by this switch device is 1.65V~2.75V, draining from a single voltage supply. This product is integrated with an analog integrated circuit (IC) of type SINGLE-ENDED MULTIPLEXER.
