The electronic component is convenient to ship overseas because it is packed in a 20-TSSOP (0.173, 4.40mm Width). In order to provide high reliability, an advanced packaging method Tape & Reel (TR) is used. It is mounted in the position Surface Mount. There is 4:1 ratio between the number of multiplexers and demultiplexers. An extended operating temperature of -40°C~85°C TA degrees Celsius. Totally, there are 20 terminations. The electronic part provides high-quality output because it has 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. A SP4T switching circuit is used to build these analog multiplexers. This multiplexer is composed of 1 circuits. Try searching for ADG904 variants of the analog switch ic. Please refer to the datasheets for 20 pins functions. A voltage higher than 2.75V should not normally be supplied to the switches. A cost-effective Single supply type analogue multiplexer. The lowest voltage fed to the electronic component should be 1.65V. The voltage required by this switch device is 1.65V~2.75V, draining from a single voltage supply. Operating voltages of 2.75V are compatible with the electrical part. Operating the 4 inputs requires 4 inputs. There are 2.5 GHz bandwidths for data transfer.
