FSA1257AL8X Overview


Due to its 8-UFQFN packaging, the electronic part is convenient for international shipping. This packaging method provides high reliability because it uses advanced packaging techniques. Mounted in Surface Mount is this multiplexer. 1:1 is the ratio of multiplexer to demultiplexer circuits. Around -40°C~85°C TA is the extended operating temperature. The total number of terminations is 8. A electrical component with 2 channels is capable of high-quality output. Turning on and running the electrical part should be easy with a 4.5V voltage supply. A SPST - NC switching circuit is used for these analog switches. Try searching with FSA1257 if you're looking for variants. There is 1.15Ohm internal resistance in this digital multiplexer. For details about the functions of 8 pins, please refer to the datasheets. Multiplexer or Switches is a typical switch device. In a normalsituation, users should not supply the switches with voltage higher than 5.5V. Single supply type digital switch with a low cost. 2.7V is the lowest voltage that should be fed to the electronic electronic part. A voltage of 2.7V~5.5V is required to drain this analog switch from a single voltage supply. The analogue multiplexer may be damaged if voltage is greater than 500nA. In this switch multiplexer, there are SEPARATE OUTPUT outputs available.
