This electronic part is conveniently packaged in 8-WDFN Exposed Pad, making it easy to ship abroad. To ensure high reliability, a new packaging method Tube is used. Mounted in Surface Mount is this multiplexer. The ratio between the number of multiplexer and demultiplexer circuits is 1:1. Around -40°C~85°C TA is the extended operating temperature. These analog multiplexers are built based on SPST - NO/NC switching circuits. A total of 2 circuits make up this switch device. A voltage of 1.8V~5.5V is required for this switch device, which drains from a single voltage source. It is possible to purchase a 8-TDFN-EP (3x3) package from suppliers.
