It runs on a single 2.3V to 3.6V supply. Four independent 2:1 mux/demux channels mean you can swap between two data sources — say, a primary and backup SPI flash — or share one ADC input across two analog front-ends. The single-supply rail and industrial temperature range (-40°C to 85°C) make it a fit for outdoor telecom cabinets, factory-floor PLC racks, and any board that lives in a ventilated but unheated enclosure. ## Package and footprint The 16-SOIC (0.154\", 3.90mm width) body is a standard surface-mount footprint. The Tape & Reel and Cut Tape options cover both prototype and production runs. ## Lifecycle and compliance ROHS3 compliance is confirmed. It clears the EU RoHS directive without an exemption claim.","metaTitle":"QS3VH257S1G8 Bus Switch, 4 x 2:1, 16-SOIC, Active","metaDescription":"QS3VH257S1G8 is an active bus switch from the 3VH series, 4 x 2:1 circuit, 2.3V-3.6V supply, industrial temp -40 to 85°C.
