Fairchild Semiconductor's FSA3157BL6X sets new benchmarks for analog switch ICs with its patented low-voltage operation down to 1.8V while handling analog signals up to 36V peak. This bidirectional multiplexer/demultiplexer from our premium Interface line offers break-before-make switching action with <20ns transition time. Medical ultrasound systems leverage its precision timing characteristics, while IoT edge devices benefit from its 0.1 A leakage current. The FSA3157BL6X is the preferred choice for: laboratory automation equipment, phased-array radar systems, smart grid sensors, and high-speed data loggers. Its lead-free/GREEN compliance meets global environmental standards.
