FSAL200QSCX

Analog Switches, Multiplexers, Demultiplexers Overview

The FSAL200QSCX is a wideband quad 2:1 analog multiplexer/demultiplexer switch manufactured by onsemi. It features four independent single-pole double-throw (SPDT) switches within a single package, providing signal routing flexibility for audio and video applications. The device operates with a supply voltage range of 5V to 55V and supports an analog signal range from VCC to 0V. Key electrical characteristics include a maximum on-resistance of 22Ω at 30V to 36V supply and 12Ω at 5V to 55V supply under specified current conditions. The component is designed for an ambient operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific manufacturer source, as Rochester Electronics has historically distributed this part number. Confirm that the QSOP-16 package matches the required footprint and pin configuration for the design. Ensure the component meets the necessary automotive or industrial qualification standards if the application requires it, as original Fairchild/ON Semiconductor documentation should be consulted for full compliance details.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when multiple independent analog signal paths require switching within a limited board space. The wide supply voltage capability allows compatibility with various system power rails. Consider the on-resistance flatness and leakage current specifications to ensure signal fidelity is maintained across the entire operating temperature range and voltage swing.

Analog Switches, Multiplexers, Demultiplexers Part Context

The FSAL200 series belongs to the family of wideband analog switches originally developed by Fairchild Semiconductor and later continued by ON Semiconductor. These devices are engineered for high-performance analog signal routing, offering low distortion and fast switching times. The QSCX suffix typically denotes a specific tape-and-reel packaging variant suitable for automated surface-mount assembly processes.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements may include other quad SPDT analog switches from ON Semiconductor or legacy Fairchild inventory. Verify pin-to-pin compatibility and electrical parameter equivalence, particularly regarding on-resistance and supply voltage limits, before substituting.
