FSA223MUX

Analog Switches - Special Purpose Overview

The FSA223MUX is a dual analog switch manufactured by Fairchild Semiconductor, designed for signal routing applications. It features two independent single-pole single-throw (SPST) switches within a compact package. The device supports low on-resistance and high bandwidth, making it suitable for audio and video signal paths. It operates with a wide supply voltage range and offers low power consumption. The component is housed in a small outline package to facilitate space-constrained designs.

Analog Switches - Special Purpose Feature Summary

• Dual SPST configuration for independent signal path control
• Low on-resistance for minimal signal attenuation
• High bandwidth capability for fast signal switching
• Wide operating supply voltage range

Analog Switches - Special Purpose Applications

• Audio signal routing and switching
• Video signal multiplexing
• Data acquisition systems
• Communication equipment signal selection

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix codes against the manufacturer's current datasheet to ensure correct pinout and packaging options. Confirm RoHS compliance status as manufacturing processes may update over time. Check for any obsolescence notices or lifecycle changes from Fairchild or its successor entities before finalizing procurement plans.

Analog Switches - Special Purpose Selection Notes

Select this component when dual isolated analog switching is required in a small footprint. Ensure the signal amplitude stays within the absolute maximum ratings to prevent damage. Consider the on-resistance variation across temperature if precision signal integrity is critical for the application design.

Analog Switches - Special Purpose Part Context

This part belongs to Fairchild's family of analog switches, which are widely used in consumer electronics and industrial controls. The series provides reliable performance for general-purpose signal routing tasks. Fairchild Semiconductor has undergone corporate restructuring, so verify current availability through authorized distributors or the parent company's official channels.

Analog Switches - Special Purpose Replacement Considerations

Check for direct pin-to-pin replacements such as the FSAL223MUX or similar dual SPST switches from other manufacturers like TI or ADI. Verify that the replacement matches the voltage range, on-resistance, and package dimensions. Always consult the latest datasheets for electrical parameter compatibility.
