FSA636UCX

Analog Switches - Special Purpose Overview

The FSA636UCX is a dual SPST analog switch manufactured by onsemi, housed in a compact SC-70-6 surface-mount package. It features low ON resistance and minimal charge injection for signal integrity. The device operates with a single supply voltage range of 1.65V to 5.5V, ensuring compatibility with various digital logic families. Key electrical specifications include an ON resistance of typically 2.5 ohms at 3.3V and a bandwidth exceeding 800MHz. Leakage current is maintained below 1nA at room temperature, supporting high-impedance states when disabled.

Analog Switches - Special Purpose Feature Summary

• Dual single-pole single-throw configuration for independent channel control
• Low ON resistance ensures minimal signal attenuation across the passband
• Ultra-low leakage current maintains signal isolation when switched off
• Compatible with low-voltage digital interfaces for seamless system integration

Analog Switches - Special Purpose Applications

• Portable multimedia devices requiring signal routing
• LCD panel biasing and data line switching
• Audio signal path management in consumer electronics
• USB hub port selection and multiplexing circuits

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity and packaging variant. Confirm that the device grade meets the environmental standards for the intended application. Cross-reference the datasheet revision date to ensure all electrical characteristics align with current manufacturing specifications. Ensure proper ESD handling procedures are followed during assembly due to the sensitive input structures.

Analog Switches - Special Purpose Selection Notes

Choose this component when space constraints require a small footprint alongside low power consumption requirements. Evaluate the ON resistance tolerance against the maximum allowable signal loss in the application. Consider the operating voltage range to ensure compatibility with the system's power rails. Assess the need for dual channels versus single-channel alternatives based on circuit complexity.

Analog Switches - Special Purpose Part Context

This part belongs to onsemi's family of low-power analog switches designed for portable applications. It complements other devices in the series offering similar functionality with varying pin counts or performance trade-offs. The SC-70-6 package provides a balance between thermal performance and board space efficiency compared to larger packages.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes may include parts from the same manufacturer with identical pinouts and electrical characteristics. Verify functional equivalence regarding ON resistance and leakage current before substitution. Check for any differences in recommended operating conditions or thermal dissipation requirements.
