FSAV331QSC

Analog Switches - Special Purpose Overview

The FSAV331QSC is a video switch integrated circuit manufactured by onsemi, formerly Fairchild Semiconductor. It features a dual-channel configuration with two independent 4:1 multiplexers housed in a QSOP-16 surface-mount package. The device operates on a single 5 V supply and supports a bandwidth of 300 MHz. Key electrical parameters include a maximum on-resistance of 10 Ohms, typical off-isolation of -56 dB, and propagation delay of 1 ns. Switching times are specified at a maximum of 5.3 ns for turn-on and 5.8 ns for turn-off. The component functions within an operating temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Dual-channel architecture providing two separate 4:1 signal selection paths
• High-speed switching capability suitable for wideband video applications
• Low on-resistance for minimal signal attenuation during conduction

Analog Switches - Special Purpose Applications

• Video signal routing and distribution systems
• Multiviewer displays requiring multiple input selection
• Test and measurement equipment signal path switching

Analog Switches - Special Purpose Procurement Notes

Verify the manufacturer status carefully as this part is associated with onsemi following the acquisition of Fairchild Semiconductor. Confirm RoHS compliance details as listed specifications may vary by production lot or revision. Ensure the QSOP-16 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Analog Switches - Special Purpose Selection Notes

Select this component when a dual 4:1 video switch topology is required. Compare the 300 MHz bandwidth against specific video resolution needs. Evaluate the 10 Ohm on-resistance limit for signal integrity constraints. Verify that the 5 V single-supply operation aligns with the system power design.

Analog Switches - Special Purpose Part Context

This component belongs to the FSAV series of video switches. It serves as a legacy part from the Fairchild Semiconductor portfolio, now managed under onsemi. The device provides a compact solution for managing multiple video inputs in space-constrained electronic designs.

Analog Switches - Special Purpose Replacement Considerations

Check for direct pin-compatible replacements within the current onsemi video switch portfolio. Verify if newer revisions offer updated packaging or compliance certifications while maintaining identical electrical characteristics.
