FSAV332QSC

Analog Switches - Special Purpose Overview

The FSAV332QSC is a quad video switch integrated circuit manufactured by onsemi, formerly Fairchild Semiconductor. It features four independent single-pole single-throw (SPST) switches housed in a 16-pin QSOP package. The device operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range from -40°C to +85°C. Key electrical specifications include a maximum on-resistance of 10 ohms and a -3dB bandwidth of 368MHz. This component is designed for high-speed video signal routing applications.

Analog Switches - Special Purpose Feature Summary

• Provides four individually enabled SPST analog switches for flexible signal routing
• Optimized for wideband video signal transmission with high bandwidth capability
• Supports standard 5V single-supply operation for compatibility with common logic levels

Analog Switches - Special Purpose Applications

• Video signal switching and routing systems
• Multimedia equipment requiring analog signal path selection
• Test and measurement instrumentation for signal distribution

Analog Switches - Special Purpose Procurement Notes

Verify the manufacturer status carefully as this part is listed as obsolete or discontinued by major distributors. Confirm if the source is an authorized distributor or a secondary market supplier like Rochester Electronics. Ensure the specific QSOP package variant matches the design requirements before procurement due to end-of-life status.

Analog Switches - Special Purpose Selection Notes

Select this component only if the 16-pin QSOP footprint is mandatory for the PCB layout. Consider the 368MHz bandwidth limit when evaluating signal integrity requirements. Verify that the 10-ohm on-resistance meets the impedance matching needs of the specific video application. Check for available pin-compatible alternatives if long-term supply stability is required.

Analog Switches - Special Purpose Part Context

This component belongs to the FSAV33 series of video switches. It shares functional similarities with other variants such as the FSAV332MTCX but differs in packaging. The transition from Fairchild Semiconductor to onsemi affects part numbering and documentation sources. Designers should reference the specific datasheet for the QSC suffix to ensure accurate pinout and electrical characteristics.

Analog Switches - Special Purpose Replacement Considerations

Public confirmed substitute part numbers include FSAV332MTCX and FSAV332QSC_NL. Verify pin compatibility and electrical parameters before substitution. Note that some alternatives may have different packaging options or updated manufacturing origins.
