FSAV450QSCX

Analog Switches - Special Purpose Overview

The FSAV450QSCX is an audio/video switch manufactured by Fairchild Semiconductor, distributed by Rochester Electronics. It features four functions and two channels within a 16-pin QSOP package (MO-137AB). The device operates with a maximum on-resistance of 6Ω and provides a nominal off-isolation of 50 dB. It supports a functional temperature range from -40°C to 85°C. The component is lead-free and RoHS compliant, utilizing a plastic dual small-outline package with a length of 5 mm.

Analog Switches - Special Purpose Feature Summary

• Provides switching capability for four distinct functions across two channels
• Ensures signal integrity through low on-resistance characteristics
• Maintains channel separation via high off-isolation performance

Analog Switches - Special Purpose Applications

• LCD display video signal routing
• Plasma display panel input selection
• General-purpose analog video switching

Analog Switches - Special Purpose Procurement Notes

Verify the manufacturer designation as Rochester Electronics rather than original Fairchild production when sourcing. Confirm the specific package variant matches the MO-137AB QSOP-16 specification. Ensure compliance with lead-free and RoHS standards is documented in the certificate of conformity prior to integration into final assemblies.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring quad-channel switching functionality within a compact surface-mount footprint. Evaluate the 6Ω on-resistance against the load requirements to ensure acceptable signal attenuation. Verify that the 800MHz bandwidth aligns with the highest frequency components present in the target video or audio signals.

Analog Switches - Special Purpose Part Context

This part belongs to the FSAV series of high-bandwidth video switches originally developed by Fairchild Semiconductor. The series includes variants such as the FSAV430 and FSAV330, which offer different bandwidths and channel configurations. The FSAV450 specifically targets LCD and plasma display applications requiring transparent switching operations.

Analog Switches - Special Purpose Replacement Considerations

The FSAV450QSC serves as a direct pin-compatible alternative without the 'X' suffix. Other family members like the FSAV430 offer higher bandwidth but may require voltage level adjustments.
