FSAV450QSC

Analog Switches - Special Purpose Overview

The FSAV450QSC is an 800MHz quad SPDT video switch manufactured by Fairchild Semiconductor. It integrates four independent 2:1 analog switches within a single package, designed for high-frequency signal routing in audio and video applications. The device operates with a low supply voltage range of 2.7V to 5.5V, ensuring compatibility with standard logic levels. Key electrical parameters include a maximum on-resistance (Ron) of 6Ω and a typical off-isolation of 50dB at DC. The component supports a wide operating temperature range from -40°C to +85°C and is housed in a 16-pin SSOP package.

Analog Switches - Special Purpose Feature Summary

• Integrates four independent single-pole double-throw (SPDT) channels for compact signal routing
• Supports high-bandwidth video signals up to 800MHz with minimal distortion
• Operates efficiently with low voltage supplies ranging from 2.7V to 5.5V

Analog Switches - Special Purpose Applications

• LCD and Plasma display panel signal switching
• Video distribution systems requiring multi-channel routing
• Audio/Video equipment input selection circuits

Analog Switches - Special Purpose Part Context

The FSAV450QSC belongs to the FSAV series of high-speed analog switches developed by Fairchild Semiconductor. This series is engineered for consumer electronics requiring reliable video signal integrity. The 'Q' suffix typically denotes automotive or qualified grade variants, while 'SC' indicates the specific SSOP-16 package configuration used in space-constrained designs.

Analog Switches - Special Purpose Replacement Considerations

Direct replacements include the FSAV430 for higher bandwidth requirements up to 1.1GHz, or the FSAV330 for lower-cost dual-channel applications. Verify pinout compatibility and voltage specifications when substituting with other members of the FSAV family.
