FSAV430BQX

Analog Switches - Special Purpose Overview

The FSAV430BQX is a low voltage, quad single-pole double-throw (SPDT) video switch IC manufactured by Fairchild Semiconductor. It features four independent channels capable of switching analog video signals with a bandwidth of 1.1 GHz. The device operates on a single 3 V supply and offers a maximum on-resistance of 6 Ohms. Key electrical parameters include a typical turn-on time of 7 ns and an off-time of 4 ns. It provides -40 dB typical isolation in the off state. The component is housed in a 16-pin QSOP package and is rated for operation between -40°C and +85°C.

Analog Switches - Special Purpose Feature Summary

• Integrates four independent SPDT switches for multi-channel signal routing
• Supports high-frequency analog video transmission up to 1.1 GHz
• Operates efficiently on a single 3 V power supply
• Provides fast switching speeds with nanosecond-level transition times

Analog Switches - Special Purpose Applications

• Video signal routing in consumer electronics
• Multiplexing audio and video inputs
• Portable multimedia devices requiring low-voltage operation

Analog Switches - Special Purpose Procurement Notes

Verify current availability status as the FSAV430 series may be discontinued or subject to lifecycle changes. Confirm RoHS compliance details through official datasheets before procurement. Ensure the specific suffix matches required packaging options such as cut tape or reel formats.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits that require switching multiple low-voltage video signals simultaneously. Ensure the system operates within the specified 3 V supply range and temperature limits. Verify that the QSOP package dimensions fit the target PCB layout constraints.

Analog Switches - Special Purpose Part Context

This part belongs to the FSAV430 family of video switches from Fairchild Semiconductor, now part of onsemi. The family includes variants like the FSAV430QSCX, which share similar core specifications but may differ in packaging or environmental ratings. These components are designed for compact, low-power video applications.

Analog Switches - Special Purpose Replacement Considerations

Check for direct equivalents within the FSAV430 series, such as the FSAV430QSC. Verify pin compatibility and electrical characteristics against alternative vendors offering quad SPDT video switches with comparable bandwidth and voltage requirements.
