Overview
The FSA2467MPX is a dual double-pole double-throw (DPDT) analog switch manufactured by onsemi, formerly Fairchild Semiconductor. It operates on a single supply voltage ranging from 1.65 V to 4.3 V. The device features a maximum on-resistance of 400 mOhms and supports a DC switch current of 350 mA. Switching performance includes a maximum turn-on time of 50 ns and a maximum turn-off time of 32 ns. It is housed in a 16-lead MLP package measuring 3x3 mm with a height of 0.75 mm. The component functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual DPDT configuration providing two independent switching channels in a compact footprint.
- Low on-resistance characteristic ensuring minimal signal attenuation across the passband.
- Ultra-low power consumption suitable for battery-operated portable electronics.
- High bandwidth capability supporting high-speed data transmission applications.
Applications
- Portable multimedia devices requiring signal routing between multiple sources.
- Mobile phones and smartphones for antenna and audio path switching.
- Digital still cameras and camcorders for sensor interface management.
- Personal digital assistants and handheld computing devices.
Procurement Notes
Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm RoHS compliance documentation matches specific manufacturing dates. Check for alternative sourcing options as original inventory may be limited. Validate package markings against official datasheet specifications to prevent counterfeit substitution.
Selection Notes
Select this component when dual independent switching paths are required in space-constrained designs. Ensure supply voltage requirements align with the 1.65 V to 4.3 V operational range. Consider the 16-lead MLP package dimensions for PCB layout constraints. Evaluate thermal performance needs against the specified operating temperature limits.
Part Context
This part belongs to the FSA2467 series of low-power analog switches designed for portable applications. It represents a transition from Fairchild Semiconductor to onsemi following corporate acquisition. The device replaces older discrete switching solutions with integrated IC functionality. It shares architectural similarities with other members of the FSA family but offers specific channel configurations.
Replacement Considerations
Check for pin-compatible alternatives within the same manufacturer's portfolio. Verify electrical parameters such as on-resistance and switching times match original design requirements. Confirm package dimensions remain identical for direct board replacement. Review updated datasheets for any functional changes introduced after the acquisition.
