FSA2567UMX_F113

Analog Switches - Special Purpose Overview

The FSA2567UMX_F113 is a low-power, dual double-pole, double-throw (DPDT) analog switch designed for dual SIM card multiplexing applications. It integrates four SPDT switches and one dedicated supply-source switch within a single package. The device operates over a wide VCC range of 1.65V to 4.3V with a maximum quiescent current of 1μA. Key electrical parameters include a typical on-resistance of 6Ω for data paths and 0.4Ω for the supply path, alongside a -3dB bandwidth exceeding 160MHz. It features low on-capacitance of 10pF typical and supports 3kV ESD ratings.

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance and material declarations against current regulatory requirements. Validate packaging integrity upon receipt. Cross-reference ordering suffixes with official documentation to ensure correct pinout and functionality. Maintain records of procurement sources for quality assurance audits.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring dual SIM multiplexing with low power constraints. Ensure the operating voltage range aligns with the system's 1.65V to 4.3V specification. Consider the 16-lead MLP or UMLP package dimensions for PCB layout compatibility. Evaluate thermal performance if high current flows through the supply source switch. Verify that the 160MHz bandwidth meets the signal frequency requirements of the application.

Analog Switches - Special Purpose Part Context

The FSA2567 series belongs to onsemi's portfolio of low-power analog switches targeting mobile communication devices. It replaces earlier Fairchild Semiconductor designs under the same functional specifications. The part is commonly found in legacy mobile phone designs and embedded systems requiring reliable SIM card switching. Its integration of a supply source switch simplifies board design by reducing external component count.

Analog Switches - Special Purpose Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The FSA2567MPX shares identical electrical characteristics but differs in package type. Designers should verify pin-to-pin compatibility and thermal dissipation capabilities before substituting packages. Consult official obsolescence notices for recommended alternative components.
