FSA2567UMX-F135

Analog Switches - Special Purpose Overview

The FSA2567UMX-F135 is a low-power, dual SIM card analog switch manufactured by onsemi. It functions as a bi-directional, dual double-pole, double-throw (4PDT) switch designed for multiplexing WLAN-SIM data and control signals while dedicating one channel as a supply-source switch. The device operates within a VCC range of 1.65 V to 4.3 V and features a typical on capacitance of 10 pF for the data path and an on resistance of 6 Ω for the data path and 0.4 Ω for the supply path. It supports a wide -3 dB bandwidth exceeding 160 MHz and maintains a maximum quiescent current consumption of 1 μA.

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'F135' against official documentation to confirm reel packaging specifications. Ensure the component matches the updated ON Semiconductor nomenclature standards following the Fairchild integration, replacing any legacy underscore characters with dashes in ordering systems.

Analog Switches - Special Purpose Selection Notes

Select this component when designing dual SIM interfaces requiring low signal distortion and high isolation. The device is appropriate for applications needing direct baseband processor interfacing due to its low control leakage. Validate that the operating voltage range aligns with the system's VCC requirements and that the MLP or UMLP package fits the board layout constraints.

Analog Switches - Special Purpose Part Context

This part belongs to the FSA2567 series of low-power analog switches originally developed by Fairchild Semiconductor before its acquisition by ON Semiconductor. The series is engineered specifically for portable electronics managing multiple SIM modules. The FSA2567UMX variant utilizes a 16-lead Ultrathin Molded Leadless Package (UMLP).

Analog Switches - Special Purpose Replacement Considerations

Check the ON Semiconductor website for updated part numbers reflecting the transition from Fairchild naming conventions. Verify pin compatibility and electrical parameters if substituting with other dual-channel analog switches from the same manufacturer family.
