FSA2269TSUMX

Analog Switches - Special Purpose Overview

The FSA2269TSUMX is a low-voltage dual single-pole double-throw (SPDT) analog switch manufactured by onsemi, formerly Fairchild Semiconductor. It operates within a supply voltage range of 1.65 V to 4.5 V and features a maximum on-resistance of 300 mOhms. The device supports a continuous DC switch current of 350 mA with a maximum power supply current of 100 nA. Key timing parameters include a maximum turn-on time of 3.5 µs and a maximum turn-off time of 45 ns. It is housed in a UMLP-10 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distribution channels due to the manufacturer's acquisition history. Confirm RoHS compliance status as specified in the official datasheet. Check for end-of-life notices or obsolescence warnings prior to procurement planning. Ensure storage conditions adhere to moisture sensitivity level requirements for the UMLP-10 package.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring dual signal paths with low voltage operation between 1.65 V and 4.5 V. Consider the 300 mOhm on-resistance limit for signal integrity requirements. Evaluate the UMLP-10 package dimensions against available PCB real estate. Verify that the 350 mA continuous current rating meets the load requirements of the switched signals.

Analog Switches - Special Purpose Part Context

This part belongs to the FSA2269TS family of analog switches. It represents a transition from Fairchild Semiconductor to onsemi following corporate restructuring. The component is designed for space-constrained portable electronics where low power consumption and small footprint are critical design constraints.

Analog Switches - Special Purpose Replacement Considerations

Check for direct pin-compatible substitutes within the same product family. Verify electrical specifications match if considering cross-manufacturer alternatives. Confirm package compatibility for UMLP-10 footprints.
