FSA2269L10X

Analog Switches - Special Purpose Overview

The FSA2269L10X is a low-voltage dual single-pole double-throw (SPDT) analog switch manufactured by Fairchild Semiconductor. It features a maximum on-resistance of 300 mOhms and operates within a supply voltage range of 1.65 V to 4.5 V. The device supports a continuous DC switch current of 350 mA with a maximum power consumption of 100 nA. Key timing parameters include a maximum turn-on time of 105 ns and a maximum turn-off time of 100 ns. It functions reliably across an operating temperature range from -40 °C to +85 °C and is housed in a UMLP-10 surface-mount package.

Analog Switches - Special Purpose Procurement Notes

Verify the specific manufacturer designation, as Fairchild Semiconductor's semiconductor division was acquired by onsemi. Confirm that the component is sourced from authorized distributors to ensure authenticity. Check for End-of-Life status or obsolescence notices, as availability may be limited. Ensure the UMLP-10 package type matches the PCB footprint requirements.

Analog Switches - Special Purpose Selection Notes

Select this component when a dual-channel analog switch with low on-resistance is required for low-voltage applications. The 1.65 V minimum supply voltage makes it suitable for battery-powered systems. Verify that the 105 ns switching speed meets the system timing constraints. Ensure the thermal management plan accommodates the specified operating temperature range.

Analog Switches - Special Purpose Part Context

This part belongs to the FSA226x series of low-voltage analog switches. It shares functional similarities with the FSA2268 but offers different packaging and potentially distinct electrical characteristics optimized for specific signal integrity needs. The L10 suffix typically denotes the specific tape-and-reel packaging format.

Analog Switches - Special Purpose Replacement Considerations

The FSA2268L10X is a related component within the same family. Verify pin compatibility and electrical specifications before substitution. Other dual SPDT switches with similar voltage ranges may serve as alternatives if pin-to-pin compatibility is confirmed.
