FSA2259UMX

Analog Switches, Multiplexers, Demultiplexers Overview

The FSA2259UMX is a dual Single Pole Double Throw (SPDT) analog switch manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 4.4 V and features a maximum on-resistance of 500 mOhms. The device supports a DC switch current of 350 mA with a maximum power supply current of 100 nA. Switching performance includes a maximum turn-on time of 55 ns and a maximum turn-off time of 30 ns. It is housed in a UMLP-10 package and functions reliably across an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the component matches the required UMLP-10 footprint dimensions for PCB layout compatibility before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high bandwidth are required for portable consumer electronics. Verify that the 1.65 V minimum supply voltage aligns with the system's power rails. Ensure the UMLP-10 package size fits within the available board space constraints for mobile devices.

Analog Switches, Multiplexers, Demultiplexers Part Context

The FSA2259 belongs to onsemi’s portfolio of multiplexers and crosspoint switches designed for high-speed signal routing. These devices typically offer low jitter and ESD protection suitable for mobile handsets and media tablets. The series meets JEDEC latchup test specifications for robust industrial and consumer applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consult official substitution guides for verified equivalents. Generic SPDT switches may not match the specific 0.8Ω typical on-resistance or the 50MHz bandwidth characteristics required for this application.
