Overview
The NX3L4684GM,132 is a dual low-ohmic single-pole double-throw analog switch manufactured by NXP USA Inc. It operates on a single supply voltage ranging from 1.4 V to 4.3 V and is housed in an XQFN10 package (SOT1049-3). The device features two independent switches with digital select inputs, supporting bidirectional signal transmission up to the supply voltage level. Key electrical parameters include a typical ON resistance of 0.25 Ω for the Y0 port at 2.7 V or higher, and 0.5 Ω for the Y1 port at 2.7 V or higher. The component supports continuous current handling of 350 mA under a 3.3 V supply.
Feature Summary
- Very low ON resistance ensures minimal signal attenuation and distortion across various supply voltages.
- Capable of switching signals up to VCC using a lower 1.8 V control logic without requiring level translation.
- Provides high noise immunity and robust ESD protection exceeding specified industry standards.
- Features break-before-make switching action to prevent short circuits during channel transitions.
Applications
- Cell phones
- Personal Digital Assistants (PDA)
- Portable media players
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the package type and temperature range. Confirm that the required ambient operating conditions align with the -40 °C to +125 °C specification. Ensure design compatibility with the XQFN10 footprint dimensions and thermal requirements before finalizing procurement.
Selection Notes
Select this component when low signal distortion and high current handling are critical for portable applications. Verify that the control logic voltage levels are compatible with the device's input thresholds. Consider the thermal dissipation characteristics if operating near maximum current limits. Ensure the application does not require operation beyond the specified absolute maximum ratings.
Part Context
This part belongs to the NX3L series of low-power analog switches designed for mobile and portable electronics. It shares functional similarities with other dual SPDT switches but is distinguished by its ultra-low ON resistance profile. The series targets applications requiring efficient signal routing in space-constrained environments with strict power consumption constraints.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's official replacement guide or contact authorized distributors for verified cross-reference information.
