Overview
The NX3L4357GM,132 is a low-ohmic single-pole triple-throw analog switch manufactured by NXP USA Inc. It operates on a supply voltage range of 1.4 V to 4.3 V and features Schmitt trigger inputs for noise immunity. The device supports bidirectional signal transmission up to VCC with an ON resistance as low as 0.5 Ω. It includes broadcast mode functionality and break-before-make switching. Packaged in a 10-terminal XQFN10 (SOT1049-3) surface-mount format measuring 2 x 1.55 mm, it is rated for ambient temperatures from -40 °C to +125 °C.
Feature Summary
- Broadcast mode capability allows simultaneous connection of the common port to all three independent ports when select inputs are high.
- Low threshold digital inputs enable direct control by 1.8 V logic levels while switching signals up to 4.3 V without level translation.
- Break-before-make switching design prevents short circuits during channel transitions.
- High electrostatic discharge protection meets rigorous standards including Human Body Model Class 3A exceeding 7500 V.
Applications
- Cell phones
- Personal Digital Assistants (PDA)
- Portable media players
Procurement Notes
Verify component authenticity through authorized distribution channels or direct manufacturer verification. Confirm the specific ordering suffix matches project requirements. Check current product status as availability may vary. Ensure storage and handling procedures comply with moisture sensitivity level specifications to prevent package damage prior to soldering.
Selection Notes
Select this component for applications requiring low signal attenuation and minimal distortion in portable electronics. Verify that the operating voltage range aligns with the system power rails. Consider the thermal derating characteristics if operating near maximum temperature limits. Evaluate the package dimensions against available PCB real estate constraints.
Part Context
This part belongs to the NX3 series of analog switches designed for low-power consumer electronics. It serves as a multiplexer or demultiplexer solution within NXP's interface IC portfolio. The device integrates CMOS technology to minimize static power consumption while maintaining high current handling capabilities for signal routing tasks.
Replacement Considerations
The NX3L4357GM,115 is a documented variant of the same functional device. Verify pinout compatibility and electrical specifications before substitution. Ensure the alternative package version meets mechanical footprint requirements. Confirm environmental compliance status matches project regulations.
