Overview
The NX3L4357GM,115 is a low-ohmic single-pole triple-throw analog switch manufactured by NXP Semiconductors. It operates on a single supply voltage ranging from 1.4 V to 4.3 V and utilizes an XQFN10 package (SOT1049-3). The device features two digital select inputs (S0, S1), one active-low enable input (E), three independent I/Os (Y0, Y1, Y2), and a common I/O (Z). It supports broadcast mode when both select inputs are high. Typical ON resistance varies from 0.5 Ω at 4.3 V to 1.65 Ω at 1.4 V. The component includes Schmitt trigger inputs for noise immunity and ESD protection exceeding 7500 V HBM.
Feature Summary
- Broadcast mode capability allows simultaneous signal transmission from the common port to all three independent ports.
- Low threshold digital inputs enable direct control by 1.8 V logic levels while switching signals up to 4.3 V.
- Break-before-make switching design prevents short circuits during channel transitions.
- High current handling capability supports continuous currents up to 350 mA under a 3.3 V supply.
Applications
- Cell phones
- Personal Digital Assistants (PDA)
- Portable media players
Procurement Notes
Verify the specific ordering suffix '115' against the manufacturer's latest documentation to confirm availability status and packaging details. Ensure that the XQFN10 package dimensions align with the target PCB footprint requirements. Confirm compliance with RoHS directives and REACH SVHC declarations prior to final procurement decisions.
Selection Notes
Select this component for applications requiring low signal attenuation and minimal distortion in portable electronics. The wide supply voltage range accommodates various battery-powered systems. Verify that the operating temperature range of -40 °C to +125 °C meets the environmental constraints of the intended deployment scenario.
Part Context
This part belongs to the NX3L series of analog switches designed for low-power consumer electronics. It serves as a multiplexer or demultiplexer in signal routing paths. The XQFN10 package provides a compact solution for space-constrained designs found in modern mobile devices and handheld gadgets.
Replacement Considerations
NX3L4357GM,132 is a documented variant within the same family but is marked as No Longer Manufactured. Verify functional compatibility if considering alternative SP3T switches from other manufacturers, ensuring pinout and electrical specifications match.
