NX3L2267GM,115

Overview

The NX3L2267GM,115 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 features Schmitt trigger inputs for noise immunity. The device provides a typical ON resistance of 0.5 Ω at 2.7 V and supports bidirectional signal transmission up to VCC. It includes high ESD protection exceeding 7500 V (HBM) and latch-up performance over 100 mA. Packaged in a 10-XQFN (1.55x2 mm), it functions as a 2:1 multiplexer with break-before-make switching.

Feature Summary

• Dual SPDT configuration suitable for analog or digital 2:1 multiplexing applications
• Low threshold digital inputs enable direct control by 1.8 V logic levels without level translation
• Break-before-make switching action prevents signal overlap during transitions
• High current handling capability supporting continuous currents up to 350 mA

Applications

• Cell phones
• Personal Digital Assistants (PDA)
• Portable media players

Procurement Notes

Verify the component against the official NXP data sheet specifications before integration. Confirm that the XQFN10 package dimensions match the design footprint. Ensure operating conditions remain within the recommended voltage and temperature ranges to maintain specified electrical characteristics.

Selection Notes

Select this component when low ON resistance and minimal signal distortion are required in portable devices. It is appropriate for designs needing 1.8 V logic compatibility with higher voltage signal paths. Verify thermal dissipation requirements if operating near maximum current limits.

Part Context

This part belongs to the NX3L2267 series of low-ohmic analog switches. The GM suffix indicates the specific XQFN10 plastic package variant (SOT1049-3). The device is designed for space-constrained mobile electronics requiring reliable signal routing.

Replacement Considerations

NX3L2267GU,115 offers an alternative XQFN10 package (SOT1160-1) with identical electrical specifications.

FAQ

Can the NX3L2267 switch signals with amplitudes up to VCC?

Yes, the device allows signals with amplitude up to VCC to be transmitted bidirectionally between the common port (nZ) and independent ports (nY0/nY1).

What is the ESD protection rating for Human Body Model (HBM)?

The HBM JESD22-A114F Class 3A rating exceeds 7500 V.

How does the device handle slow input rise and fall times?

Schmitt trigger action at the digital inputs makes the circuit tolerant to slower input rise and fall times.
