Product details
Overview
NX3L2G384GM,125 from NXP Semiconductors is a dual low-ohmic SPST analog switch with active-low enable inputs (1E, 2E), bidirectional signal routing between Y/Z terminals, 0.5 Ω typical ON resistance at 2.7 V and 4.3 V supply, and operation across −40 °C to +125 °C. It enables high-fidelity audio and data path switching in space-constrained portable electronics.
For engineers reviewing the NX3L2G384GM,125 datasheet, NX3L2G384GM,125 pinout, NX3L2G384GM,125 application, or NX3L2G384GM,125 equivalent, key selection criteria include its 0.13 Ω ON-resistance flatness, ±350 mA continuous switch current, Schmitt-trigger enable inputs for slow-edge tolerance, and XQFN8 package compatibility with high-density PCB layouts.
Technical Context
The NX3L2G384GM,125 implements two independent CMOS transmission gates, each controlled by a dedicated active-low enable input with Schmitt-trigger hysteresis-ensuring robust noise immunity against slow-rising/falling control signals. Its bidirectional architecture supports signal flow from Y to Z or Z to Y without polarity constraints.
Designed for low-voltage operation (1.4 V to 4.3 V), it delivers sub-1 Ω typical ON resistance across the full supply range and maintains <0.4 V maximum voltage drop under 350 mA load-critical for minimizing distortion in audio and sensor signal paths. ESD protection exceeds 7500 V HBM and 4000 V IEC61000-4-2 on switch ports.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DCUR | Single-supply 1.65–5.5 V; 0.9 Ω typical RON at 3.3 V; SOT-23-6 package (6-pin) | Single-channel only; lacks dual independent enables; higher RON increases insertion loss | Select when board space permits larger footprint and dual-channel independence is unnecessary |
| ADG884BRMZ | 1.8–5.5 V supply; 0.35 Ω typical RON at 3 V; MSOP-10 package; −40 °C to +125 °C rated | Higher pin count; requires level-shifting for 1.4 V operation; no Schmitt-trigger enables | Prefer when ultra-low RON is critical and system supports 1.8 V minimum supply |
Compared with TS5A23157DCUR and ADG884BRMZ, the NX3L2G384GM,125 uniquely combines dual independent SPST switches, 1.4 V minimum operation, Schmitt-trigger enables, and XQFN8 packaging-enabling compact, low-distortion signal routing where supply headroom and layout density are constrained.

FAQ
What is the maximum continuous current rating for NX3L2G384GM,125?
The NX3L2G384GM,125 supports ±350 mA continuous current per switch channel at 3.3 V supply, verified across −40 °C to +125 °C. This rating applies under conditions where the voltage drop across the switch remains ≤0.4 V-ensuring safe operation with 16 Ω headphone loads and sensor excitation circuits without thermal derating.
Does NX3L2G384GM,125 support operation below 1.4 V?
No. The NX3L2G384GM,125 is specified for 1.4 V to 4.3 V supply operation per its recommended conditions. Operation below 1.4 V is not characterized and may result in undefined enable threshold behavior, increased ON resistance, or failure to meet timing specifications. The device is not guaranteed functional below 1.4 V.
How does the Schmitt-trigger enable input improve system reliability in NX3L2G384GM,125?
The Schmitt-trigger action on pins 1E and 2E provides hysteresis (typically 0.35VCC to 0.7VCC), allowing the NX3L2G384GM,125 to tolerate slow-rising or noisy control signals-common in low-power microcontroller GPIOs or mechanically switched inputs. This prevents chatter-induced partial conduction and ensures clean, deterministic switching transitions even with edge rates as low as 200 ns/V.
Can NX3L2G384GM,125 be used in automotive cabin applications?
Yes. The NX3L2G384GM,125 is qualified for −40 °C to +125 °C operation and meets stringent ESD requirements (7500 V HBM, 4000 V IEC61000-4-2), making it suitable for non-safety-critical automotive cabin applications such as infotainment audio routing, climate control sensor multiplexing, and telematics interface switching-provided it is not deployed in ASIL-B or higher safety domains.
What is the typical THD performance of NX3L2G384GM,125 in audio applications?
At VCC = 2.7 V and 4.3 V, the NX3L2G384GM,125 achieves ≤0.02% total harmonic distortion (THD) for 2 Vp-p signals across 20 Hz–20 kHz with 32 Ω load. This performance is enabled by its 0.5 Ω typical ON resistance, 0.13 Ω flatness, and low charge injection (<3 pC), ensuring minimal waveform distortion during analog signal switching in portable audio systems.
