Product details
Overview
NX3L2G384GD,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, Schmitt-triggered enables for noise immunity, and operation across −40 °C to +125 °C. It supports rail-to-rail analog signal transmission up to VCC in portable audio and interface switching applications.
For engineers reviewing the NX3L2G384GD,125 datasheet, NX3L2G384GD,125 pinout, NX3L2G384GD,125 application, or NX3L2G384GD,125 equivalent, key selection criteria include its 0.13 Ω ON-resistance flatness, 350 mA continuous switch current, ESD robustness (4 kV IEC61000-4-2 contact), and XSON8 (SOT996-2) 3 × 2 × 0.5 mm package compatibility with high-density portable designs.
Technical Context
The NX3L2G384GD,125 implements two independent CMOS transmission gates with active-low enable logic and Schmitt-triggered inputs, enabling reliable switching under slow-rising control signals. Its bidirectional architecture allows signal flow from Y to Z or Z to Y without polarity constraints.
Designed for low-voltage mixed-signal systems, it operates from 1.4 V to 4.3 V supply, maintains sub-1 Ω ON resistance across temperature (−40 °C to +125 °C), and delivers 60 MHz −3 dB bandwidth with <0.02% THD at 2.3 V–4.3 V, supporting high-fidelity audio and data path switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (typ) | 0.50 Ω at VCC = 2.7 V and 4.3 V - ensures minimal insertion loss and voltage drop in signal paths |
| ON Resistance Flatness (typ) | 0.13 Ω at VCC = 2.7 V - guarantees consistent signal attenuation across input voltage range |
| Switch Current (cont) | ±350 mA at 3.3 V - supports driving moderate loads such as audio codecs or sensor interfaces |
| ESD Rating (IEC61000-4-2) | 4000 V contact discharge on switch ports - protects against handling-induced transients in end-user devices |
| Operating Temperature | −40 °C to +125 °C - qualified for extended industrial and automotive cabin-adjacent environments |
| Enable Propagation Delay | 14 ns typical enable time at VCC ≥ 2.7 V - enables fast channel selection in time-critical multiplexing |

Applications
| Audio Signal Routing | USB Data Line Switching |
|---|---|
|
Use Scenario: Selecting between stereo headset and speaker outputs in smartphones or portable media players. IC Role / Device Role / Timing Role: Dual SPST analog switch managing bidirectional audio paths with minimal crosstalk and distortion. Use Value: 0.02% THD at 2.3 V+ and 60 MHz bandwidth preserve fidelity; 0.13 Ω flatness prevents volume imbalance between channels. |

IC Role / Device Role / Timing Role: Low-capacitance (110 pF ON-state), low-RON switch enabling transparent USB 1.1 signal pass-through. Use Value: 35 pF OFF-state capacitance and 60 MHz −3 dB bandwidth maintain signal integrity; ±350 mA rating handles hot-plug surge currents. |
| Camera Interface Multiplexing | Industrial Sensor Signal Conditioning |
|
Use Scenario: Sharing a single MIPI CSI-2 receiver between front/rear cameras in compact mobile devices. IC Role / Device Role / Timing Role: High-isolation (−90 dB OFF-state) analog switch isolating unused camera signal paths. Use Value: −90 dB isolation prevents interference between active/inactive sensors; 14 ns enable time supports rapid camera switching. |
Use Scenario: Routing analog sensor outputs (e.g., temperature, pressure) to ADC inputs in programmable logic controllers. IC Role / Device Role / Timing Role: Precision analog switch with low charge injection (3 pC typical) minimizing ADC offset errors. Use Value: 3 pC charge injection at 1.5–3.3 V reduces measurement drift; −40 °C to +125 °C rating matches industrial ambient requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DCUR | 2-channel level translator with auto-direction sensing; not a pure analog switch; higher ON resistance (6 Ω typical) | Requires direction control logic; unsuitable for AC-coupled or bidirectional analog signals like audio | Select only when level translation-not analog signal routing-is the primary requirement |
| TMUX1574RSVR | Single-supply 4-channel SPDT; 0.7 Ω typical RON at 3.3 V; smaller 1.6 × 1.6 mm XQFN8 package | Higher channel count but larger footprint per switch; lacks Schmitt-triggered enables | Prefer for space-constrained multi-channel routing where enable noise immunity is less critical |
Compared with TXS0102DCUR and TMUX1574RSVR, the NX3L2G384GD,125 offers superior analog fidelity (0.13 Ω flatness, 0.02% THD), integrated noise-immune enables, and optimized 3 × 2 mm XSON8 layout for dual-channel portable signal routing-making it the preferred choice for high-integrity audio and interface switching.

FAQ
What is the maximum continuous current rating for the NX3L2G384GD,125?
The NX3L2G384GD,125 supports ±350 mA continuous current per switch at 3.3 V supply, verified across −40 °C to +125 °C. This rating applies under recommended operating conditions with proper PCB thermal relief; peak pulsed current reaches ±500 mA for ≤1 ms at <10% duty cycle.
Does the NX3L2G384GD,125 support rail-to-rail analog signal transmission?
Yes, the NX3L2G384GD,125 allows analog signals with amplitude up to VCC to be transmitted bidirectionally between Y and Z terminals. Its CMOS transmission gate architecture enables true rail-to-rail operation without level-shifting circuitry when VCC is the system's highest supply rail.
What package type is used for the NX3L2G384GD,125?
The NX3L2G384GD,125 uses the XSON8 package (JEDEC designation SOT996-2): a leadless, extremely thin small outline package measuring 3.0 mm × 2.0 mm × 0.5 mm with 8 terminals. Pin 1 is located in the lower-left corner below the marking code "ML2".
How does the Schmitt-trigger action on the enable inputs benefit system design?
The Schmitt-triggered enable inputs (1E, 2E) of the NX3L2G384GD,125 provide hysteresis (typically 0.35×VCC to 0.7×VCC thresholds), making the device tolerant to slow-rising/falling control signals and reducing susceptibility to noise-induced false switching in noisy portable environments.
Is the NX3L2G384GD,125 qualified for automotive applications?
No-the NX3L2G384GD,125 is specified for −40 °C to +125 °C operation but is not AEC-Q200 qualified. NXP explicitly states in its datasheet that non-automotive qualified products like the NX3L2G384GD,125 are not tested to automotive reliability standards and should not be used in safety-critical vehicle systems.
