Product details
Overview
NX3L1G384GM,115 from NXP Semiconductors is a low-ohmic single-pole single-throw (SPST) analog switch with active-low enable control, 0.5 Ω typical ON resistance at 2.7 V and 4.3 V supply, Schmitt-triggered enable input for noise immunity, and operation across −40 °C to +125 °C. It routes bidirectional analog signals up to VCC between Y and Z terminals in portable audio signal paths.
For engineers reviewing the NX3L1G384GM,115 datasheet, NX3L1G384GM,115 pinout, NX3L1G384GM,115 application, or NX3L1G384GM,115 equivalent, key selection criteria include ON-resistance flatness (0.13 Ω), 350 mA continuous switch current, ESD robustness (4 kV IEC61000-4-2), and XSON6 package compatibility with high-density portable PCB layouts.
Technical Context
The NX3L1G384GM,115 implements a CMOS transmission-gate topology with rail-to-rail analog signal handling (0 V to VCC) and bidirectional conduction. Its Schmitt-triggered enable input accepts TTL-level signals at 3.0 V and tolerates slow edge rates (≤200 ns/V), eliminating external debouncing circuitry.
It features low charge injection (3 pC at 1.5–3.3 V), −90 dB OFF-state isolation at 100 kHz, and 60 MHz −3 dB bandwidth in ON-state-enabling high-fidelity audio switching without distortion or crosstalk in battery-powered devices.
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 voltage drop and signal attenuation in audio/data paths |
| ON Resistance Flatness (typ) | 0.13 Ω at VCC = 2.7 V - maintains consistent gain and linearity across full input voltage range |
| Switch Current (cont) | ±350 mA at 3.3 V - supports high-drive headphone or sensor interface loads without derating |
| ESD Protection | 4000 V IEC61000-4-2 contact discharge on switch ports - enables direct integration into exposed I/O interfaces |
| Operating Temperature | −40 °C to +125 °C - qualified for extended thermal environments in automotive infotainment and industrial handhelds |
| Enable Propagation Delay | 14 ns typ (VCC ≥ 2.7 V) - allows fast channel switching in time-critical multiplexing applications |
| Supply Voltage Range | 1.4 V to 4.3 V - compatible with single-cell Li-ion, 1.8 V logic, and 3.3 V system rails |
Pinout & Package
XSON6 (SOT886) plastic extremely thin small outline package; no leads; 6-terminal body measuring 1.0 × 1.45 × 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Y) | Independent analog I/O terminal | Bidirectional signal path - connects to source or load without polarity restriction |
| 2 (Z) | Independent analog I/O terminal | Paired with Y; forms SPST switch path - no internal routing preference |
| 3 (GND) | Ground reference | 0 V return for all internal circuitry and switch substrate - must be low-impedance |
| 4 (E) | Active-low enable input | Schmitt-triggered logic control - immune to noise on enable line; HIGH disables switch |
| 5 (n.c.) | No-connect terminal | Internally unconnected - must remain floating; no external connection permitted |
| 6 (VCC) | Positive supply | Power rail for analog and digital sections - decoupling capacitor required within 1 mm |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Signals from 0 V to VCC pass bidirectionally with <0.5 Ω resistance - preserves dynamic range in audio codecs |
| Low charge injection | 3 pC typical (1.5–3.3 V) - prevents DC offset glitches during channel switching in precision sensor front-ends |
| High OFF-state isolation | −90 dB at 100 kHz - suppresses crosstalk between adjacent audio channels or data lines |
| Wide supply compatibility | Operates from 1.4 V to 4.3 V - eliminates level-shifting in mixed-voltage portable systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DCUR | Higher ON resistance (0.9 Ω typ at 3.3 V); no Schmitt trigger on enable; 0.75 V minimum supply | Limited to 3.3 V systems; less tolerant of noisy control lines | Choose when lower cost outweighs need for sub-0.6 Ω RON and Schmitt-trigger noise immunity |
| ADG801BRMZ-REEL7 | Lower leakage (1 nA max OFF-state); higher supply max (5.5 V); larger MSOP-8 package | Requires PCB redesign due to 8-pin footprint and 3× larger area | Prefer when ultra-low leakage dominates over board space and thermal performance |
Compared with TS5A23157DCUR and ADG801BRMZ-REEL7, the NX3L1G384GM,115 delivers superior ON-resistance flatness (0.13 Ω) and integrated Schmitt triggering in a 1.0 × 1.45 mm XSON6 package-making it optimal for space-constrained, noise-prone portable audio and sensor routing where signal integrity is critical.

FAQ
What is the maximum continuous current rating for the NX3L1G384GM,115?
The NX3L1G384GM,115 supports ±350 mA continuous switch current at 3.3 V supply, verified per Table 5 Limiting Values. This rating applies under recommended operating conditions (Tamb ≤ +125 °C, VSW within 0 V to VCC). Exceeding this current may cause thermal shutdown or permanent damage.
Does the NX3L1G384GM,115 require external pull-up or pull-down resistors on the enable (E) pin?
No, the NX3L1G384GM,115 does not require external biasing on the E pin. Its Schmitt-trigger input provides hysteresis and defined switching thresholds (e.g., VIL ≤ 0.35VCC, VIH ≥ 0.65VCC), allowing direct connection to GPIOs or open-drain drivers without pull resistors.
Can the NX3L1G384GM,115 operate with a 1.4 V supply voltage?
Yes, the NX3L1G384GM,115 is fully specified down to 1.4 V supply, with 1.6 Ω typical ON resistance and 41 ns maximum enable time at that voltage. All static and dynamic parameters in Tables 6–9 are guaranteed across the full 1.4 V to 4.3 V range.
What is the meaning of "n.c." on pin 5 of the NX3L1G384GM,115?
"n.c." stands for "no connect" - pin 5 of the NX3L1G384GM,115 is internally unconnected and must remain electrically floating. Soldering or tying this pin to any voltage violates the device's absolute maximum ratings and may compromise ESD performance or parametric yield.
How does the NX3L1G384GM,115 handle signals exceeding VCC?
The NX3L1G384GM,115 does not support signals above VCC. Per Table 5 Limiting Values, the maximum switch voltage is VCC + 0.5 V. Exceeding this risks latch-up or permanent damage. For overvoltage-tolerant switching, consider NXP's NX3DVxx family or discrete clamp solutions.
