Product details
Overview
NX3L1T384GM,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 bidirectional signal routing between Y and Z terminals up to VCC amplitude - used in portable audio signal path switching.
For engineers reviewing the NX3L1T384GM,115 datasheet, NX3L1T384GM,115 pinout, NX3L1T384GM,115 application, or NX3L1T384GM,115 equivalent, key selection criteria include its 1.4–4.3 V wide supply range, 1.8 V logic compatibility at 3.6 V VCC, −40 °C to +125 °C operating temperature, and XSON6 package footprint for space-constrained mobile designs.
Technical Context
The NX3L1T384GM,115 implements a CMOS transmission gate architecture with Schmitt-trigger action on the E pin, enabling robust operation with slow-rising digital control signals and eliminating external level shifters when interfacing 1.8 V controllers with 4.3 V analog rails. Its flat ON resistance (0.13 Ω typical flatness at 2.7 V) ensures minimal signal distortion across the full input voltage range.
Designed for low-noise, low-distortion analog switching, it delivers −90 dB OFF-state isolation at 100 kHz, 60 MHz −3 dB bandwidth in ON-state, and <0.02% THD at 2.3 V and above - verified under 32 Ω load and 20 Hz–20 kHz conditions. Charge injection is limited to 3 pC (1.5–3.3 V) and 6 pC (4.3 V), supporting precision sampling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (typ) | 0.50 Ω at VCC = 2.7 V and 4.3 V - enables low-loss audio and sensor signal routing without gain compensation |
| Supply Voltage Range | 1.4 V to 4.3 V - supports direct integration into Li-ion battery-powered systems (2.7–4.2 V) and 1.8 V/3.3 V logic domains |
| Enable Input Threshold | VIL ≤ 0.6 V (max) at VCC = 4.3 V - guarantees reliable turn-on with 1.8 V GPIO without level translation |
| Switch Bandwidth | 60 MHz (−3 dB) - preserves integrity of high-speed analog signals including USB D+/D− and audio DAC outputs |
| OFF-State Isolation | −90 dB at 100 kHz - prevents crosstalk between adjacent channels in multi-input audio multiplexers |
| Operating Temperature | −40 °C to +125 °C - qualified for extended-temperature industrial and automotive infotainment subsystems |
| ESD Protection | HBM >7500 V, IEC61000-4-2 contact >4000 V - withstands handling and system-level ESD events without protection diodes |
Pinout & Package
Package: XSON6 (SOT886), plastic extremely thin small outline package, no leads, 6-terminal, body size 1.0 × 1.45 × 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Y) | Switch terminal A | Bidirectional analog I/O; connects to source or load depending on signal flow direction |
| 2 (Z) | Switch terminal B | Bidirectional analog I/O; complements Y port for SPST connection; supports rail-to-rail signal swing up to VCC |
| 3 (GND) | Ground reference | 0 V return path for internal circuitry and switch substrate; must be low-impedance for THD and isolation performance |
| 4 (E) | Active-low enable | Schmitt-triggered digital control input; LOW = ON state; tolerates slow edges and logic levels below VCC |
| 5 (n.c.) | No connect | Internally unconnected; must remain floating - not to be tied to GND, VCC, or other signals |
| 6 (VCC) | Positive supply | Power rail for analog switch core and enable logic; also defines maximum signal swing (0 to VCC) |
Key Features
| Feature | Design Value |
|---|---|
| 1.8 V logic-compatible control | Enables direct interface with 1.8 V microcontrollers at VCC = 3.6 V, removing need for discrete level translators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TS5A23157DCUR | 0.9 Ω typical RON at 3.3 V; 5-pin SOT-23 package; no Schmitt trigger on enable; 1.65–5.5 V supply | Lacks Schmitt-triggered enable and 1.8 V logic compatibility; requires external pull-up for clean enable edge | Choose when higher RON is acceptable and board layout allows larger SOT-23 footprint |
| Analog Devices ADG849YKSZ-REEL7 | 0.55 Ω typical RON at 3 V; 6-pin LFCSP (2 × 2 mm); −40 °C to +85 °C only; no 125 °C rating | Not qualified for extended temperature; lacks IEC61000-4-2 4000 V ESD rating on switch ports | Prefer for commercial-grade portable devices where 125 °C operation and system-level ESD immunity are not required |
Compared with TS5A23157DCUR and ADG849YKSZ-REEL7, the NX3L1T384GM,115 uniquely combines 125 °C operation, Schmitt-triggered 1.8 V logic compatibility, and 4000 V IEC61000-4-2 ESD protection - making it optimal for ruggedized portable electronics requiring zero-additional-components signal routing.

FAQ
What is the maximum continuous current rating for the NX3L1T384GM,115?
The NX3L1T384GM,115 supports 350 mA continuous current under 3.3 V supply, as specified in Table 5 of the datasheet. This rating applies to both Y and Z terminals in either direction and is validated over the full −40 °C to +125 °C operating range. Exceeding this current may cause thermal stress or parametric shift beyond guaranteed specifications.
Does the NX3L1T384GM,115 require external pull-up or pull-down resistors on the enable (E) pin?
No, the NX3L1T384GM,115 does not require external pull-up or pull-down resistors on the E pin because it features an integrated Schmitt trigger with defined VIH/VIL thresholds and negligible input leakage (<1 µA). The enable pin can be driven directly by open-drain or push-pull GPIOs without additional biasing components.
Can the NX3L1T384GM,115 switch signals exceeding the VCC supply voltage?
No, the NX3L1T384GM,115 cannot safely switch signals exceeding VCC. Per Table 6, the recommended switch voltage range is 0 to VCC. Absolute maximum ratings allow VSW up to VCC + 0.5 V transiently, but sustained operation above VCC risks latch-up or accelerated wear. For rail-to-rail analog signals, VCC must equal or exceed the peak signal amplitude.
Is the n.c. pin (pin 5) on the NX3L1T384GM,115 required to be left floating?
Yes, pin 5 (n.c.) on the NX3L1T384GM,115 must remain unconnected and floating - it is internally not bonded and has no electrical function. Connecting it to GND, VCC, or any signal violates the device's design intent and may compromise ESD performance or cause unpredictable behavior due to parasitic coupling.
How does the NX3L1T384GM,115 achieve 1.8 V logic compatibility while operating at 3.6 V VCC?
The NX3L1T384GM,115 achieves 1.8 V logic compatibility through a low-threshold Schmitt-trigger input circuit on the E pin, with VIL ≤ 0.6 V (max) at VCC = 3.6 V. This allows a 1.8 V GPIO LOW to reliably assert the enable function without requiring level translation, while maintaining high noise immunity via hysteresis.
