Product details
Overview
NX3L1T66GM,115 from NXP Semiconductors is a low-ohmic single-pole single-throw (SPST) analog switch in XSON6 package, operating from 1.4 V to 4.3 V supply. It features 0.50 Ω typical ON resistance at 2.7 V and 4.3 V, Schmitt-trigger enable input (E), and bidirectional signal routing between Y and Z terminals. It enables 4.3 V analog signal switching using a 1.8 V digital controller without level translation - ideal for portable audio routing in space-constrained handheld devices.
For engineers reviewing the NX3L1T66GM,115 datasheet, NX3L1T66GM,115 pinout, NX3L1T66GM,115 application, or NX3L1T66GM,115 equivalent, key selection criteria include its ultra-low RON flatness (0.13 Ω), −40 °C to +125 °C extended temperature range, 350 mA continuous current capability, and IEC61000-4-2 ESD robustness (4 kV contact discharge on switch ports).
Technical Context
The NX3L1T66GM,115 implements a CMOS transmission gate architecture with Schmitt-trigger action on the active-HIGH enable (E) pin, enabling tolerance to slow digital edge rates and compatibility with sub-VCC logic drive (e.g., 1.8 V control at 3.6 V VCC). Its bidirectional Y–Z path supports signal amplitudes up to VCC, with leakage currents limited to ±500 nA over full temperature range.
Dynamic performance includes 11 ns disable time (tdis) and 18 ns enable time (ten) at VCC = 3.6 V to 4.3 V, −3 dB bandwidth of 60 MHz, and isolation of −90 dB at 100 kHz in OFF-state. Charge injection is tightly controlled at 3 pC (1.5–3.3 V) and 6 pC (4.3 V), minimizing transient glitches in precision signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.4 V to 4.3 V - supports direct interface with Li-ion battery rails and mixed-voltage SoC I/O domains. |
| ON resistance (typical) | 0.50 Ω at VCC = 2.7 V and 4.3 V - ensures minimal insertion loss (<0.01 dB) for 32 Ω audio loads. |
| RON flatness | 0.13 Ω at VCC = 2.7 V - maintains consistent signal amplitude across full analog swing, critical for THD-sensitive audio paths. |
| Switch current rating | ±350 mA continuous - handles high-drive headphone outputs and sensor excitation signals without thermal derating at Tamb ≤ 118 °C. |
| ESD protection | IEC61000-4-2 contact discharge ≥ 4000 V on Y/Z ports - eliminates need for external TVS diodes in consumer handheld ESD zones. |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood adjacent modules and industrial portable equipment with extended thermal margins. |
| Enable propagation delay | 18 ns max (ten/tdis at VCC ≥ 2.7 V) - supports fast channel switching in multi-source audio multiplexers. |
Pinout & Package
XSON6 (SOT886) package: plastic extremely thin small outline, no leads, 6-terminal, body size 1.0 mm × 1.45 mm × 0.5 mm, wettable flank compatible for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Y) | Independent analog I/O terminal | Bidirectional signal path; connects to source (e.g., codec DAC) or load (e.g., speaker driver) without polarity constraint. |
| 2 (Z) | Independent analog I/O terminal | Paired with Y to form SPST switch; identical electrical characteristics - interchangeable in layout. |
| 3 (GND) | Ground reference | Low-impedance return for switch conduction and internal biasing; must be connected to system analog ground plane. |
| 4 (E) | Active-HIGH enable input | Schmitt-triggered logic input; accepts 0–4.3 V drive; enables switch when ≥1.3 V (VCC = 2.7–3.6 V) or ≥1.4 V (VCC = 3.6–4.3 V). |
| 5 (n.c.) | No-connect terminal | Internally unconnected; must remain floating - no PCB trace or solder mask opening required. |
| 6 (VCC) | Positive supply rail | Power for analog switch core and enable logic; decoupling capacitor (100 nF) recommended within 2 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Sub-VCC logic compatibility | Enables 1.8 V GPIO control at VCC = 3.6 V - eliminates level shifters in mixed-voltage portable systems. |
| Ultra-low charge injection | 3 pC typical (VCC ≤ 3.3 V) - prevents audible pop/click in headset switching applications. |
| High OFF-state isolation | −90 dB at 100 kHz - suppresses crosstalk between adjacent audio channels in multi-input receivers. |
| Flat RON vs. signal voltage | 0.13 Ω variation across full 0–VCC swing at 2.7 V - preserves linearity in precision sensor signal conditioning. |

FAQ
What is the maximum continuous current rating for the NX3L1T66GM,115?
The NX3L1T66GM,115 supports ±350 mA continuous current at VCC = 3.3 V, verified across −40 °C to +125 °C ambient. This rating applies to both Y→Z and Z→Y conduction directions and is limited by thermal dissipation in the XSON6 package. Derating begins above 118 °C per the 7.8 mW/K slope specified in the datasheet.
Does the NX3L1T66GM,115 require external level translation when driven by a 1.8 V microcontroller?
No - the NX3L1T66GM,115 does not require external level translation. Its Schmitt-trigger enable input accepts 1.8 V logic directly at VCC = 3.6 V, with VIH threshold of 1.3 V (min). This allows direct GPIO control from low-voltage controllers while maintaining noise immunity and eliminating discrete level-shifter components.
What is the OFF-state leakage current specification for NX3L1T66GM,115 over temperature?
The NX3L1T66GM,115 specifies ±500 nA maximum OFF-state leakage current (IS(OFF)) for both Y and Z terminals over the full −40 °C to +125 °C operating range at VCC ≤ 3.6 V. At VCC = 4.3 V, the limit increases to ±500 nA, ensuring predictable signal blocking in precision sensor and audio applications.
Can the NX3L1T66GM,115 switch signals exceeding its VCC supply voltage?
No - the NX3L1T66GM,115 is rated for switch voltages from 0 V to VCC only. Exceeding VCC on Y or Z violates the absolute maximum rating (VSW ≤ VCC + 0.5 V) and risks latch-up or permanent damage. For signals beyond VCC, a different topology (e.g., back-to-back FETs or dedicated high-voltage switch) is required.
Is the NX3L1T66GM,115 automotive-qualified?
No - the NX3L1T66GM,115 is not automotive-qualified. While it operates from −40 °C to +125 °C, it is not tested or certified to AEC-Q100 standards. NXP explicitly states that non-automotive qualified products like the NX3L1T66GM,115 are unsuitable for safety-critical or automotive applications unless independently validated by the customer.
