Product details
Overview
NX3V1G66GW,125 from NXP Semiconductors is a low-ohmic SPST analog switch in TSSOP5 (SOT353-1) package, operating from 1.4 V to 4.3 V supply. It features 0.3 Ω typical ON resistance at 2.3 V, Schmitt-trigger enable input (E), and bidirectional Y/Z signal path supporting up to VCC amplitude - used for audio routing and sensor multiplexing in portable media players.
For engineers reviewing the NX3V1G66GW,125 datasheet, NX3V1G66GW,125 pinout, NX3V1G66GW,125 application, or NX3V1G66GW,125 equivalent, key selection criteria include ultra-low RON flatness (0.1 Ω), ±500 mA continuous switch current, −40 °C to +125 °C operation, and IEC61000-4-2 ESD robustness (6 kV contact) on switch ports.
Technical Context
The NX3V1G66GW,125 implements a CMOS transmission gate architecture with Schmitt-trigger input on the active-HIGH enable (E) pin, enabling reliable switching under slow-rising control signals. Its bidirectional conduction supports signal routing from Y to Z or Z to Y without polarity constraints.
Static performance is characterized by sub-1 Ω RON across 1.4–4.3 V supply range, <5 nA OFF-state leakage at 125 °C, and <7 μA supply current at 4.3 V - optimized for battery-powered systems requiring minimal quiescent power and signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 4.3 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 4.2 V Li-ion battery rails. |
| ON Resistance (Typ) | 0.3 Ω at VCC = 2.3 V - ensures <0.1% signal attenuation for 100 mA audio or sensor currents. |
| RON Flatness (Max) | 0.25 Ω at VCC = 4.3 V - maintains consistent gain/phase response across full signal swing (0 to VCC). |
| Switch Current Rating | ±500 mA continuous - supports high-fidelity audio paths and sensor excitation circuits. |
| ESD Robustness | 6 kV IEC61000-4-2 contact discharge on Y/Z ports - eliminates need for external TVS in handheld interfaces. |
| Operating Temperature | −40 °C to +125 °C - qualified for extended industrial and automotive cabin-adjacent applications. |
| Enable Propagation Delay | 15 ns typical at VCC = 3.6 V - supports fast reconfiguration in multi-channel audio or data acquisition systems. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package; 5 leads; body width 1.25 mm; pin 1 indicator located on lower left corner below marking code "dL".
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y | Bidirectional analog signal terminal - connects to source or load; voltage range 0 to VCC. |
| 2 | Z | Bidirectional analog signal terminal - mirror of Y; no polarity dependency in ON state. |
| 3 | GND | Analog/digital ground reference - must be low-impedance return for switch current and enable logic. |
| 4 | E | Active-HIGH enable with Schmitt trigger - accepts TTL levels at 3.0 V and tolerates slow edges (>200 ns/V). |
| 5 | VCC | Positive supply rail - powers internal logic and switch FETs; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RON flatness | 0.1 Ω max across full signal swing - preserves linearity in audio and precision sensor paths. |
| Wide supply compatibility | 1.4–4.3 V operation - eliminates level-shifting for mixed-voltage SoC interfaces (e.g., 1.8 V GPIO controlling 3.3 V audio bus). |
| High-current capability | ±500 mA continuous - enables direct driving of piezo buzzers, LED indicators, or resistive sensors without external buffers. |
| Robust ESD protection | 6 kV IEC61000-4-2 on Y/Z - meets EN 61000-4-2 Class 3 for handheld consumer electronics. |
| Low charge injection | 6.5 pC typical at VCC ≤ 3.3 V - minimizes glitch-induced offset in precision ADC front-ends and sample-hold circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DCUR | RON = 0.9 Ω (typ) at 3.3 V; 6-pin SOT-23 package; no Schmitt trigger on enable. | Limited to 3.3 V only; higher RON increases insertion loss in audio paths. | Prefer NX3V1G66GW,125 for wide-VCC, low-distortion, or slow-control-signal designs. |
| ADG801BRMZ-REEL7 | RON = 0.3 Ω (typ) at 3 V; 8-pin MSOP; requires external pull-up on enable; no integrated ESD on switch pins. | Higher BOM cost and board area; lacks IEC61000-4-2 rated switch port protection. | Choose NX3V1G66GW,125 when compact 5-pin layout, integrated ESD, and Schmitt-trigger enable are required. |
Compared with TS5A23157DCUR and ADG801BRMZ-REEL7, the NX3V1G66GW,125 delivers superior RON flatness (0.1 Ω), wider supply range (1.4–4.3 V), and system-level ESD robustness - reducing external protection components and simplifying layout in space-constrained portable designs.

FAQ
What is the maximum continuous current rating for the NX3V1G66GW,125?
The NX3V1G66GW,125 supports ±500 mA continuous current through its Y–Z switch path when supplied at 3.3 V, as specified in Table 5 (Limiting Values). This rating applies under recommended operating conditions with proper PCB thermal relief and ambient temperature ≤ +125 °C. Derating is required above 87.5 °C per the Ptot derating curve.
Does the NX3V1G66GW,125 support bidirectional signal flow between Y and Z terminals?
Yes, the NX3V1G66GW,125 is a fully bidirectional analog switch: signals can pass from Y to Z or Z to Y with identical RON, capacitance, and leakage characteristics. Its CMOS transmission gate structure imposes no polarity constraints, and the voltage range on either terminal is 0 V to VCC - confirmed in Section 1 (General description) and Table 3 (Pin description).
What ESD protection levels does the NX3V1G66GW,125 provide on its Y and Z switch terminals?
The NX3V1G66GW,125 provides IEC61000-4-2 contact discharge ESD protection exceeding 6000 V on its Y and Z switch ports, as stated in Section 2 (Features and benefits). This is independent of HBM (7500 V), MM (200 V), and CDM (1000 V) ratings - all verified per JEDEC standards and documented in the official NXP product data sheet Rev. 7.
Can the NX3V1G66GW,125 operate with a 1.4 V supply voltage while maintaining guaranteed performance?
Yes, the NX3V1G66GW,125 is fully specified from 1.4 V to 4.3 V per Table 6 (Recommended operating conditions). At 1.4 V, RON is 0.8 Ω (typ) and enable timing remains functional (ten = 42 ns max), enabling use in ultra-low-power wearables and energy-harvesting systems - all parameters validated across −40 °C to +125 °C.
Is the enable input (E) of the NX3V1G66GW,125 compatible with standard TTL logic levels?
Yes, the NX3V1G66GW,125 enable input accepts TTL-level signals directly at 3.0 V supply, as explicitly stated in Section 2 (Features and benefits). Its Schmitt-trigger input ensures noise immunity, and VIH/VIL thresholds scale with VCC - e.g., VIH = 2.0 V min at VCC = 2.7–3.6 V - allowing reliable interfacing with legacy 3.3 V microcontrollers without level shifters.
