Product details
Overview
NX3V1G66GM,115 from NXP Semiconductors is a low-ohmic SPST analog switch in XSON6 package, operating from 1.4 V to 4.3 V supply, featuring 0.25 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 delivers minimal signal attenuation in portable audio paths and high-fidelity sensor interfaces.
For engineers reviewing the NX3V1G66GM,115 datasheet, NX3V1G66GM,115 pinout, NX3V1G66GM,115 application, or NX3V1G66GM,115 equivalent, this device is selected for ultra-low RON, high ESD robustness (6 kV IEC contact), and operation across −40 °C to +125 °C - critical for space-constrained battery-powered systems requiring rail-to-rail analog switching.
Technical Context
The NX3V1G66GM,115 implements a CMOS transmission gate architecture with Schmitt-triggered enable logic, enabling reliable switching even with slow-rising control signals. Its flat RON (0.1 Ω typical) ensures consistent signal integrity across input voltage swing (0 V to VCC) and temperature (−40 °C to +125 °C).
Designed for bidirectional analog signal routing, it supports continuous 500 mA switch current at 3.3 V, exhibits −90 dB OFF-state isolation at 100 kHz, and maintains <0.01% THD at 20 Hz–20 kHz with 2 Vp-p input under 2.7 V+ supply - confirming suitability for audio and precision sensor front-ends.
Key Specifications

FAQ
What is the maximum continuous current rating for NX3V1G66GM,115?
The NX3V1G66GM,115 supports 500 mA continuous switch current when operated at 3.3 V supply voltage, as specified in the Absolute Maximum Ratings table. This rating applies to both Y and Z terminals under DC conditions with proper PCB thermal relief; pulsed current up to 750 mA is allowed at ≤10% duty cycle and 1 ms pulse width.
Does NX3V1G66GM,115 support rail-to-rail analog signal switching?
Yes, the NX3V1G66GM,115 allows signals with amplitude up to VCC to be transmitted bidirectionally between Y and Z terminals. Its CMOS transmission gate architecture ensures full rail-to-rail operation (0 V to VCC) without clipping or distortion, validated across the full −40 °C to +125 °C temperature range.
What is the purpose of the Schmitt trigger on the enable pin (E) of NX3V1G66GM,115?
The Schmitt trigger on the E pin of NX3V1G66GM,115 provides hysteresis (typically 0.3×VCC) to reject noise and tolerate slow input rise/fall times up to 200 ns/V. This eliminates false switching caused by GPIO bounce or long PCB traces, ensuring deterministic ON/OFF state transitions even with marginal control signals.
Can NX3V1G66GM,115 be used with a 1.5 V supply?
Yes, NX3V1G66GM,115 is fully specified down to 1.4 V supply voltage. At 1.5 V, it delivers 0.8 Ω typical ON resistance and maintains −90 dB OFF-state isolation, enabling use in ultra-low-power applications such as coin-cell-powered wearables or energy-harvesting sensor nodes where traditional 1.8 V switches fail to operate.
How does the XSON6 package of NX3V1G66GM,115 impact thermal performance?
The XSON6 (SOT886) package of NX3V1G66GM,115 features a 1.0 × 1.45 mm body with 0.5 mm height and thermal pad-less construction. Its total power dissipation is rated at 250 mW up to +125 °C ambient, with linear derating above 118 °C (7.8 mW/K). For 500 mA switching at 3.3 V, junction temperature rise remains within safe limits when mounted on standard 2-layer FR4 with 25 mm² copper pour.
