Product details
Overview
NX3V1T66GW,125 from NXP Semiconductors is a low-ohmic SPST analog switch in TSSOP5 package, operating from 1.4 V to 4.3 V supply, featuring 0.25 Ω typical ON resistance at 4.3 V, Schmitt-trigger enable input (E), and bidirectional Y–Z signal routing up to VCC amplitude. It enables 1.8 V logic control of 4.3 V analog signals in portable audio paths.
For engineers reviewing the NX3V1T66GW,125 datasheet, NX3V1T66GW,125 pinout, NX3V1T66GW,125 application, or NX3V1T66GW,125 equivalent, key selection criteria include ultra-low RON flatness (0.1 Ω), −40 °C to +125 °C operation, ESD robustness (6 kV IEC61000-4-2), and 500 mA continuous current handling without level translation.
Technical Context
The NX3V1T66GW,125 implements a CMOS transmission gate architecture with Schmitt-trigger enable input for noise immunity and slow-edge tolerance. Its voltage-tolerant enable accepts inputs up to 4.6 V independent of VCC, enabling direct interfacing with higher-voltage controllers while powered from 1.4 V–4.3 V.
Signal path supports bidirectional analog switching between Y and Z terminals with minimal distortion: THD ≤0.01% at 20 kHz (VCC ≥2.3 V), −3 dB bandwidth ≥25 MHz, and charge injection ≤12 pC (VCC = 4.3 V). OFF-state isolation exceeds −90 dB at 100 kHz.
Key Specifications

FAQ
What is the maximum signal voltage the NX3V1T66GW,125 can pass?
The NX3V1T66GW,125 supports bidirectional analog signal transmission with amplitude up to VCC. When VCC = 4.3 V, the device passes signals from 0 V to 4.3 V on both Y and Z terminals. Absolute maximum switch voltage is VCC + 0.5 V (4.8 V), but operation beyond VCC is not recommended for signal integrity. The NX3V1T66GW,125 does not support rail-to-rail operation above its supply rail.
Can the NX3V1T66GW,125 be used with a 1.8 V microcontroller controlling a 3.3 V analog signal path?
Yes. The NX3V1T66GW,125's Schmitt-trigger enable input accepts 1.8 V logic levels directly at VCC = 3.3 V, with VIH = 1.3 V (min) and VIL = 0.5 V (max). Its voltage-tolerant enable allows 1.8 V GPIO to reliably turn on/off the switch without level translation, and the 0.25 Ω RON ensures minimal attenuation of the 3.3 V analog signal. This capability is explicitly validated in the NX3V1T66GW,125 datasheet.
Does the NX3V1T66GW,125 require external ESD protection on its Y and Z pins?
No. The NX3V1T66GW,125 integrates IEC61000-4-2 contact discharge ESD protection rated at 6000 V on its Y and Z switch terminals, exceeding typical system-level requirements for handheld devices. External TVS diodes are unnecessary unless the application demands >6 kV protection or involves unusual transient waveforms not covered by the IEC standard. The NX3V1T66GW,125's built-in protection is verified per industry-standard test methods.
What is the thermal performance of the NX3V1T66GW,125 in TSSOP5 package at +125 °C ambient?
In the TSSOP5 (SOT353-1) package, the NX3V1T66GW,125 has a total power dissipation limit of 250 mW at Tamb = −40 °C to +125 °C, with linear derating above 87.5 °C at 4.0 mW/K. At +125 °C ambient and 500 mA load, self-heating remains within safe limits due to its ultra-low RON (0.25 Ω), resulting in only ~62.5 mW conduction loss. The NX3V1T66GW,125 is fully specified and tested across this full temperature range.
How does the NX3V1T66GW,125 achieve low THD in audio applications?
The NX3V1T66GW,125 achieves ≤0.01% THD at 20 kHz via ultra-low and flat ON resistance (0.25 Ω typical, 0.1 Ω flatness), symmetric CMOS transmission gate design, and optimized charge injection (<12 pC). These features minimize nonlinear distortion and intermodulation when switching audio signals up to VCC. THD performance is measured and guaranteed per Figure 17 in the NX3V1T66GW,125 datasheet under defined load and frequency conditions.
