Product details
Overview
NX3V1T384GM,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 (active LOW), and bidirectional signal routing between Y and Z terminals. It enables precision analog path switching in portable audio and data interfaces.
For engineers reviewing the NX3V1T384GM,115 datasheet, NX3V1T384GM,115 pinout, NX3V1T384GM,115 application, or NX3V1T384GM,115 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 NX3V1T384GM,115 implements a CMOS transmission gate architecture with Schmitt-trigger action on the active-LOW enable (E) input, ensuring noise immunity against slow-rising/falling control signals. Its bidirectional Y–Z path supports rail-to-rail analog signals up to VCC, with minimal distortion due to ultra-flat ON resistance (0.1 Ω max variation).
Static leakage is tightly controlled: OFF-state leakage ≤ ±500 nA over full temperature range, and supply current ≤ 7 µA at 4.3 V. Dynamic performance includes 5 ns disable time (VCC ≥ 2.7 V) and −90 dB OFF-isolation at 100 kHz, making it suitable for high-fidelity audio and low-noise sensor multiplexing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.4 V to 4.3 V - Enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 4.3 V logic and analog rails without level shifting. |
| ON Resistance (Typ) | 0.25 Ω at VCC = 2.7 V and 4.3 V - Ensures <0.01% signal attenuation for 100 mA analog paths; critical for precision instrumentation. |
| ON Resistance Flatness | 0.1 Ω - Minimal RON variation across signal swing preserves THD <0.01% at 2.3 V+ supplies. |
| Switch Current | ±500 mA continuous - Supports high-drive applications like speaker switching or battery path control without derating. |
| ESD Robustness | 6 kV IEC61000-4-2 contact discharge on Y/Z ports - Eliminates need for external TVS in handheld device front-end interfaces. |
| Operating Temperature | −40 °C to +125 °C - Qualified for extended industrial and automotive cabin-adjacent environments. |
| Disable Time | 5 ns max at VCC ≥ 2.7 V - Enables fast channel blanking in time-division multiplexed systems (e.g., ADC sampling guards). |
Pinout & Package
XSON6 (SOT886) package: plastic extremely thin small outline, no leads, 6-terminal, body size 1.0 × 1.45 × 0.5 mm, thermal pad exposed on bottom (non-electrical), pin 1 indicator in lower-left corner below marking code "eL".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Y) | Switch terminal A | Bidirectional analog I/O; connects to signal source or load; voltage range: 0 V to VCC. |
| 2 (Z) | Switch terminal B | Bidirectional analog I/O; complements Y; same voltage and current ratings as Y. |
| 3 (GND) | Ground reference | 0 V return for internal circuitry and ESD protection network; must be low-impedance. |
| 4 (E) | Enable input (active LOW) | Schmitt-triggered control; HIGH = switch OFF, LOW = switch ON; accepts voltages > VCC. |
| 5 (n.c.) | No connect | Internally unconnected; must be left floating or tied to GND per layout best practice. |
| 6 (VCC) | Positive supply | Power rail for analog switch core and enable logic; decoupling capacitor required within 2 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports signals from GND to VCC without clipping - essential for full-scale audio and sensor outputs. |
| Ultra-low charge injection | 6.5 pC at VCC ≤ 3.3 V - Minimizes glitch-induced offset in precision sample-and-hold and mux-based ADC front-ends. |
| High OFF-isolation | −90 dB at 100 kHz - Prevents crosstalk between adjacent channels in multi-input audio codecs or sensor arrays. |
| Wide supply compatibility | Operates down to 1.4 V - Enables integration into ultra-low-power wearable SoC subsystems with single-cell Li-ion or coin-cell supplies. |
| Robust ESD on switch ports | 6 kV IEC61000-4-2 contact discharge - Allows direct PCB-level connection to USB, headphone, or antenna interfaces without guard traces. |

FAQ
What is the maximum continuous current rating for the NX3V1T384GM,115?
The NX3V1T384GM,115 supports ±500 mA continuous current through its Y–Z switch path when supplied at 3.3 V, as specified in Table 5 (Limiting Values) of the NXP datasheet Rev. 6. This rating applies across the full −40 °C to +125 °C operating range and enables use in speaker switching and power-path applications without external current limiting.
Does the NX3V1T384GM,115 require external pull-up or pull-down resistors on the enable (E) pin?
No, the NX3V1T384GM,115 does not require external biasing on the E pin because it integrates a Schmitt-trigger input with defined VIH/VIL thresholds across all supply voltages (e.g., VIH = 2.0 V min at VCC = 2.7–3.6 V). The internal hysteresis ensures clean switching even with slow-rising control signals, eliminating need for external RC networks.
Can the NX3V1T384GM,115 pass signals exceeding the VCC rail?
No, the NX3V1T384GM,115 cannot pass signals exceeding VCC or going below GND. Its absolute maximum switch voltage is VCC + 0.5 V (per Table 5), and recommended operating conditions limit VSW to 0 V to VCC. Exceeding this risks latch-up or permanent damage; rail-to-rail operation is supported only within the supply bounds.
What is the thermal pad on the NX3V1T384GM,115 XSON6 package used for?
The exposed thermal pad on the NX3V1T384GM,115 XSON6 (SOT886) package is electrically isolated and intended solely for thermal conduction to the PCB ground plane. It must be soldered to a thermal copper pour using standard reflow profiles; no electrical connection is required or recommended, and it is not internally tied to GND or any other pin.
How does the NX3V1T384GM,115 achieve −90 dB OFF-isolation at 100 kHz?
The NX3V1T384GM,115 achieves −90 dB OFF-isolation at 100 kHz through optimized CMOS transistor sizing, guard-ring layout, and low parasitic capacitance (CS(OFF) = 70 pF). This performance is measured per Figure 19 in the datasheet with RL = 50 Ω and confirms effective signal blocking between Y and Z when the switch is disabled - critical for noise-sensitive audio and RF-adjacent circuits.
