Product details
Overview
NX3L1T5157GMAZ from NXP Semiconductors is a low-ohmic single-pole double-throw (SPDT) analog switch optimized for 2:1 multiplexer/demultiplexer functions in portable electronics. It features 0.5 Ω typical ON resistance at 4.3 V, break-before-make switching, and operates across 1.4 V to 4.3 V supply with −40 °C to +125 °C temperature range. It enables 1.8 V logic control of up to 4.3 V analog signals without level translation in audio routing and sensor interface applications.
For engineers reviewing the NX3L1T5157GMAZ datasheet, NX3L1T5157GMAZ pinout, NX3L1T5157GMAZ application, or NX3L1T5157GMAZ equivalent, this page delivers verified electrical specs, thermal limits, dynamic timing, ESD robustness, and real-world use cases - all validated against NXP's Rev. 9.2 product data sheet dated 11 December 2019.
Technical Context
The NX3L1T5157GMAZ implements CMOS-based transmission gate architecture with Schmitt-trigger digital input for noise immunity and tolerance to slow signal edges. Its control logic accepts voltages above VCC, enabling direct interfacing with higher-voltage controllers while maintaining sub-1 µA supply current at standby.
It supports bidirectional signal flow between common terminal Z and independent ports Y0/Y1, with guaranteed break-before-make timing (as low as 2 ns at 4.3 V) to prevent signal shorting during channel switching. All static and dynamic parameters - including ON resistance flatness (0.13 Ω), charge injection (15 pC max), and isolation (−90 dB) - are specified over full industrial temperature and supply voltage ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 4.3 V - Enables operation from single-cell Li-ion (3.0–3.7 V) or dual-cell alkaline (up to 3.2 V) without regulation; supports 1.8 V/3.3 V mixed-signal systems. |
| ON Resistance (Typ) | 0.50 Ω at VCC = 4.3 V - Minimizes insertion loss and distortion in audio paths; maintains <0.1% attenuation for 100 mVpp signals at 350 mA load. |
| Enable/Disable Time | 22 ns / 10 ns (typ) at VCC = 4.3 V - Supports high-speed signal routing in USB 2.0 data switching and fast ADC/DAC channel selection. |
| ESD Robustness | ±8000 V IEC61000-4-2 contact discharge on switch ports - Eliminates need for external TVS diodes in handheld device front-end interfaces. |
| Operating Temperature | −40 °C to +125 °C - Qualified for extended-temperature industrial and automotive cabin applications without derating. |
| Switch Current Rating | ±350 mA continuous - Sustains full drive capability for headphone amplifiers, sensor excitation circuits, and GPIO multiplexing under worst-case thermal conditions. |

Pinout & Package
Package: XSON6 (SOT886), plastic extremely thin small outline package; no leads; 6 terminals; body dimensions 1.0 × 1.45 × 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Y1 | Independent analog I/O port | Connects to secondary signal source/sink (e.g., second microphone, auxiliary DAC output); bidirectional path when selected. |
| 2 - GND | Ground reference | Primary return path for supply and signal currents; must be low-inductance connection to minimize crosstalk and ground bounce. |
| 3 - Y0 | Independent analog I/O port | Connects to primary signal source/sink (e.g., main speaker driver, primary ADC input); active path when S = LOW. |
| 4 - Z | Common analog I/O terminal | Shared signal node routed to Y0 or Y1 based on select state; supports bidirectional signal flow up to VCC amplitude. |
| 5 - VCC | Positive supply rail | Power input for internal logic and analog switches; decoupling capacitor (100 nF) required within 2 mm for stable high-frequency performance. |
| 6 - S | Digital select input | CMOS-compatible control line with Schmitt trigger; accepts 1.8 V logic at 3.3 V VCC; tolerates overshoot up to VCC + 0.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed by design (min 2 ns dead time at 4.3 V) prevents momentary short between Y0 and Y1 during transition - critical for avoiding pop/click in audio paths. |
| 1.8 V logic compatibility at 3.6 V VCC | Enables direct interface with ultra-low-power microcontrollers (e.g., ARM Cortex-M0+) without level shifters - reduces BOM count and PCB area. |
| Low ON resistance flatness (0.13 Ω) | Ensures consistent signal gain/attenuation across full input voltage range (0–VCC), preserving linearity in sensor signal conditioning and audio routing. |
| High OFF-state isolation (−90 dB) | Suppresses crosstalk between inactive channels at 100 kHz - essential for multi-channel medical sensors and simultaneous sampling systems. |
| Ultra-low supply current (150 nA typ at 4.3 V) | Reduces quiescent power in always-on subsystems (e.g., wake-on-sensor, battery-backed RTC multiplexing) without compromising switching speed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DCUR | 2-channel bidirectional level shifter; no analog switching function; 5.5 V max VCC; 10 Ω typical RON | Designed for I²C/SPI voltage translation, not analog signal routing; lacks break-before-make and high-isolation specs | Select only if level shifting-not analog multiplexing-is required; not suitable for audio or sensor signal paths |
| MAX4617EUT+T | SPDT analog switch; 3.5 Ω typical RON at 5 V; −40 °C to +85 °C only; no 1.8 V logic support | Higher RON increases insertion loss; narrower temp range limits industrial use; requires 3.3 V logic interface | Acceptable for cost-sensitive consumer designs with relaxed performance; avoid where low distortion or extended temperature is mandatory |
Compared with TXS0102DCUR and MAX4617EUT+T, the NX3L1T5157GMAZ uniquely combines ultra-low RON (0.5 Ω), 1.8 V logic compatibility, −40 °C to +125 °C qualification, and −90 dB isolation - making it the only option qualified for precision, high-reliability analog routing in space-constrained portable systems.

FAQ
What is the maximum analog signal voltage the NX3L1T5157GMAZ can switch?
The NX3L1T5157GMAZ supports analog signal amplitudes up to VCC on all ports (Y0, Y1, Z). With a maximum rated VCC of 4.3 V, it can reliably switch signals from 0 V to 4.3 V in either direction. The absolute maximum switch voltage is VCC + 0.5 V (4.8 V), but operation beyond VCC is not recommended for sustained use. This capability allows the NX3L1T5157GMAZ to handle full-rail audio and sensor signals without clipping or distortion.
Does the NX3L1T5157GMAZ require external pull-up or pull-down resistors on the S pin?
No, the NX3L1T5157GMAZ integrates a Schmitt-trigger input on the S pin with defined VIH/VIL thresholds across all supply voltages (e.g., VIH = 1.4 V min at VCC = 4.3 V), eliminating the need for external biasing. The internal hysteresis ensures clean switching even with slow-rising control signals, and the input accepts voltages up to VCC + 0.5 V. This simplifies system design and reduces component count compared to standard CMOS switches requiring external resistors.
Can the NX3L1T5157GMAZ be used in automotive cabin applications?
Yes - the NX3L1T5157GMAZ is qualified for operation from −40 °C to +125 °C and meets stringent ESD requirements (±8000 V IEC61000-4-2 on switch ports), making it suitable for non-safety-critical automotive cabin applications such as infotainment audio routing, climate control sensor multiplexing, and interior lighting control. It is not AEC-Q100 automotive-qualified, so it should not be used in safety-critical or powertrain systems.
How does the NX3L1T5157GMAZ achieve 1.8 V logic compatibility while powered at 3.3 V?
The NX3L1T5157GMAZ uses a dedicated low-threshold input stage on the S pin that recognizes 1.8 V as a valid HIGH-level input even when VCC = 3.3 V or 4.3 V. Its VIH specification is 1.3 V min at VCC = 2.7–3.6 V and 1.4 V min at VCC = 3.6–4.3 V, ensuring reliable switching with 1.8 V microcontrollers without level translation. This feature is built into the silicon design and requires no external circuitry - a key differentiator of the NX3L1T5157GMAZ.
What is the thermal derating behavior of the NX3L1T5157GMAZ above 118 °C?
For the XSON6 package, total power dissipation (Ptot) derates linearly above 118 °C at 7.8 mW/K. At 125 °C ambient, Ptot is reduced from its 250 mW maximum (at ≤118 °C) to approximately 195 mW. This derating ensures safe operation under transient thermal conditions while maintaining functionality. Designers must calculate worst-case power (I² × RON + ICC × VCC) and verify junction temperature remains below 150 °C using the package's thermal resistance (RθJA ≈ 220 K/W).
