Product details
Overview
NX3L1T3157GW,125 from NXP Semiconductors is a low-ohmic single-pole double-throw (SPDT) analog switch configured as a 2:1 multiplexer/demultiplexer, with digital select input (S), two independent I/Os (Y0, Y1), and a common I/O (Z). It operates from 1.4 V to 4.3 V supply, delivers 0.5 Ω typical ON resistance at 4.3 V, supports 1.8 V logic control in 3.3 V systems, and handles ±350 mA continuous switch current - enabling high-fidelity audio routing in portable media players.
For engineers reviewing the NX3L1T3157GW,125 datasheet, NX3L1T3157GW,125 pinout, NX3L1T3157GW,125 application, or NX3L1T3157GW,125 equivalent, this page provides verified functional specifications, XSON6 package details, break-before-make timing data, ESD robustness (8 kV IEC61000-4-2), and real-world use context for signal path selection in battery-powered consumer electronics.
Technical Context
The NX3L1T3157GW,125 implements CMOS-based transmission gate architecture with Schmitt-triggered digital input for noise immunity and slow-edge tolerance. Its bidirectional analog path supports signal amplitudes up to VCC in either direction (Z ↔ Y0/Y1), with guaranteed break-before-make switching to prevent channel shorting during state transitions.
It features rail-to-rail analog signal handling, 1.8 V logic-compatible control input that accepts voltages above VCC, and ultra-low supply current (≤150 nA at 4.3 V) even under sub-VCC input conditions - making it suitable for always-on signal routing in power-constrained mobile devices operating across −40 °C to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 4.3 V - enables direct integration into 1.8 V, 2.5 V, 3.3 V, and 4.2 V battery-powered systems without level shifters. |
| ON Resistance (Typ) | 0.50 Ω at VCC = 4.3 V - minimizes insertion loss and voltage drop in high-current analog paths (e.g., headphone drivers). |
| ON Resistance Flatness | 0.13 Ω at VCC = 2.7 V - ensures consistent signal amplitude across full input voltage swing, critical for audio fidelity. |
| Switch Current Rating | ±350 mA continuous - supports driving low-impedance loads such as 16 Ω speakers or RF front-end switches. |
| ESD Robustness | 8 kV IEC61000-4-2 contact discharge on switch ports - eliminates need for external TVS diodes in handheld device interfaces. |
| Enable/Disable Time | 22 ns / 10 ns typical at VCC = 3.6 V - enables fast channel reconfiguration in time-sensitive applications like USB-C alternate mode switching. |
| Operating Temperature | −40 °C to +125 °C - qualified for extended thermal environments in automotive infotainment and industrial portable equipment. |
Pinout & Package
XSON6 (SOT886) plastic extremely thin small outline package; no leads; 6 terminals; body dimensions 1.0 × 1.45 × 0.5 mm; pin 1 indicator located on lower left corner below marking code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Y1) | Independent input/output | First analog channel endpoint; bidirectional signal path selectable via S input. |
| 2 (GND) | Ground reference | Primary return path for supply and signal currents; must be low-impedance for THD < 0.02 %. |
| 3 (Y0) | Independent input/output | Second analog channel endpoint; electrically isolated from Y1 when OFF. |
| 4 (Z) | Common input/output | Shared signal node; connects to Y0 or Y1 based on S logic state; supports rail-to-rail voltage swing. |
| 5 (VCC) | Supply voltage | Power rail for analog and digital circuitry; also defines maximum switch voltage (VSW ≤ VCC). |
| 6 (S) | Select input | Digital control line with Schmitt trigger; accepts 1.8 V logic levels at 3.3 V VCC without level translation. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed by design (tb-m ≤ 10 ns at VCC ≥ 2.7 V); prevents momentary short between Y0 and Y1 during transition. |
| Rail-to-rail analog signal handling | Supports signals from GND to VCC on all ports (Z, Y0, Y1); enables full dynamic range usage in audio and sensor interfaces. |
| 1.8 V logic-compatible control | VIH = 1.3 V max at VCC = 3.6 V; allows direct interface with low-voltage microcontrollers without pull-up resistors or translators. |
| Ultra-low charge injection | 9 pC typical at VCC = 3.3 V; reduces glitch-induced DC offset in precision ADC/DAC multiplexing applications. |
| High OFF-state isolation | −90 dB at 100 kHz; suppresses crosstalk between active and inactive channels in multi-source audio routing. |

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 translator (not analog switch); no rail-to-rail analog pass-through; 5 V tolerant I/O but no Z-Y0/Y1 topology. | Designed for digital signal translation only; unsuitable for analog audio or sensor multiplexing requiring continuous voltage domain bridging. | Choose only if digital-level shifting (e.g., I²C bus extension) is required - not for analog signal routing. |
| TMUX1574RSVR | SPDT analog switch with 0.7 Ω typical RON at 3.3 V; wider −40 °C to +125 °C range; no integrated Schmitt trigger on control input. | Higher RON increases insertion loss in low-voltage audio paths; lacks built-in noise immunity for noisy PCB environments. | Acceptable where Schmitt triggering is provided externally and 0.2 Ω higher RON is tolerable in system SNR budget. |
Compared with TXS0102DCUR and TMUX1574RSVR, the NX3L1T3157GW,125 uniquely combines true analog bidirectionality, sub-0.5 Ω RON at 4.3 V, Schmitt-triggered control, and 8 kV ESD-hardened switch ports - making it optimal for compact, high-fidelity, low-power consumer audio routing where signal integrity and layout simplicity are critical.

FAQ
What is the maximum analog signal voltage the NX3L1T3157GW,125 can switch?
The NX3L1T3157GW,125 supports analog signal voltages from GND to VCC on all ports (Z, Y0, Y1). With a maximum recommended supply of 4.3 V, it can reliably switch signals up to 4.3 V peak-to-peak in either direction. Exceeding VCC risks violating the absolute maximum switch voltage rating of VCC + 0.5 V, potentially causing latch-up or permanent damage. Always maintain VSW ≤ VCC for guaranteed operation.
Does the NX3L1T3157GW,125 require external level-shifting when controlled by a 1.8 V microcontroller in a 3.3 V system?
No, the NX3L1T3157GW,125 does not require external level-shifting. Its digital select input (S) has a VIH threshold of 1.3 V maximum at VCC = 3.6 V, fully compatible with standard 1.8 V logic HIGH levels. This feature eliminates external translators and simplifies PCB layout - a key advantage confirmed in the device's functional description and Table 7 static characteristics.
Is the NX3L1T3157GW,125 pin-compatible with other members of the NX3L family?
The NX3L1T3157GW,125 uses the XSON6 (SOT886) package with fixed 6-pin configuration (Y1-GND-Y0-Z-VCC-S). While other NX3L devices like NX3L2T3157 share identical pinout and package, the NX3L1T3157GW,125 is a single-pole double-throw variant - distinct from dual-channel or SPST versions. Pin compatibility holds only for same-function, same-package variants; cross-referencing requires verifying both topology and pin assignment per datasheet.
What is the thermal performance limit of the NX3L1T3157GW,125 in its XSON6 package?
In the XSON6 package, the NX3L1T3157GW,125 has a total power dissipation limit of 250 mW at ambient temperatures from −40 °C to +125 °C. Above 118 °C, Ptot derates linearly at 7.8 mW/K. At maximum rated switch current (±350 mA) and worst-case RON (0.9 Ω), power dissipation reaches ~110 mW - well within safe operating limits under typical conditions, provided PCB copper area meets recommended thermal pad guidelines.
How does the NX3L1T3157GW,125 achieve high noise immunity on its digital input?
The NX3L1T3157GW,125 achieves high noise immunity through an integrated Schmitt trigger on the S input, providing hysteresis of approximately 0.4 V to 0.6 V depending on VCC. This design rejects slow-rising/falling edges and transient noise on control lines - a documented feature explicitly cited in the General Description section and validated in the VIH/VIL specifications across all supply voltages.
