Product details
Overview
NX3L1T3157GM,115 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 supply, break-before-make switching, and 1.8 V logic-compatible control input enabling direct interfacing with low-voltage controllers while switching up to 4.3 V analog signals.
For engineers reviewing the NX3L1T3157GM,115 datasheet, NX3L1T3157GM,115 pinout, NX3L1T3157GM,115 application, or NX3L1T3157GM,115 equivalent, key selection criteria include its 1.4–4.3 V wide supply range, −40 °C to +125 °C operating temperature, ESD robustness (8 kV IEC61000-4-2), and XSON6 package footprint for space-constrained designs.
Technical Context
The NX3L1T3157GM,115 implements CMOS-based transmission gate architecture with Schmitt-triggered digital select input (S), ensuring noise immunity against slow-rising/falling control edges. Its bidirectional signal path supports Z ↔ Y0/Y1 operation with voltage swing up to VCC on all ports.
Break-before-make timing is guaranteed by design (min 2 ns at 4.3 V), preventing momentary shorting during channel switching. Charge injection is tightly controlled (≤15 pC at 4.3 V), minimizing transient glitches in precision analog paths such as audio or sensor interfaces.
Key Specifications

| Logic Input Compatibility | 1.8 V control logic at VCC = 3.6 V - eliminates need for external voltage translation when driven by low-VDD microcontrollers |
| ESD Protection | 8 kV IEC61000-4-2 contact discharge on switch ports - ensures robustness in handheld device assembly and end-user handling |
| Operating Temperature | −40 °C to +125 °C - qualified for extended industrial and automotive cabin applications requiring thermal resilience |
| Switch Current Rating | ±350 mA continuous - supports high-current analog paths including speaker drivers or power rail switching |
| Enable/Disable Time | 22 ns typical enable time at VCC = 3.6–4.3 V - suitable for fast-switching applications like USB port detection or dynamic signal routing |
Pinout & Package
XSON6 (SOT886) package: plastic extremely thin small outline, no leads, 6 terminals, body size 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 | One of two selectable signal paths; bidirectional, rated for full VCC swing |
| 2 (GND) | Ground reference | Primary return path for supply and signal currents; must be low-impedance for noise control |
| 3 (Y0) | Independent input/output | Second selectable signal path; electrically isolated from Y1 when OFF |
| 4 (Z) | Common input/output | Shared terminal connecting to either Y0 or Y1 based on S state; handles bidirectional analog/digital signals |
| 5 (VCC) | Positive supply | Power rail defining maximum signal voltage range; also powers internal logic and switch transistors |
| 6 (S) | Select input | Digital control line with Schmitt trigger; accepts 0–4.3 V logic levels independent of VCC |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed minimum 2 ns dead time at 4.3 V - prevents cross-conduction and signal shorting during channel transitions |
| Low ON-resistance flatness | 0.13 Ω typical at 2.7 V - ensures consistent signal gain/loss across input voltage range for high-fidelity audio routing |
| High OFF-state isolation | −90 dB at 100 kHz - suppresses crosstalk between inactive channels in multi-source audio or sensor multiplexing |
| Ultra-low charge injection | 15 pC max at 4.3 V - minimizes voltage step artifacts at Z node during switching, critical for precision ADC front-ends |
| Wide logic input voltage tolerance | Accepts inputs up to VCC + 0.5 V - allows direct connection to higher-voltage GPIOs without clamping diodes or resistors |

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-bit bidirectional level shifter with auto-direction sensing; not a true analog switch - lacks RON spec, no VCC-referenced signal swing | Designed for I²C/SPI bus translation, not analog signal routing; unsuitable for audio or sensor multiplexing | Choose only for digital bus interface; avoid for analog path switching due to undefined analog performance |
| TMUX1574RSVR | 4-channel SPDT with 0.5 Ω RON at 3.3 V, but requires ≥1.8 V logic and has higher 12 pC charge injection at 3.3 V | Same functional role but larger 16-pin UQFN package; better for multi-channel systems needing integrated enable control | Prefer for designs requiring >1 SPDT channel or integrated enable; NX3L1T3157GM,115 remains optimal for ultra-compact single-channel use |
Compared with TXS0102DCUR and TMUX1574RSVR, the NX3L1T3157GM,115 delivers superior analog fidelity (0.13 Ω flatness, −90 dB isolation), smallest footprint (XSON6), and widest supply range - making it the preferred choice for space- and performance-critical analog multiplexing where true analog signal integrity is mandatory.

FAQ
What is the maximum analog signal voltage the NX3L1T3157GM,115 can switch?
The NX3L1T3157GM,115 supports analog signal voltages from GND to VCC on all ports (Z, Y0, Y1). With VCC up to 4.3 V, it can reliably switch signals up to 4.3 V peak-to-peak. The absolute maximum switch voltage is VCC + 0.5 V per limiting values, but operation beyond VCC is not recommended for signal integrity or reliability. The NX3L1T3157GM,115 datasheet specifies VSW ≤ VCC under recommended conditions.
Does the NX3L1T3157GM,115 require external pull-up or pull-down resistors on the S pin?
No. The NX3L1T3157GM,115 incorporates a Schmitt-trigger input on the S pin, providing hysteresis and eliminating the need for external biasing resistors. It accepts logic levels from 0 V to 4.3 V regardless of VCC, and VIH/VIL thresholds scale with supply voltage (e.g., VIH = 1.4 V min at VCC = 4.3 V). This simplifies interface design with diverse microcontrollers and eliminates BOM overhead. The NX3L1T3157GM,115 operates reliably with direct GPIO connection.
Can the NX3L1T3157GM,115 be used in automotive cabin applications?
Yes. The NX3L1T3157GM,115 is specified for operation from −40 °C to +125 °C and meets IEC61000-4-2 Level 4 ESD (8 kV contact) on switch ports - characteristics aligned with automotive cabin ambient requirements. While not AEC-Q200 qualified, its extended temperature rating and robust ESD performance make it suitable for non-safety-critical cabin electronics such as infotainment audio routing or climate sensor multiplexing. Always verify system-level qualification per OEM requirements.
How does the NX3L1T3157GM,115 achieve 1.8 V logic compatibility while operating at 3.3 V or 4.3 V supply?
The NX3L1T3157GM,115 uses an internally regulated input buffer that decouples logic threshold levels from VCC. At VCC = 3.6 V, VIH is specified at 1.3 V min and VIL at 0.5 V max - well within 1.8 V logic swing margins. This allows direct connection to 1.8 V GPIOs without level shifters, reducing power consumption and board area. The NX3L1T3157GM,115 achieves this via process-tuned threshold devices, not external circuitry.
What is the thermal derating behavior of the NX3L1T3157GM,115 above 118 °C?
Above 118 °C, the NX3L1T3157GM,115 total power dissipation (Ptot) derates linearly at 7.8 mW/K, per the datasheet limiting values table. At 125 °C, Ptot is reduced to approximately 197 mW from the 250 mW maximum at ≤118 °C. This derating ensures safe junction temperature operation under sustained high-temperature conditions. Designers must calculate worst-case power (I²×RON + ICC×VCC) and apply this slope to maintain TJ < 150 °C.
