Product details
Overview
NX3L1T3157GM,132 from NXP Semiconductors is a low-ohmic single-pole double-throw (SPDT) analog switch configured as a 2:1 multiplexer/demultiplexer, operating across 1.4 V to 4.3 V supply. It features 0.50 Ω typical ON resistance at 4.3 V, break-before-make switching, and Schmitt-trigger digital input for noise immunity. It enables 4.3 V analog signal routing under 1.8 V logic control in portable audio and interface applications.
For engineers reviewing the NX3L1T3157GM,132 datasheet, NX3L1T3157GM,132 pinout, NX3L1T3157GM,132 application, or NX3L1T3157GM,132 equivalent, key selection criteria include ON resistance flatness (0.13 Ω), −40 °C to +125 °C operation, 350 mA continuous current handling, ESD robustness (8 kV IEC61000-4-2), and compatibility with 1.8 V control in 3.3 V systems without level translation.
Technical Context
The NX3L1T3157GM,132 implements CMOS transmission-gate architecture with Schmitt-trigger input on the select line (S), enabling reliable switching despite slow digital edge rates. Its bidirectional signal path supports Z ↔ Y0/Y1 routing with voltage swing up to VCC on all ports.
Break-before-make timing is guaranteed by design (minimum 2 ns at 4.3 V), preventing momentary shorting between Y0 and Y1. The device maintains low charge injection (15 pC max at 4.3 V) and high OFF-state isolation (−90 dB at 100 kHz), critical for precision analog multiplexing in audio and sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
XSON6 (SOT886) package: plastic extremely thin small outline, no leads, 6 terminals, body size 1.0 mm × 1.45 mm × 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Y1 | Independent input/output | One of two selectable signal paths; bidirectional, supports rail-to-rail analog signals up to VCC. |
| 2 - GND | Ground reference | Primary return path for supply and signal currents; must be low-impedance for THD and crosstalk performance. |
| 3 - Y0 | Independent input/output | Second selectable signal path; electrically matched to Y1 for <0.1 Ω RON mismatch across temperature. |
| 4 - Z | Common input/output | Shared port connecting to either Y0 or Y1; handles full VCC-swing signals in both directions with <500 nA leakage. |
| 5 - VCC | Positive supply | Power rail defining analog signal range and logic threshold; accepts 1.4–4.3 V with <7 μA ΔICC at 1.8 V control. |
| 6 - S | Select input | Digital control line with Schmitt trigger; accepts 0–4.3 V logic levels independent of VCC, enabling 1.8 V MCU control of 4.3 V analog paths. |
Key Features
| Feature | Design Value |
|---|---|
| 1.8 V logic-compatible control | Accepts 1.8 V input at VCC = 3.6 V without level shifters - reduces BOM count and PCB area in mixed-voltage portable designs. |

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 with auto-direction sensing; not a true analog switch - lacks RON <1 Ω or rail-to-rail analog passband. | Designed for digital I²C/GPIO translation only; unsuitable for analog audio or sensor signals due to limited bandwidth and nonlinear transfer. | Select only when translating digital control signals - not for analog signal routing where NX3L1T3157GM,132's 60 MHz f(−3dB) and <0.02 % THD are required. |
| TMUX1574RSVR | SPDT analog switch with 0.5 Ω RON (typ), but rated only to +85 °C and requires minimum 1.08 V logic - no Schmitt trigger or 1.8 V logic support at 3.3 V VCC. | Lacks guaranteed break-before-make and fails to meet 125 °C industrial requirement; lower ESD rating (4 kV HBM vs. 8 kV IEC). | Use only in commercial-temperature consumer devices where 1.8 V control at 3.3 V VCC is not needed and thermal margin is sufficient. |
Compared with TXS0102DCUR and TMUX1574RSVR, the NX3L1T3157GM,132 uniquely combines 1.8 V logic compatibility at 3.3 V VCC, −40 °C to +125 °C operation, and 0.50 Ω RON with guaranteed break-before-make - making it the sole option for robust, mixed-voltage analog multiplexing in portable industrial and automotive-adjacent systems.

FAQ
What is the maximum analog signal voltage the NX3L1T3157GM,132 can switch?
The NX3L1T3157GM,132 supports analog signals from 0 V 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. Exceeding VCC risks violating the absolute maximum switch voltage rating of VCC + 0.5 V, potentially causing latch-up or permanent damage. The NX3L1T3157GM,132 must never be used with analog signals exceeding its supply rail.
Can the NX3L1T3157GM,132 be controlled directly by a 1.8 V microcontroller when VCC is 3.3 V?
Yes. The NX3L1T3157GM,132 features a Schmitt-trigger input on the S pin that accepts 1.8 V logic levels even when VCC = 3.3 V or 3.6 V, with no increase in supply current. This eliminates the need for external level translators. The NX3L1T3157GM,132 VIH is 1.3 V (min) at VCC = 2.7–3.6 V, ensuring reliable HIGH detection from 1.8 V GPIOs.
Does the NX3L1T3157GM,132 support bidirectional signal flow?
Yes. The NX3L1T3157GM,132 is fully bidirectional: signals may pass from Z to Y0/Y1 or from Y0/Y1 to Z with identical ON resistance, capacitance, and leakage characteristics. This enables flexible use as a mux or demux in analog signal paths such as audio routing or sensor readout. The NX3L1T3157GM,132 does not impose directionality constraints on analog signal flow.
What is the thermal performance limit of the NX3L1T3157GM,132 in the XSON6 package?
The NX3L1T3157GM,132 in XSON6 (SOT886) has a total power dissipation limit of 250 mW at Tamb = −40 °C to +125 °C. Above 118 °C, Ptot derates linearly at 7.8 mW/K. At maximum ambient temperature (125 °C), usable power is reduced to ~200 mW. Thermal design must ensure junction temperature stays below 150 °C under worst-case load conditions. The NX3L1T3157GM,132's low RON minimizes self-heating during 350 mA operation.
How does the NX3L1T3157GM,132 achieve high noise immunity on its digital input?
The NX3L1T3157GM,132 integrates a Schmitt-trigger buffer on the S pin, providing hysteresis of approximately 0.4 V at VCC = 3.3 V. This rejects noise spikes and accommodates slow rise/fall times (up to 200 ns/V transition rate) without false triggering. The NX3L1T3157GM,132's input threshold is defined by VIH/VIL specifications, not VCC/2, ensuring robust operation in electrically noisy portable environments.
