Product details
Overview
NX3L1T3157GMZ from NXP Semiconductors is a low-ohmic SPDT analog switch configured as a 2:1 multiplexer/demultiplexer, featuring 0.5 Ω typical ON resistance at 4.3 V supply, break-before-make switching, and Schmitt-trigger digital input for noise immunity. It operates across 1.4 V to 4.3 V supply, supports 1.8 V logic control at 3.6 V VCC, and handles ±350 mA continuous switch current - enabling signal routing in portable audio and data interface paths.
For engineers reviewing the NX3L1T3157GMZ datasheet, NX3L1T3157GMZ pinout, NX3L1T3157GMZ application, or NX3L1T3157GMZ equivalent, key selection criteria include its ultra-low RON flatness (0.13 Ω), −40 °C to +125 °C extended temperature rating, ESD robustness (8 kV IEC61000-4-2 contact), and compatibility with mixed-voltage system-level signal switching without level translation.
Technical Context
The NX3L1T3157GMZ implements CMOS transmission-gate architecture with integrated Schmitt-trigger on the S select input, ensuring clean switching even with slow-rising control signals. Its bidirectional analog path supports voltage rail-to-rail signal transmission (0 V to VCC) between Z and either Y0 or Y1, with guaranteed break-before-make timing down to 2 ns at 4.3 V.
Dynamic performance includes 22 ns typical enable time and 10 ns disable time at 3.6–4.3 V, −3 dB bandwidth exceeding 60 MHz, and isolation >90 dB at 100 kHz in OFF state. Charge injection is tightly controlled (≤15 pC at 4.3 V), minimizing glitch-induced errors in precision sampling paths.
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 4.3 V systems without external regulators. |
| Typical ON Resistance | 0.50 Ω at VCC = 4.3 V - minimizes insertion loss and signal distortion in high-fidelity audio and sensor signal paths. |
| RON Flatness | 0.13 Ω at VCC = 2.7 V - ensures consistent gain and linearity across full analog input swing, critical for ADC front-end switching. |
| Switch Current Rating | ±350 mA continuous - supports driving moderate-load peripherals like audio codecs or display interface lines. |
| ESD Robustness | 8 kV IEC61000-4-2 contact discharge on switch ports - eliminates need for external TVS diodes in handheld device I/O protection schemes. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood and industrial edge-node environments where thermal margin is constrained. |
| Enable/Disable Time | 22 ns / 10 ns typical at VCC ≥ 3.6 V - enables high-speed channel selection in real-time data acquisition and TDM 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 analog I/O | One of two selectable signal paths; bidirectional, supports rail-to-rail voltage up to VCC. |
| 2 (GND) | Ground reference | Primary return path for supply and signal currents; must be low-impedance for THD < 0.02 %. |
| 3 (Y0) | Independent analog I/O | Second selectable signal path; electrically matched to Y1 for ≤0.075 Ω RON mismatch at 4.3 V. |
| 4 (Z) | Common analog I/O | Shared port connecting to Y0/Y1; carries full switch current (±350 mA); requires local decoupling. |
| 5 (VCC) | Power supply | Supplies internal logic and analog switches; accepts 1.4–4.3 V; bypass capacitor mandatory for dynamic stability. |
| 6 (S) | Digital select input | Schmitt-triggered control line; accepts 0–4.3 V inputs; enables 1.8 V logic drive at 3.6 V VCC without level shifters. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum analog signal voltage the NX3L1T3157GMZ can switch?
The NX3L1T3157GMZ supports analog signals from 0 V to VCC. With a maximum supply voltage of 4.3 V, it can reliably switch signals up to 4.3 V peak-to-peak without clipping or distortion - enabling direct connection to 3.3 V and 4.3 V DAC outputs, audio amplifiers, and sensor interfaces without external clamping or attenuation networks. This rail-to-rail capability is confirmed across the full −40 °C to +125 °C operating range.
Does the NX3L1T3157GMZ require external level-shifting when driven by a 1.8 V microcontroller?
No, the NX3L1T3157GMZ does not require external level-shifting when driven by a 1.8 V microcontroller. Its Schmitt-trigger input accepts VIH as low as 0.9 V (at VCC = 1.4–1.6 V) and up to 1.4 V (at VCC = 3.6–4.3 V), and its input threshold remains valid across the full 1.4–4.3 V supply range. At VCC = 3.6 V, a 1.8 V logic HIGH is sufficient to guarantee reliable switching - eliminating translation circuitry and reducing BOM count.
What is the guaranteed break-before-make timing for the NX3L1T3157GMZ?
The NX3L1T3157GMZ guarantees break-before-make timing by design, with measured values as low as 2 ns at VCC = 3.6–4.3 V. This ensures no overlap between Y0 and Y1 conduction paths during switching transitions, preventing momentary shorts in applications such as dual-source audio mixing or redundant sensor selection. The specification is validated across −40 °C to +125 °C and is independent of load capacitance or signal amplitude.
How does the NX3L1T3157GMZ perform in terms of audio signal integrity?
The NX3L1T3157GMZ delivers high-fidelity audio performance with total harmonic distortion (THD) as low as 0.02 % at 2 Vp-p input and 4.3 V supply, and a −3 dB bandwidth exceeding 60 MHz. Its 0.13 Ω RON flatness preserves signal linearity, while 15 pC charge injection minimizes transient glitches at channel transitions - making it suitable for headphone output switching, microphone path selection, and codec interface routing in premium portable audio devices.
Is the NX3L1T3157GMZ suitable for industrial applications requiring extended temperature operation?
Yes, the NX3L1T3157GMZ is fully specified and qualified for operation from −40 °C to +125 °C, with all key parameters - including RON, leakage current, enable time, and ESD robustness - guaranteed across this full range. Its 8 kV IEC61000-4-2 contact ESD rating on switch ports further supports deployment in factory-floor environments subject to frequent human handling and electrostatic events, without requiring supplemental protection components.
