NXP Semiconductors NX3L1G3157GM,115

Overview

NX3L1G3157GM,115 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, delivering 0.50 Ω typical ON resistance at 2.7 V and 4.3 V, with break-before-make switching and −40 °C to +125 °C temperature range - used in portable audio signal routing in smartphones and media players.

For engineers reviewing the NX3L1G3157GM,115 datasheet, NX3L1G3157GM,115 pinout, NX3L1G3157GM,115 application, or NX3L1G3157GM,115 equivalent, key selection criteria include ON resistance flatness (0.13 Ω), charge injection (≤15 pC at 4.3 V), isolation (−90 dB at 100 kHz), THD (0.02% at 2.7 V/2 V_p-p), and ESD robustness (8 kV IEC61000-4-2 contact).

Technical Context

The NX3L1G3157GM,115 implements CMOS-based transmission gate architecture with Schmitt-trigger input on the digital select line (S), enabling tolerance to slow input edges. Its bidirectional signal path supports voltage swing up to V_CC between Z and Y0/Y1 terminals without level-shifting.

It guarantees break-before-make timing (≤10 ns at V_CC ≥ 2.7 V), features 350 mA continuous switch current capability, and maintains <±500 nA leakage across −40 °C to +125 °C - critical for low-noise audio and precision analog multiplexing where channel crosstalk and signal integrity are design-critical.

FAQ

What is the maximum continuous current rating for the NX3L1G3157GM,115?

The NX3L1G3157GM,115 supports 350 mA continuous current under 3.3 V supply conditions, as specified in Table 5 of the datasheet. This rating applies to bidirectional conduction between Z and either Y0 or Y1 terminals, with derating above +118 °C per the thermal characteristics of the XSON6 package.

Does the NX3L1G3157GM,115 support operation below 1.65 V supply?

Yes, the NX3L1G3157GM,115 is fully specified from 1.4 V to 4.3 V supply voltage, including ON resistance (1.6 Ω typical at 1.4 V), enable time (43 ns max), and logic thresholds. This makes the NX3L1G3157GM,115 suitable for direct connection to deeply discharged Li-ion batteries or low-voltage microcontroller I/O domains.

Is break-before-make timing guaranteed for the NX3L1G3157GM,115?

Yes, break-before-make timing is guaranteed by design per Table 9 footnote [2], with measured values of ≤10 ns at V_CC ≥ 2.7 V. This eliminates risk of momentary short-circuit between Y0 and Y1 during channel switching - a critical requirement in audio and sensor multiplexing applications.

What is the charge injection specification for the NX3L1G3157GM,115 at 3.3 V?

At V_CC = 3.3 V, the NX3L1G3157GM,115 exhibits 9 pC typical charge injection, as listed in Table 12. This low value minimizes transient voltage spikes at high-impedance nodes such as ADC input capacitors or op-amp summing junctions, preserving DC accuracy in precision measurement circuits.

How does the NX3L1G3157GM,115 handle input voltages exceeding V_CC on the S pin?

The NX3L1G3157GM,115 allows control input voltages up to 4.6 V on the S pin regardless of V_CC, as defined in Table 5 (VI max = +4.6 V). This enables direct interfacing with 3.3 V or 5 V logic controllers without level-shifting circuitry - a feature explicitly confirmed in the "Features and benefits" section of the datasheet.
