Product details
Overview
NX3L4684GM,132 from NXP Semiconductors is a dual low-ohmic SPDT analog switch optimized for signal routing in portable audio and data interfaces. It features 0.3 Ω typical ON resistance (Y0 port at VCC = 2.3 V), break-before-make switching, and 1.4 V to 4.3 V supply operation - enabling 4.3 V analog signal switching with 1.8 V digital control without level translation. It supports bidirectional signal transmission across two independent channels in consumer handheld devices.
For engineers reviewing the NX3L4684GM,132 datasheet, NX3L4684GM,132 pinout, NX3L4684GM,132 application, or NX3L4684GM,132 equivalent, key selection criteria include its ultra-low RON flatness (0.1 Ω), −40 °C to +125 °C temperature rating, ESD robustness (6 kV IEC61000-4-2 contact), and XQFN10 package compatibility with high-density PCB layouts.
Technical Context
The NX3L4684GM,132 implements a CMOS-based dual SPDT architecture with Schmitt-trigger digital inputs for noise immunity and tolerance to slow edge rates. Each channel operates independently with dedicated select (nS), common (nZ), and dual path (nY0/nY1) terminals, supporting bidirectional analog/digital signal routing up to VCC amplitude.
Its break-before-make timing (as low as 1 ns at VCC = 4.3 V) prevents signal shorting during state transitions, while charge injection (10–50 pC across VCC range) and crosstalk (−90 dB) are tightly controlled for audio-grade fidelity. The device maintains stable RON over full temperature and voltage ranges due to matched transistor design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 4.3 V - enables single-supply operation across Li-ion battery voltages and logic domains. |
| ON Resistance (Y0) | 0.3 Ω typical at VCC = 2.3 V - minimizes insertion loss and signal distortion in audio/data paths. |
| ON Resistance Flatness (Y0) | 0.1 Ω - ensures consistent gain/attenuation across input voltage swing, critical for linearity-sensitive applications. |
| Switch Bandwidth | 15 MHz (Y0 port) - supports high-fidelity audio and medium-speed digital signal routing (e.g., USB 1.1, I²C). |
| ESD Rating | 6 kV IEC61000-4-2 contact discharge on switch ports - eliminates need for external protection in handheld front-end designs. |
| Operating Temperature | −40 °C to +125 °C - qualified for automotive infotainment and industrial portable equipment environments. |

Pinout & Package
XQFN10 (SOT1049-3) package: plastic extremely thin quad flat package, no leads, 2.0 × 1.55 × 0.5 mm body, exposed thermal pad (not electrically connected), moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1Y0 | Independent analog I/O for Channel 1 - connects to source/sink of first signal path (e.g., left audio channel). |
| 2 | 1S | Channel 1 select input - Schmitt-triggered; accepts 1.8 V logic even at 3.6 V VCC without level shifters. |
| 3 | 1Z | Common analog I/O for Channel 1 - bidirectional node shared between 1Y0 and 1Y1; routes signal to/from system bus. |
| 4 | 1Y1 | Independent analog I/O for Channel 1 - alternate path for multiplexing (e.g., right audio or auxiliary input). |
| 5 | VCC | Positive supply - powers internal circuitry and defines maximum analog signal swing (up to VCC). |
| 6 | 2Y1 | Independent analog I/O for Channel 2 - isolated second switch path for stereo, dual-data, or redundancy routing. |
| 7 | 2Z | Common analog I/O for Channel 2 - independent bidirectional node; enables simultaneous dual-channel operation. |
| 8 | 2S | Channel 2 select input - electrically identical to 1S; allows independent control of both switches. |
| 9 | 2Y0 | Independent analog I/O for Channel 2 - complements 2Y1 for full dual SPDT functionality. |
| 10 | GND | Ground reference - return path for supply current and signal common; must be low-impedance for THD < 0.02 %. |
Key Features
| Feature | Design Value |
|---|---|
| 1.8 V logic-compatible control | Operates with 1.8 V digital inputs at VCC = 3.6 V - eliminates level translators in mixed-voltage SoC interfaces. |
| Break-before-make switching | Guaranteed >1 ns isolation gap prevents momentary short-circuit between nY0/nY1 during channel change. |
| Ultra-low charge injection | 10–50 pC across VCC range - reduces glitch-induced pop/click in audio output stages and ADC front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.

FAQ
What is the maximum analog signal voltage the NX3L4684GM,132 can switch?
The NX3L4684GM,132 supports analog signal amplitudes up to VCC on all switch terminals (nY0, nY1, nZ). With a maximum rated supply voltage of 4.3 V, it can reliably pass signals from 0 V to 4.3 V in either direction. This capability allows direct interfacing with 3.3 V or 4.2 V Li-ion battery rails without clamping or attenuation, provided switch voltage remains within VCC + 0.5 V absolute maximum rating.
Does the NX3L4684GM,132 require external pull-up or pull-down resistors on its select inputs?
No, the NX3L4684GM,132 does not require external pull-up or pull-down resistors on its 1S and 2S inputs. Its Schmitt-trigger inputs provide hysteresis and defined logic thresholds (VIH = 1.3 V min at VCC = 3.6 V; VIL = 0.5 V max), ensuring clean switching even with slow-rising control signals. Internal input leakage is limited to ±1 µA, so direct connection to GPIOs or logic gates is sufficient.
Can the NX3L4684GM,132 be used in audio line-level applications with low THD requirements?
Yes, the NX3L4684GM,132 achieves total harmonic distortion as low as 0.01 % at 3.0 V VCC with 1 Vp-p input into 600 Ω load - meeting line-level audio fidelity requirements. Its ultra-low RON flatness (0.1 Ω), low charge injection (14 pC at 1.8 V), and −90 dB isolation minimize distortion, pop/click artifacts, and crosstalk, making it suitable for headphone amplifiers, DAC outputs, and microphone preamp routing.
Is the NX3L4684GM,132 pin-compatible with other variants in the NX3L4684 family?
Yes, the NX3L4684GM,132 shares identical pinout and footprint with the NX3L4684TK (HVSON10 package), as confirmed in Table 3 of the datasheet. Both use the same SOT1049-3 and SOT650-2 pin mappings for 1Y0, 1S, 1Z, 1Y1, VCC, 2Y1, 2Z, 2S, 2Y0, and GND. This allows direct PCB substitution between XQFN10 and HVSON10 packages without layout changes.
What is the thermal performance of the NX3L4684GM,132 in its XQFN10 package?
The NX3L4684GM,132 in XQFN10 (SOT1049-3) has a thermal derating slope of 14.1 mW/K above 132 °C ambient, with a maximum total power dissipation of 250 mW at 125 °C. Its 0.5 mm profile and exposed thermal pad (though unconnected per datasheet) enable efficient heat spreading in compact handheld PCBs. Junction-to-ambient thermal resistance is approximately 400 K/W, supporting continuous 350 mA switch current at rated temperatures.
