Product details
Overview
NX3L4684GM,115 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, VCC = 2.3 V), break-before-make switching, and 1.4–4.3 V supply operation - enabling 4.3 V analog signal switching with 1.8 V logic control without level translation. It supports bidirectional signal transmission between common (nZ) and independent ports (nY0/nY1) in consumer handheld devices.
For engineers reviewing the NX3L4684GM,115 datasheet, NX3L4684GM,115 pinout, NX3L4684GM,115 application, or NX3L4684GM,115 equivalent, key selection criteria include its ultra-low RON flatness (0.1 Ω), −40 °C to +125 °C automotive-grade temperature range, IEC61000-4-2 ESD robustness (6 kV contact), and XQFN10 package compatibility with high-density PCB layouts.
Technical Context
The NX3L4684GM,115 implements two independent CMOS SPDT switches with Schmitt-trigger digital inputs, ensuring noise immunity against slow-rising control signals. Each channel uses break-before-make architecture to prevent signal shorting during state transitions.
Its low-threshold logic interface accepts 1.8 V inputs at 3.6 V VCC while maintaining sub-1 μA ICC, and its bidirectional switch topology allows voltage translation-free routing of signals up to VCC across nZ ↔ nY0/nY1 paths - critical for USB, audio codec, and sensor multiplexing in battery-powered systems.

FAQ
What is the maximum analog signal voltage the NX3L4684GM,115 can switch?
The NX3L4684GM,115 supports analog signal voltages from 0 V to VCC across all switch paths (nZ ↔ nY0/nY1). With a maximum VCC of 4.3 V per datasheet limiting values, the device can reliably switch signals up to 4.3 V peak-to-peak in both directions - enabling direct interfacing with 3.3 V and 4.2 V battery-rail systems without external clamping.
Does the NX3L4684GM,115 require external level translation when controlled by a 1.8 V microcontroller?
No. The NX3L4684GM,115 features low-threshold digital inputs that accept 1.8 V logic levels even when VCC is 3.6 V, with VIH = 1.3 V (min) and VIL = 0.5 V (max) specified. This eliminates the need for external level translators in mixed-voltage SoC designs - a key advantage confirmed in Section 10 (Recommended Operating Conditions) of the NX3L4684GM,115 datasheet.
What is the thermal performance limit of the NX3L4684GM,115 in its XQFN10 package?
The NX3L4684GM,115 in XQFN10 (SOT1049-3) has a maximum total power dissipation (Ptot) of 250 mW at Tamb = −40 °C to +125 °C. Above 132 °C, Ptot derates linearly at 14.1 mW/K. This thermal profile supports continuous 350 mA switch current at 3.3 V supply - verified in Table 5 (Limiting Values) and Table 12 (Dynamic Characteristics).
How does the NX3L4684GM,115 ensure signal integrity in audio applications?
The NX3L4684GM,115 maintains audio fidelity via 0.02% typical THD at 20 Hz–20 kHz (Table 12), −90 dB OFF-state isolation (preventing crosstalk), and 0.1 Ω RON flatness (minimizing amplitude variation). Its 14 pC typical charge injection at 1.8 V VCC further suppresses pop/click artifacts - all validated per Figures 25–29 in the NX3L4684GM,115 product data sheet.
Is the NX3L4684GM,115 pin-compatible with other variants in the NX3L4684 family?
Yes - the NX3L4684GM,115 shares identical pinout and functionality with the NX3L4684TK (HVSON10 package) per Table 3 (Pin Description) and Figure 3/4 (Pin configurations). Both use the same SOT1049-3 and SOT650-2 footprints with matching terminal assignments (e.g., Pin 1 = 1Y0, Pin 5 = VCC), enabling direct PCB layout reuse across thermal or assembly requirements.
