NXP Semiconductors NX3L2267GU,115

Overview

NX3L2267GU,115 from NXP Semiconductors is a dual low-ohmic SPDT analog switch optimized for 2:1 multiplexing/demultiplexing of analog or digital signals. It features 0.50 Ω typical ON resistance at 4.3 V supply, break-before-make switching, and operates across 1.4 V to 4.3 V supply with −40 °C to +125 °C temperature range. It enables 4.3 V signal routing under 1.8 V logic control in portable audio interfaces.

For engineers reviewing the NX3L2267GU,115 datasheet, NX3L2267GU,115 pinout, NX3L2267GU,115 application, or NX3L2267GU,115 equivalent, key selection criteria include ON resistance flatness (0.23 Ω max), charge injection (37 pC at 4.3 V), isolation (−90 dB), THD (0.02 %), and XQFN10 (SOT1160-1) package compatibility with high-density portable PCB layouts.

Technical Context

The NX3L2267GU,115 integrates two independent SPDT switches, each with Schmitt-trigger select inputs enabling robust operation with slow-rising control signals. Its CMOS architecture supports bidirectional signal flow between common port (nZ) and either nY0 or nY1, with voltage translation capability: 1.8 V logic reliably controls 4.3 V analog paths without external level shifters.

Break-before-make timing is guaranteed by design (tb-m ≤ 10 ns at VCC ≥ 2.7 V), preventing momentary shorting during channel switching. Input clamping and ESD protection (6 kV IEC61000-4-2 contact, 7.5 kV HBM) ensure reliability in handheld device environments subject to electrostatic discharge.

FAQ

What is the maximum signal voltage the NX3L2267GU,115 can switch?

The NX3L2267GU,115 supports bidirectional analog signal switching up to VCC, with absolute maximum switch voltage rated at VCC + 0.5 V (up to +4.6 V). At its maximum rated supply of 4.3 V, the device reliably routes signals up to 4.3 V peak-to-peak without distortion or latch-up, provided switch current remains within ±350 mA continuous limits. This makes NX3L2267GU,115 suitable for Li-ion battery-powered systems operating near full charge voltage.

Does the NX3L2267GU,115 require external pull-up or pull-down resistors on its select inputs?

No, the NX3L2267GU,115 incorporates Schmitt-trigger action on both 1S and 2S inputs, providing built-in hysteresis (typically 0.3 V) that eliminates the need for external pull-up or pull-down resistors. This feature ensures reliable switching even with slow-rising or noisy control signals, and allows direct connection to open-drain or floating GPIO outputs. The NX3L2267GU,115's VIH/VIL thresholds are defined across the full 1.4–4.3 V supply range, confirming robust logic-level acceptance without external biasing.

Can the NX3L2267GU,115 be used in bidirectional signal paths such as I²C or UART lines?

Yes, the NX3L2267GU,115 supports fully bidirectional signal flow on all ports (nZ ↔ nY0/nY1), making it suitable for passive multiplexing of I²C, UART, and other bidirectional digital buses. Its low ON capacitance (135 pF) and fast enable time (22 ns typical) preserve signal edge integrity, while the break-before-make architecture prevents bus contention during switching. However, for I²C, verify pull-up resistor placement relative to switch location to maintain rise-time compliance per bus speed grade - the NX3L2267GU,115 itself introduces no directionality or protocol awareness.

What thermal derating applies to the NX3L2267GU,115 in its SOT1160-1 package?

For the NX3L2267GU,115 in SOT1160-1 (XQFN10) package, total power dissipation (Ptot) derates linearly above +128 °C at 11.5 mW/K. At ambient temperatures ≤128 °C, the device supports up to 250 mW continuous dissipation. Above this threshold, allowable power decreases proportionally - e.g., at +138 °C, Ptot must be limited to 238.5 mW. This derating ensures safe operation under sustained high-temperature conditions typical in sealed portable enclosures, and applies regardless of whether power is dissipated in the switch path or supply rail.

How does the NX3L2267GU,115 achieve 1.8 V logic compatibility while operating at 3.6 V supply?

The NX3L2267GU,115 achieves 1.8 V logic compatibility through internally scaled input threshold voltages: at VCC = 3.6 V, VIH is specified at 1.3 V (max), and VIL at 0.5 V (max), allowing reliable recognition of 1.8 V logic HIGH/LOW states without exceeding supply current limits. This is implemented via dedicated input stage biasing - not level translation - so the NX3L2267GU,115 draws only 1 μA additional supply current when driven by 1.8 V logic at 3.6 V VCC, enabling direct MCU interface without external components.
