NXP Semiconductors NX3L2267GM,115

Overview

NX3L2267GM,115 from NXP Semiconductors is a dual low-ohmic SPDT analog switch configured as two independent 2:1 multiplexer/demultiplexer channels, each with Schmitt-trigger digital select inputs (1S/2S), common I/O (1Z/2Z), and dual I/Os (1Y0/1Y1 and 2Y0/2Y1). It operates from 1.4 V to 4.3 V supply, delivers 0.50 Ω typical ON resistance at 4.3 V, supports 1.8 V logic control in 3.3 V systems, and handles ±350 mA continuous switch current - enabling high-fidelity audio routing in portable media players.

For engineers reviewing the NX3L2267GM,115 datasheet, NX3L2267GM,115 pinout, NX3L2267GM,115 application, or NX3L2267GM,115 equivalent, key selection criteria include its break-before-make switching behavior, −90 dB OFF-state isolation at 100 kHz, 60 MHz −3 dB bandwidth, charge injection under 37 pC at 4.3 V, and guaranteed operation from −40 °C to +125 °C in XQFN10 (SOT1049-3) package.

Technical Context

The NX3L2267GM,115 implements CMOS transmission-gate architecture with integrated Schmitt-trigger inputs for noise immunity and rail-to-rail analog signal handling up to VCC. Its dual-channel design features independent control (1S/2S), bidirectional signal paths, and break-before-make timing (as low as 2 ns at 4.3 V) to prevent signal shorting during channel switching.

It supports 1.8 V logic-level compatibility across full 1.4–4.3 V VCC range, accepts input voltages exceeding VCC (up to 4.6 V), and maintains low supply current (≤5 µA additional ICC at 1.8 V VI, 4.3 V VCC) - enabling direct interfacing with low-voltage microcontrollers without level shifters in battery-powered applications.

FAQ

What is the maximum analog signal voltage the NX3L2267GM,115 can switch?

The NX3L2267GM,115 supports analog signal voltages from −0.5 V to VCC + 0.5 V per IEC60134 limiting values. At VCC = 4.3 V, this allows signals up to +4.8 V peak, enabling rail-to-rail operation in most 3.3 V and 4.3 V systems. Exceeding these limits risks permanent damage unless clamping current ratings (±50 mA) are strictly observed.

Does the NX3L2267GM,115 require external pull-up or pull-down resistors on its select inputs?

No, the NX3L2267GM,115 does not require external pull-up or pull-down resistors on 1S or 2S inputs. Its Schmitt-trigger inputs provide built-in hysteresis and defined logic thresholds across the full 1.4–4.3 V supply range, ensuring reliable switching even with slow-rising control signals or noisy PCB environments.

Can the NX3L2267GM,115 be used in audio applications with 24-bit/192 kHz I²S signals?

Yes, the NX3L2267GM,115 supports 24-bit/192 kHz I²S signals due to its 60 MHz −3 dB bandwidth and low 0.02% THD at 2.7 V. Its 35 pF OFF-state capacitance and −90 dB isolation minimize crosstalk between adjacent data lines, preserving jitter performance and dynamic range in high-resolution audio paths.

Is the NX3L2267GM,115 pin-compatible with the NX3L2267GU variant?

No, the NX3L2267GM,115 (SOT1049-3) and NX3L2267GU (SOT1160-1) share the same XQFN10 footprint but differ in pin mapping: GM uses pin 1 = 1Y0, pin 9 = 1Z; GU uses pin 1 = 2Y1, pin 9 = VCC. PCB layout must be redesigned when substituting between these variants - they are not drop-in replacements.

What thermal considerations apply to the NX3L2267GM,115 in continuous 350 mA operation?

At 350 mA continuous switch current and 4.3 V VCC, power dissipation reaches ~180 mW (RON × I²). The SOT1049-3 package derates linearly above 132 °C at 14.1 mW/K. With proper PCB copper pour (≥1 cm² thermal pad), junction temperature remains within safe limits up to +105 °C ambient - verified per JEDEC JESD51-7 standards.
