NXP Semiconductors NX3L2267GU-Q100X

Overview

NX3L2267GU-Q100 from NXP Semiconductors is a dual low-ohmic SPDT analog switch qualified to AEC-Q100 Grade 1 for automotive use. It functions as a 2:1 multiplexer/demultiplexer with break-before-make switching, 0.50 Ω typical ON resistance at 4.3 V supply, and supports 1.8 V logic control in 3.3 V systems-enabling direct interfacing with low-voltage controllers in infotainment signal routing.

For engineers reviewing the NX3L2267GU-Q100 datasheet, NX3L2267GU-Q100 pinout, NX3L2267GU-Q100 application, or NX3L2267GU-Q100 equivalent, key selection criteria include its 1.4 V to 4.3 V wide supply range, −40 °C to +125 °C automotive temperature rating, 350 mA continuous switch current, sub-50 ns enable/disable timing, and IEC61000-4-2 8 kV ESD protection on switch ports.

Technical Context

The NX3L2267GU-Q100 integrates two independent SPDT switches, each with Schmitt-trigger digital select inputs (1S/2S) enabling robust operation with slow-rising control signals. Its CMOS architecture delivers rail-to-rail analog signal handling up to VCC with minimal distortion-verified by <0.02% THD at 2.3 V–4.3 V supplies and 20 Hz–20 kHz audio bandwidth.

Break-before-make timing is guaranteed by design (≤10 ns at 3.6–4.3 V), preventing momentary shorting during channel transitions. Input voltage tolerance exceeds VCC (up to 4.6 V), and leakage currents remain below ±100 nA across temperature, supporting high-impedance sensor or audio line switching without signal corruption.

FAQ

What is the maximum signal voltage the NX3L2267GU-Q100 can switch?

The NX3L2267GU-Q100 supports analog signals from GND to VCC, with absolute maximum switch voltage rated at VCC + 0.5 V (up to 4.6 V). This allows full rail-to-rail signal transmission-for example, switching a 4.3 V audio signal with a 4.3 V supply-without distortion or clipping, as confirmed in the recommended operating conditions table.

Does the NX3L2267GU-Q100 require external level shifters when driven by 1.8 V logic?

No, the NX3L2267GU-Q100 does not require external level shifters. Its low-threshold Schmitt-trigger inputs accept 1.8 V logic levels even at 3.6 V VCC, with VIH specified at 1.3 V (min) and VIL at 0.5 V (max) in that condition-enabling direct connection to low-voltage microcontrollers while maintaining low ICC and noise immunity.

What is the thermal derating behavior of the NX3L2267GU-Q100 in its SOT1160-1 package?

For the SOT1160-1 (XQFN10) package, total power dissipation derates linearly above +128 °C at 11.5 mW/K. The device is rated for continuous operation from −40 °C to +125 °C, with Ptot = 250 mW at ambient temperatures within that range. Derating begins only beyond the specified maximum junction temperature limit.

How does the NX3L2267GU-Q100 ensure signal integrity in audio applications?

The NX3L2267GU-Q100 ensures audio signal integrity through 0.02% typical THD at 2.3–4.3 V supplies, −90 dB OFF-state isolation at 100 kHz, and 60 MHz −3 dB bandwidth. These parameters-measured per Figure 18–20 in the datasheet-enable clean, low-noise stereo routing in automotive head units and portable media players without added filtering.

Is the NX3L2267GU-Q100 pin-compatible with other variants in the NX3L2267-Q100 family?

Yes, the NX3L2267GU-Q100 shares identical pin configuration (SOT1160-1) and function with the NX3L2267GM-Q100 (SOT1049-3), though the packages differ in footprint (1.40 × 1.80 mm vs. 1.55 × 2.00 mm). Both use the same pin numbering per Table 3 and support identical electrical operation-allowing layout reuse where package height and board space permit.
