onsemi NLX2GU04AMX1TCG

Overview

NLX2GU04AMX1TCG from onsemi is a dual unbuffered CMOS inverter optimized for crystal oscillator circuits, pulse shaping, and high-impedance analog amplification. It operates from 1.65 V to 5.5 V, delivers ±16 mA balanced output drive, features overvoltage-tolerant (OVT) I/O pins up to 7.0 V, and uses an ultra-small ULLGA6 (1.45 × 1.0 mm) package.

For engineers reviewing the NLX2GU04AMX1TCG datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated pin-level behavior, confirmed OVT capability, real-world oscillator use context, and two technically documented alternative parts with explicit differences.

Technical Context

The NLX2GU04AMX1TCG implements two independent unbuffered inverter stages-no internal buffering enables direct crystal connection and preserves phase integrity in Pierce oscillator topologies. Its input and output structures are designed with overvoltage tolerance, allowing safe operation even when signals exceed VCC by up to 2.5 V.

Propagation delays are balanced between rising and falling edges (tPLH ≈ tPHL), with typical values of 0.5 ns at 5.0 V (CL = 15 pF, RL = 1 MΩ). Input capacitance is 7 pF and output capacitance is 8 pF at 5.5 V, supporting low-jitter timing performance in sensitive analog-digital interface applications.

FAQ

What is the primary circuit role of the NLX2GU04AMX1TCG?

The NLX2GU04AMX1TCG serves as a dual unbuffered CMOS inverter, primarily used in Pierce crystal oscillator configurations, pulse shaping networks, and high-impedance analog amplifier biasing. Its unbuffered architecture avoids internal phase shift, making it essential for stable oscillator loop gain and precise waveform edge control in the NLX2GU04AMX1TCG.

Does the NLX2GU04AMX1TCG support operation below 1.65 V?

No-the NLX2GU04AMX1TCG is not characterized or guaranteed for operation below 1.65 V. The recommended minimum VCC is 1.65 V per the datasheet's Recommended Operating Conditions table; operation at lower voltages may result in undefined logic states, increased propagation delay, or failure to oscillate in crystal applications using the NLX2GU04AMX1TCG.

Can the NLX2GU04AMX1TCG be used with a 7 V input signal while powered from 3.3 V?

Yes-the NLX2GU04AMX1TCG features overvoltage-tolerant (OVT) inputs and outputs rated to 7.0 V regardless of VCC level. This allows safe interfacing with 5 V or 7 V signals in mixed-voltage systems while operating the NLX2GU04AMX1TCG from 3.3 V, without external clamping diodes or level shifters.

What package type does the NLX2GU04AMX1TCG use, and is it RoHS compliant?

The NLX2GU04AMX1TCG uses the ULLGA6 package (1.45 × 1.0 mm, 0.5 mm pitch), a leadless land-grid array with exposed thermal pad. It is Pb-free and RoHS compliant, meeting JEDEC standards for moisture sensitivity level 1 and reflow compatibility per J-STD-020.

How does the NLX2GU04AMX1TCG differ from the buffered NLX2G04 variant?

The NLX2GU04AMX1TCG is unbuffered-critical for crystal oscillator use-while the NLX2G04 is buffered and intended for general-purpose digital inversion. Buffering adds propagation delay and internal capacitance, degrading oscillator phase margin and start-up reliability. The NLX2GU04AMX1TCG's unbuffered design ensures minimal loading and predictable loop gain in timing circuits.
