onsemi NLU1GU04CMX1TCG

Overview

NLU1GU04CMX1TCG from onsemi is a single unbuffered CMOS inverter in a 1.0 mm × 1.0 mm UDFN6 package, featuring 2.5 ns typical propagation delay at 5.0 V, overvoltage-tolerant I/O (±7.0 V), and ±12.5 mA output drive-designed for oscillator circuits, pulse shaping, and high-impedance amplifier interfaces.

For engineers reviewing the NLU1GU04CMX1TCG datasheet, pinout, applications, or equivalent options, key selection considerations include its ultra-small footprint, rail-to-rail input tolerance independent of V_CC, guaranteed operation from −55°C to +125°C, and Pb-free UDFN6 packaging with MSL Level 1 rating.

Technical Context

The NLU1GU04CMX1TCG implements a single-stage CMOS inverter topology without internal buffering, delivering balanced t_PLH/t_PHL delays and low-input-capacitance (4 pF typical) for high-speed signal inversion. Its overvoltage-tolerant input/output structure enables safe interfacing with mixed-voltage systems.

It operates across 1.65 V to 5.5 V supply range with guaranteed logic thresholds (V_IL ≤ 0.20×V_CC, V_IH ≥ 0.80×V_CC) and supports dynamic loads up to 50 pF while maintaining sub-10 ns propagation delay at 3.3 V and 5.0 V.

FAQ

What is the maximum supply voltage rating for the NLU1GU04CMX1TCG?

The NLU1GU04CMX1TCG supports a DC supply voltage (V_CC) range of −0.5 V to +7.0 V, with recommended operation from 1.65 V to 5.5 V. This overvoltage rating applies to both supply and I/O pins, allowing safe operation even when V_CC is unpowered or at intermediate levels. The absolute maximum rating ensures robustness during power sequencing and transient events without damage to the NLU1GU04CMX1TCG.

Does the NLU1GU04CMX1TCG require external pull-up or pull-down resistors on its inputs?

No, the NLU1GU04CMX1TCG does not require external pull-up or pull-down resistors on its IN A pin. Its CMOS input structure has negligible DC leakage (< ±1.0 µA) and defined switching thresholds (V_IL ≤ 0.20×V_CC, V_IH ≥ 0.80×V_CC). However, floating inputs must be avoided in system design; unused inputs should be tied to V_CC or GND. The NLU1GU04CMX1TCG's internal structure provides no built-in biasing, so external termination is only needed for signal integrity-not logic state definition.

Can the NLU1GU04CMX1TCG drive a 50 pF load at 10 MHz without signal degradation?

Yes, the NLU1GU04CMX1TCG can reliably drive a 50 pF load at 10 MHz. At V_CC = 5.0 V, its t_PLH/t_PHL is specified at 8.0 ns max under 50 pF load, supporting >100 MHz toggle rates. With ±12.5 mA output drive and low output impedance, it maintains clean edges and minimal overshoot. For sustained 10 MHz operation, ensure proper V_CC decoupling near the NLU1GU04CMX1TCG's pin 6 and minimize trace inductance to preserve signal fidelity.

What is the function of the NC pins on the NLU1GU04CMX1TCG UDFN6 package?

The NLU1GU04CMX1TCG has two NC (No Connect) pins - pin 2 and pin 4 - with no internal electrical connection. These pins may serve mechanical or thermal roles in the package mold but carry no circuit function. Per onsemi's recommendation, NC pins should be left floating or connected to GND for mechanical stability and EMI reduction; they must never be tied to V_CC or driven by external signals. Their presence does not affect the operation of the NLU1GU04CMX1TCG inverter core.

Is the NLU1GU04CMX1TCG suitable for automotive applications?

The NLU1GU04CMX1TCG is rated for operation from −55°C to +125°C and meets JEDEC JESD22 reliability standards, including ESD (HBM >2000 V) and latch-up (±500 mA). While it is not AEC-Q100 qualified out-of-box, its temperature range, robust overvoltage tolerance, and Pb-free construction make it suitable for non-safety-critical automotive subsystems such as body control modules, infotainment interfaces, and sensor signal conditioning - provided system-level validation confirms compliance with vehicle-specific requirements for the NLU1GU04CMX1TCG.
