onsemi NLU1G04CMX1TCG

Overview

NLU1G04CMX1TCG from onsemi is a single high-speed CMOS inverter in a 1.0 mm × 1.0 mm UDFN6 package, operating from 1.65 V to 5.5 V supply, with 3.5 ns typical propagation delay at 5.0 V and overvoltage-tolerant (OVT) I/O pins rated to ±7.0 V - used for signal inversion in space-constrained industrial control and portable sensor interface circuits.

For engineers reviewing the NLU1G04CMX1TCG datasheet, pinout, applications, or equivalent options, key selection considerations include its ultra-small footprint, input/output overvoltage tolerance up to 7.0 V independent of VCC, guaranteed operation across −55°C to +125°C, and low quiescent current of 1.0 µA max at 25°C.

Technical Context

The NLU1G04CMX1TCG implements a single unbuffered inverter logic function with balanced tPLH/tPHL propagation delays and power-down protection on all inputs. Its OVT architecture allows safe interfacing with higher-voltage signals without external level-shifting circuitry.

It supports rail-to-rail digital input (0–5.5 V) and output swing under load, maintains specified VOH/VOL across full temperature range, and features ESD robustness >2 kV HBM - enabling direct use in mixed-voltage domains and noisy industrial environments.

FAQ

What is the maximum input voltage the NLU1G04CMX1TCG can tolerate when VCC is unpowered?

The NLU1G04CMX1TCG supports input voltages from −0.5 V to +7.0 V regardless of VCC state, including VCC = 0 V. This overvoltage tolerance is enabled by dedicated protection structures on IN A and OUT Y pins, allowing safe connection to live 5 V buses during power-down sequences without latch-up or damage - a key advantage over standard LVC inverters like the SN74LVC1G04DBVR. The NLU1G04CMX1TCG remains fully functional after such events.

Does the NLU1G04CMX1TCG require external pull-up or pull-down resistors on unused pins?

Pins 2 and 4 of the NLU1G04CMX1TCG are NC (no connect) and must remain unconnected - no pull-up, pull-down, or grounding is required or recommended. The device contains internal power-down protection that maintains high-impedance behavior on IN A when VCC is absent, eliminating need for external biasing. Adding external resistors to NC pins may compromise thermal performance or cause unintended coupling in high-density layouts.

Can the NLU1G04CMX1TCG drive a 50 pF capacitive load at 10 MHz while maintaining timing specs?

Yes - the NLU1G04CMX1TCG specifies tPLH/tPHL ≤ 10.0 ns at VCC = 4.5–5.5 V with CL = 50 pF and TA = 25°C. At 10 MHz (100 ns period), this leaves >90 ns margin for setup/hold and propagation, ensuring reliable operation. Its CPD = 8.0 pF and low output impedance support clean edges into 50 pF loads without overshoot, verified in onsemi's Figure 4 test circuit. The NLU1G04CMX1TCG meets this requirement across −55°C to +125°C when derated per AC Electrical Characteristics table.

Is the thermal pad on the bottom of the NLU1G04CMX1TCG package electrically connected?

No - the exposed thermal pad on the NLU1G04CMX1TCG (UDFN6, 1.0 × 1.0 mm) is not electrically connected to any internal node; it serves solely for thermal conduction to the PCB. Per onsemi's mechanical drawing 98AON30313E, the pad is isolated and should be soldered to a dedicated thermal copper pour tied to GND for optimal heat dissipation. Connecting it to VCC or leaving it floating degrades thermal performance but does not affect logic functionality.

How does the NLU1G04CMX1TCG behave during power sequencing when VCC ramps slower than input signals?

The NLU1G04CMX1TCG features power-down protection that keeps inputs high-impedance and prevents back-current flow even when VIN is applied before VCC stabilizes. Its OVT structure blocks conduction paths until VCC reaches ~0.8 V, avoiding false outputs or supply rail injection. This behavior is validated per JEDEC JESD78 latch-up testing and enables robust operation in systems with asynchronous power domains - a capability not guaranteed in non-OVT inverters such as the 74LVC1G04GW,125. The NLU1G04CMX1TCG maintains defined logic states throughout ramp-up.
