onsemi NLU1G04BMX1TCG

Overview

NLU1G04BMX1TCG from onsemi is a single high-speed CMOS inverter in an ultra-small UDFN6 (1.45 mm × 1.0 mm) package, designed for logic-level signal inversion in space-constrained applications. It operates from 1.65 V to 5.5 V, delivers 3.5 ns typical propagation delay at 5.0 V, supports ±12.5 mA output drive, and features overvoltage-tolerant (OVT) inputs/outputs up to 7.0 V - enabling robust interfacing in mixed-voltage systems such as portable sensor nodes and IoT edge controllers.

For engineers reviewing the NLU1G04BMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its OVT input tolerance, ultra-small 1.45×1.0 mm UDFN6 footprint, guaranteed operation down to −55°C, low ICC (≤10 µA max), and balanced tPLH/tPHL timing essential for clean digital signal conditioning in battery-powered microcontroller peripherals.

Technical Context

The NLU1G04BMX1TCG implements a single CMOS inverter stage with rail-to-rail input voltage range (−0.5 V to +7.0 V) independent of VCC, enabling safe hot-swap and level-shifting capability. Its input structure includes power-down protection and ESD robustness (>2 kV HBM), while output drive is symmetric (±12.5 mA) with guaranteed VOL ≤ 0.44 V at IOL = 8 mA and VOH ≥ 2.48 V at IOH = −8 mA under 3.0–5.5 V supply.

AC performance is characterized with CL = 15 pF and input transition rates up to 100 ns/V (at 3.3 V) or 20 ns/V (at 5.0 V). Propagation delay varies from 3.5 ns (typ, 5.0 V, CL = 15 pF) to 10.0 ns (max, 3.0–3.6 V, CL = 50 pF), and input capacitance is specified at 4–10 pF - confirming suitability for high-frequency clock buffering and data path inversion in sub-100 MHz digital subsystems.

FAQ

What is the maximum input voltage the NLU1G04BMX1TCG can safely tolerate?

The NLU1G04BMX1TCG supports DC input voltages from −0.5 V to +7.0 V regardless of VCC level, verified per its Absolute Maximum Ratings table. This overvoltage tolerance applies to both IN A and OUT Y pins, enabling safe operation during power sequencing, hot-swap events, and mixed-voltage domain interfacing without external clamping components. The NLU1G04BMX1TCG maintains functional integrity and avoids latch-up under these conditions per JESD78 testing.

Does the NLU1G04BMX1TCG require external pull-up or pull-down resistors on its inputs?

No, the NLU1G04BMX1TCG does not require external biasing resistors on IN A because its CMOS input structure has inherently high impedance (IIN ≤ ±1.0 µA) and defined VIH/VIL thresholds that scale with VCC (e.g., VIH = 0.7×VCC min). However, floating inputs must be avoided in practice - either tie unused inputs to VCC or GND, or use the NC pins appropriately. The NLU1G04BMX1TCG's power-down protection ensures safe behavior even when VCC = 0 V.

Can the NLU1G04BMX1TCG drive a 50 pF capacitive load at 10 MHz?

Yes, the NLU1G04BMX1TCG is characterized for CL = 50 pF with tPLH/tPHL ≤ 10.0 ns (max) at VCC = 3.0–3.6 V, confirming reliable switching into 50 pF loads. At 10 MHz (100 ns period), the propagation delay represents <10% of the cycle time, leaving ample margin for setup/hold timing. Output drive strength (±12.5 mA) ensures fast edge rates, and CPD = 8.0 pF (at 5.0 V) indicates low dynamic power consumption - making the NLU1G04BMX1TCG suitable for this use case.

Is the NLU1G04BMX1TCG pin-compatible with other UDFN6 inverters like the SN74LVC1G04 in the same package?

No, the NLU1G04BMX1TCG is not pin-compatible with SN74LVC1G04 variants in UDFN6. While both use 6-pin UDFN packages, the NLU1G04BMX1TCG pinout is GND–NC–IN A–NC–OUT Y–VCC (pin 1–6), whereas SN74LVC1G04DBV uses GND–IN–VCC–NC–OUT–NC. Physical layout, terminal assignment, and NC pin locations differ - PCB redesign is required for substitution. Always verify pin mapping using the official NLU1G04BMX1TCG datasheet before layout reuse.

What is the thermal performance of the NLU1G04BMX1TCG in its UDFN6 package?

The NLU1G04BMX1TCG in UDFN6 (case 517AQ) features an exposed thermal pad that enhances heat dissipation. Its maximum junction temperature is 150°C, and thermal resistance (θJA) is not explicitly published, but typical UDFN6 devices with similar die size and pad exposure achieve θJA ≈ 180–220°C/W on 2-layer FR4 with minimal copper. For continuous operation at 125°C ambient, power dissipation must remain below ~15 mW - well within the NLU1G04BMX1TCG's ICC × VCC limit (≤55 µW at 5.5 V, 10 µA).
