onsemi NLU2G06AMX1TCG

Overview

NLU2G06AMX1TCG from onsemi is a dual CMOS inverter with open-drain outputs, designed for level-shifting and wired-OR logic applications in space-constrained systems. It operates from 1.65 V to 5.5 V, delivers 3.8 ns typical propagation delay at 5.0 V, supports ±12.5 mA output sink current, and features overvoltage-tolerant (OVT) inputs/outputs up to 7.0 V - enabling robust interfacing between mixed-voltage domains in portable IoT sensors.

For engineers reviewing the NLU2G06AMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain drive capability, ultra-small UDFN6 (1.45 × 1.0 mm) footprint, overvoltage tolerance, input power-down protection, and guaranteed operation across −55 °C to +125 °C industrial temperature range.

Technical Context

The NLU2G06AMX1TCG implements two independent inverting buffers with open-drain outputs, requiring external pull-up resistors for logic high assertion. Its input structure includes power-down protection that prevents back-current flow when V_CC = 0 V, and OVT pins allow safe operation with input/output signals exceeding supply voltage - critical for I²C bus arbitration and mixed-supply voltage translation.

AC performance is characterized with 15 pF and 50 pF loads, supporting data rates up to ~100 MHz (based on t_PZL = 3.8 ns typ @ 5 V, CL = 15 pF). The device uses standard CMOS process technology with ESD protection per JESD22-A114 (>2 kV HBM), and latch-up immunity of ±500 mA per JESD78.

FAQ

What is the maximum input voltage the NLU2G06AMX1TCG can tolerate when V_CC = 1.8 V?

The NLU2G06AMX1TCG supports input voltages from −0.5 V to +7.0 V regardless of V_CC level, confirmed in the Maximum Ratings table. This overvoltage tolerance (OVT) allows safe connection to 5 V or 3.3 V buses while powered from 1.8 V - a key feature distinguishing the NLU2G06AMX1TCG from standard logic gates. No external clamping is required.

Does the NLU2G06AMX1TCG support I²C bus operation with 1.8 V MCU and 3.3 V peripherals?

Yes - the NLU2G06AMX1TCG is explicitly suited for I²C level translation. Its open-drain outputs, OVT inputs/outputs, and 1.65–5.5 V V_CC range allow direct connection between 1.8 V controllers and 3.3 V peripherals. External pull-up resistors to 3.3 V complete the interface, and the NLU2G06AMX1TCG's 12.5 mA sink capability ensures compliant bus timing per I²C Fast-mode specifications.

What is the thermal pad connection requirement for the UDFN6 package of the NLU2G06AMX1TCG?

The UDFN6 package of the NLU2G06AMX1TCG includes an exposed thermal pad (Case 517AQ) that must be soldered to a PCB thermal land for optimal thermal performance and mechanical reliability. Per onsemi's mounting guidelines, the pad should be connected to GND or a dedicated thermal plane using ≥4 thermal vias (0.3 mm diameter) to inner layers. Leaving the pad unconnected degrades power dissipation and may compromise long-term solder joint integrity.

Can the NLU2G06AMX1TCG outputs be paralleled for higher current drive?

No - paralleling the two open-drain outputs of the NLU2G06AMX1TCG is not recommended. Each output has independent internal structure and slight propagation delay mismatch (≤0.5 ns), which may cause shoot-through or timing glitches during transitions. For higher sink current, use a single output with appropriately sized external pull-up or select a dedicated driver IC. The NLU2G06AMX1TCG is optimized for dual independent channel operation, not current stacking.

Is the NLU2G06AMX1TCG pin-compatible with other variants in the NLU2G06 family?

No - the NLU2G06AMX1TCG uses Case 517AQ (UDFN6, 1.45 × 1.0 mm, 0.5 mm pitch), while NLU2G06MUTCG uses Case 517AA (1.2 × 1.0 mm, 0.4 mm pitch) and NLU2G06CMUTCG uses Case 517BX (1.0 × 1.0 mm, 0.35 mm pitch). Though functionally identical, these variants have different footprints and pin pitches; PCB layout must be specific to the exact variant. The NLU2G06AMX1TCG is not a drop-in replacement for other NLU2G06 suffixes.
