onsemi NLX2G06AMX1TCG

Overview

NLX2G06AMX1TCG from onsemi is a dual CMOS inverter with open-drain outputs, designed for level-shifting and wired-OR logic in space-constrained applications. It operates from 1.65 V to 5.5 V, delivers 2.4 ns typical propagation delay at 5.0 V, supports ±50 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 and industrial control I/O modules.

For engineers reviewing the NLX2G06AMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its UDFN6 1.45 × 1.0 mm package, open-drain topology for bus arbitration, OVT capability eliminating external clamping diodes, and guaranteed operation across −55°C to +125°C ambient.

Technical Context

The NLX2G06AMX1TCG implements two independent inverting buffers with open-drain outputs, requiring external pull-up resistors for logic high assertion. Its input structure tolerates voltages up to 7.0 V regardless of VCC, enabling direct connection to higher-voltage buses without level translators.

Each inverter exhibits balanced tPZL/tPLZ propagation delays (e.g., 2.4 ns typ at 5.0 V), low ICC ≤ 1 µA max at 25°C, and power-down input protection that prevents back-driving during VCC-off conditions - critical for hot-swap and partial-power-down systems.

FAQ

What is the maximum allowable input voltage for NLX2G06AMX1TCG when VCC = 0 V?

The NLX2G06AMX1TCG supports overvoltage-tolerant inputs up to +7.0 V and down to −0.5 V regardless of VCC state. When VCC = 0 V, the input pins remain protected and will not back-drive the supply rail due to integrated power-down protection - a key feature enabling safe hot-plug operation in modular systems using NLX2G06AMX1TCG.

Can NLX2G06AMX1TCG be used as a level shifter between 1.8 V and 5 V logic domains?

Yes - the NLX2G06AMX1TCG can translate signals from a 1.8 V MCU output to a 5 V bus by connecting VCC to 1.8 V and using a 5 V pull-up on the open-drain output. Its OVT inputs accept 5 V signals even at 1.8 V VCC, and the output sinks current compatible with 5 V TTL thresholds - making NLX2G06AMX1TCG ideal for bidirectional level shifting in compact designs.

Does NLX2G06AMX1TCG require external pull-up resistors on its outputs?

Yes - because NLX2G06AMX1TCG features open-drain outputs, external pull-up resistors are mandatory to establish a logic HIGH state. The value depends on bus capacitance and speed requirements; typical values range from 1 kΩ (for fast rise times) to 10 kΩ (for low power). NLX2G06AMX1TCG itself does not provide internal pull-ups.

What is the thermal performance of NLX2G06AMX1TCG in its UDFN6 package?

The NLX2G06AMX1TCG UDFN6 package includes an exposed thermal pad that enhances heat dissipation. With proper PCB copper pour (≥ 100 mm² thermal pad connection), junction-to-ambient thermal resistance (θJA) is approximately 180°C/W - sufficient for continuous operation at full 50 mA sink per output within its −55°C to +125°C rating. This thermal behavior is validated in NLX2G06AMX1TCG's official thermal characterization data.

Is NLX2G06AMX1TCG pin-compatible with other variants in the NLX2G06 family?

No - NLX2G06AMX1TCG uses the UDFN6 1.45 × 1.0 mm package (Case 517AQ), while NLX2G06MUTCG uses 1.2 × 1.0 mm (517AA) and NLX2G06CMUTCG uses 1.0 × 1.0 mm (517BX). Though all share identical pinout numbering and function, their land patterns differ; PCB layout must match the specific variant's dimensions. NLX2G06AMX1TCG is not mechanically interchangeable with other NLX2G06 suffixes without board revision.
