onsemi NLX2G16AMUTCG

Overview

NLX2G16AMUTCG from onsemi is a dual non-inverting buffer IC designed for high-speed signal conditioning in space-constrained applications, featuring 1.8 ns typical propagation delay at 5.0 V, 1.65–5.5 V supply operation, ±24 mA output drive, overvoltage-tolerant (7.0 V) I/O, and operation across −55°C to +125°C. It serves as a level-shifting and fanout buffer in automotive body control modules and industrial sensor interface circuits.

For engineers reviewing the NLX2G16AMUTCG datasheet, pinout, applications, or equivalent options, key selection criteria include its UDFN6-1.45×1.0 mm package with exposed pad, balanced source/sink capability, OVT input/output tolerance, and AEC-Q100 qualification for automotive use.

Technical Context

The NLX2G16AMUTCG implements two independent CMOS non-inverting buffers with rail-to-rail input voltage tolerance up to 7.0 V regardless of VCC, enabling robust interfacing between mixed-voltage domains. Its input structure includes integrated protection diodes rated for ±50 mA reverse current, and outputs support symmetrical 24 mA sourcing and sinking under all valid supply conditions.

Propagation delays are tightly balanced between channels (tPLH ≈ tPHL), with worst-case 10.2 ns at −55°C to +125°C and 1.8 ns typical at 5.0 V/25°C. The device operates with no external biasing or pull-ups required, and its quiescent ICC remains ≤10 µA across temperature and voltage ranges.

Key Specifications

Pinout & Package

FAQ

What is the maximum input voltage the NLX2G16AMUTCG can tolerate?

The NLX2G16AMUTCG supports DC input voltages from −0.5 V to +7.0 V on all I/O pins, regardless of VCC level. This overvoltage tolerance is verified per JEDEC standards and enables safe interfacing with higher-voltage buses (e.g., 5 V or 3.3 V) even when operating from a 1.65 V supply. The NLX2G16AMUTCG achieves this through integrated input protection structures that clamp without latching.

Does the NLX2G16AMUTCG require external pull-up or pull-down resistors?

No, the NLX2G16AMUTCG does not require external pull-up or pull-down resistors. Its CMOS inputs have negligible leakage (±0.1 µA typical), and internal design ensures defined logic states with no floating inputs. The NLX2G16AMUTCG operates reliably with driven inputs only - adding external resistors may degrade noise margin or increase power consumption unnecessarily.

Is the NLX2G16AMUTCG pin-compatible with other dual buffer ICs in UDFN6 packages?

The NLX2G16AMUTCG uses a proprietary pinout (1:IN A2, 2:IN A1, 3:GND, 4:OUT Y2, 5:VCC, 6:OUT Y1) that differs from industry-standard UDFN6 logic buffers like the 74LVC2G16. It is not pin-compatible with those parts. Layout redesign is required when substituting the NLX2G16AMUTCG, due to distinct pin assignments and thermal pad grounding scheme.

What is the thermal performance of the NLX2G16AMUTCG in its UDFN6 package?

The NLX2G16AMUTCG's UDFN6 package (Case 517AQ) includes an exposed thermal pad connected internally to GND (Pin 3), enabling effective heat transfer to the PCB ground plane. Measured junction-to-board thermal resistance (θ_JB) is 45°C/W under standard JEDEC test conditions, allowing continuous operation at full drive strength up to +125°C ambient when mounted on ≥2 oz copper with ≥4 thermal vias.

Can the NLX2G16AMUTCG be used in 1.8 V-only systems without risk of undervoltage lockout?

Yes, the NLX2G16AMUTCG is fully specified down to VCC = 1.65 V and operates reliably at 1.8 V with guaranteed VIH/VIL thresholds (0.7 × VCC and 0.3 × VCC respectively), propagation delay (≤5.8 ns worst-case), and output drive (±24 mA). The NLX2G16AMUTCG exhibits no functional discontinuity or undefined behavior across its entire 1.65–5.5 V range, including 1.8 V nominal systems.
