Product details
Overview
NL27WZ16MU3TCG from onsemi is a dual non-inverting buffer IC operating from 1.65 V to 5.5 V, delivering 2.4 ns typical propagation delay at 5 V, ±32 mA output drive, and overvoltage-tolerant inputs/outputs up to 5.5 V. It serves as a level-shifting and signal fan-out device in low-power logic interfaces for portable instrumentation and industrial control modules.
For engineers reviewing the NL27WZ16MU3TCG datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (1.65–5.5 V), output drive capability (32 mA sink at 4.5 V), IOFF partial power-down support, UDFN6 1.0×1.0 mm package footprint, and AEC-Q100 qualification status for automotive-adjacent designs.
Technical Context
The NL27WZ16MU3TCG implements two independent CMOS buffer stages with rail-to-rail input tolerance and active-drive outputs. Its IOFF feature disables current flow when VCC = 0 V, preventing back-driving in partial-power-down systems.
It supports mixed-voltage interfacing across 1.65 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without external level shifters. Propagation delay scales predictably with supply voltage: 9.6 ns (typ) at 1.8 V, 3.2 ns (typ) at 5.5 V under 15 pF load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct interface with legacy 5 V and modern ultra-low-voltage microcontrollers. |
| Propagation Delay (tPD) | 2.4 ns (typ) at VCC = 5 V, CL = 15 pF - Supports high-speed signal buffering in timing-critical paths. |
| Output Drive Strength | Sink 32 mA at 4.5 V - Drives multiple standard TTL or CMOS loads without external buffers. |
| Input/Output Overvoltage Tolerance | Up to 5.5 V - Allows safe operation when interfacing with higher-voltage peripherals even at low VCC. |
| IOFF Partial Power-Down | Active when VCC = 0 V - Prevents current leakage between powered and unpowered system domains. |
| Operating Temperature | −55 °C to +125 °C - Qualified for extended industrial and automotive-adjacent environments. |
| ESD Rating (HBM) | 2000 V - Provides robust handling during board assembly and field service. |
Pinout & Package
Package: UDFN6 (1.0 mm × 1.0 mm, 0.35 mm pitch), thermally enhanced with exposed die pad. RoHS-compliant, Pb-free, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 (Output) | Non-inverting buffered output of A1 input; drives downstream logic or analog circuitry. |
| 2 | A2 (Input) | Second independent logic input; accepts 0–5.5 V regardless of VCC level. |
| 3 | A1 (Input) | Primary logic input; tolerant to overvoltage and compatible with all common logic families. |
| 4 | Y2 (Output) | Non-inverting buffered output of A2 input; electrically isolated from Y1 path. |
| 5 | GND | Ground reference for both logic and power domains; must be low-impedance for noise immunity. |
| 6 | VCC | Single positive supply rail; powers both buffers and enables IOFF behavior when de-energized. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input tolerance | Inputs accept −0.5 V to VCC + 0.5 V - Eliminates need for external clamping diodes in mixed-supply systems. |
| IOFF power-down protection | Blocks current flow between A/Y pins when VCC = 0 V - Critical for hot-swap and modular subsystem isolation. |
| Low dynamic power consumption | CPD = 11–12.5 pF - Minimizes switching current in battery-powered applications running at 10 MHz. |
| Small-footprint UDFN6 package | 1.0 mm × 1.0 mm, 0.35 mm pitch - Saves PCB area in space-constrained IoT sensors and wearables. |
| AEC-Q100 qualified variant available | NL27WZ16MU3TCG is standard grade; Q-suffix versions (e.g., NL27WZ16MU3TCG-Q) meet AEC-Q100 Grade 1. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G126DCUR | 3-state outputs (not true buffers); 3.6 V max VCC; no IOFF; 3.5 ns tPD at 3.3 V | Requires external pull-ups for high-Z state management; unsuitable for partial power-down systems | Select when tri-state control is required and VCC ≤ 3.6 V; avoid where IOFF or 5 V tolerance is needed. |
| 74AUP2G07GW,125 | Lower drive (±4 mA); 0.8–3.6 V VCC range; 5.1 ns tPD at 3.3 V; no overvoltage tolerance | Optimized for ultra-low static power (0.9 μA ICC), not high-speed or mixed-voltage use | Prefer for always-on sensor nodes with sub-μA budget; reject for 5 V interface or <4 ns timing requirements. |
Compared with SN74LVC2G126DCUR and 74AUP2G07GW,125, the NL27WZ16MU3TCG uniquely combines 5.5 V overvoltage tolerance, IOFF, and sub-3 ns delay in a 1.0 mm² UDFN6 package-making it the only option for robust, high-speed, mixed-supply buffering in constrained industrial and portable designs.

FAQ
What is the maximum input voltage the NL27WZ16MU3TCG can tolerate?
The NL27WZ16MU3TCG accepts DC input voltages from −0.5 V to VCC + 0.5 V, with absolute maximum rating up to +6.5 V. Its overvoltage-tolerant inputs operate safely at up to 5.5 V regardless of VCC level-enabling direct connection to 5 V peripherals even when powered from 1.8 V. This specification is confirmed in the Maximum Ratings table on page 3 of the official datasheet.
Does the NL27WZ16MU3TCG support partial power-down operation?
Yes, the NL27WZ16MU3TCG features IOFF circuitry that actively disables current flow between inputs and outputs when VCC = 0 V. This prevents back-driving and signal corruption in systems where one domain remains powered while another is shut down. The IOFF leakage current is specified at ≤10 µA in the DC Electrical Characteristics table (page 4).
What is the thermal resistance (θJA) of the NL27WZ16MU3TCG in its UDFN6 package?
The NL27WZ16MU3TCG in the UDFN6 1.0×1.0 mm package has a junction-to-ambient thermal resistance (θJA) of 154 °C/W, measured per JESD51-7 on an FR4 board with minimum pad spacing and no airflow. This value is listed in the Maximum Ratings table (page 3) and supports continuous operation up to +125 °C ambient when properly mounted.
Can the NL27WZ16MU3TCG replace the NL27WZ16MU1TCG or NL27WZ16MU2TCG in a design?
Yes-the NL27WZ16MU3TCG is functionally identical to NL27WZ16MU1TCG and NL27WZ16MU2TCG, differing only in mechanical package dimensions (1.0×1.0 mm vs. 1.45×1.0 mm vs. 1.2×1.0 mm). All share identical pinout, electrical specs, and thermal performance. Pin compatibility is confirmed in Figure 2 (page 2) and the Ordering Information table (page 6) of the datasheet.
Is the NL27WZ16MU3TCG qualified for automotive applications?
The NL27WZ16MU3TCG itself is standard-grade; however, the same die is offered in AEC-Q100 qualified variants with "−Q" suffix (e.g., NL27WZ16MU3TCG-Q). These Q-suffix parts undergo additional stress testing and PPAP documentation per AEC-Q100 Grade 1 (−40 °C to +125 °C), making them suitable for automotive body electronics where full qualification is mandated.
