Product details
Overview
NL27WZ14MU1TCG from onsemi is a dual Schmitt-trigger inverter IC operating from 1.65 V to 5.5 V, delivering 3.2 ns propagation delay at 5 V, ±32 mA output drive capability, and overvoltage-tolerant inputs/outputs up to 5.5 V. It serves as a noise-immune signal conditioning and level-shifting element in low-power digital interfaces, sensor signal preprocessing, and microcontroller input debouncing circuits.
For engineers reviewing the NL27WZ14MU1TCG datasheet, pinout, applications, or equivalent options, key selection considerations include its UDFN6 (1.45 × 1.0 mm, 0.5 mm pitch) package, −55 °C to +125 °C operating range, IOFF partial power-down support, Schmitt-trigger hysteresis (0.7 V min at 5.5 V), and AEC-Q100 qualification for automotive use.
Technical Context
The NL27WZ14MU1TCG integrates two independent Schmitt-trigger inverters with rail-to-rail input tolerance and active-drive outputs capable of sinking 32 mA at 4.5 V. Its hysteresis voltage (VH) ranges from 0.1 V at 1.65 V to 1.7 V at 5.5 V, enabling robust noise rejection in noisy industrial environments.
It features IOFF circuitry that disables output leakage during power-down states, supporting live-insertion and partial system shutdown. The device complies with AEC-Q100 Grade 1 (−40 °C to +125 °C) when ordered with the −Q suffix, though NL27WZ14MU1TCG itself is standard-grade per datasheet ordering table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Propagation Delay (tPLH/tPHL) | 3.2 ns typical at VCC = 5 V, CL = 15 pF - Supports high-speed signal inversion in timing-critical paths. |
| Output Drive Strength | Sink 32 mA at 4.5 V - Drives multiple standard TTL/CMOS loads or small LEDs directly. |
| Input Hysteresis (VH) | 0.7 V minimum at VCC = 5.5 V - Rejects up to ±350 mV of noise on slow-rising/falling signals (e.g., mechanical switches). |
| IOFF Leakage Current | ≤10 µA at VCC = 0 V - Prevents back-driving of powered sections during partial power-down. |
| Operating Temperature | −55 °C to +125 °C - Suitable for under-hood automotive, industrial control, and extended-temperature embedded systems. |
| ESD Rating (HBM) | 2000 V - Provides robust handling margin during board assembly and field service. |
Pinout & Package
NL27WZ14MU1TCG uses the UDFN6 package (1.45 mm × 1.0 mm, 0.5 mm pitch, 0.45–0.55 mm height), with exposed copper pad for thermal enhancement. Pin 1 is marked by a rotated microdot (90° clockwise) per case 517AQ.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 (Output) | Inverted output of first inverter channel; rail-to-rail CMOS-compatible swing. |
| 2 | A2 (Input) | Second Schmitt-trigger input; accepts 0–5.5 V regardless of VCC. |
| 3 | A1 (Input) | First Schmitt-trigger input; enables independent noise-immune signal conditioning. |
| 4 | Y2 (Output) | Inverted output of second inverter channel; electrically isolated from Y1. |
| 5 | GND | Digital ground reference; must be connected to system ground plane for stable operation. |
| 6 | VCC | Positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 2 mm. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G14DBVR | Same 6-pin SOT-23 package; 3.5 ns tPD at 3.3 V; lower max VCC (3.6 V); no IOFF. | Limited to ≤3.6 V systems; lacks partial power-down protection for hot-swap designs. | Select when footprint compatibility with SOT-23 is mandatory and supply stays ≤3.6 V. |
| MC74VHC14DT | SOIC-14 package; 7.5 ns tPD at 5 V; higher drive (±8 mA); wider temp range (−55 °C to +125 °C). | Requires PCB redesign due to larger SOIC footprint; better for legacy through-hole or high-reliability mil-aero use. | Select when board space allows SOIC and higher hysteresis stability across extreme temperatures is prioritized. |
Compared with SN74LVC2G14DBVR and MC74VHC14DT, NL27WZ14MU1TCG uniquely combines UDFN6 miniaturization, 5.5 V operation, IOFF, and −55 °C to +125 °C rating-making it optimal for space-constrained, wide-supply, and partial-power-down automotive/industrial modules.

FAQ
What is the maximum input voltage the NL27WZ14MU1TCG can tolerate?
The NL27WZ14MU1TCG supports DC input voltages from −0.5 V to +6.5 V, independent of VCC. This overvoltage tolerance up to 5.5 V (per recommended conditions) allows safe interfacing with higher-voltage signals-such as 5 V sensor outputs-into 1.8 V or 3.3 V systems without external clamping, reducing BOM count and layout complexity in the NL27WZ14MU1TCG design.
Does the NL27WZ14MU1TCG support partial power-down mode?
Yes, the NL27WZ14MU1TCG features IOFF circuitry that limits output leakage current to ≤10 µA when VCC = 0 V. This enables safe isolation of unpowered sections in multi-rail systems-critical for hot-swap modules and battery-backed subsystems-without risking back-current flow through the NL27WZ14MU1TCG outputs during power sequencing.
What is the typical propagation delay of the NL27WZ14MU1TCG at 3.3 V?
At VCC = 3.3 V, CL = 15 pF, and TA = 25 °C, the NL27WZ14MU1TCG exhibits a typical propagation delay (tPLH/tPHL) of 3.3 ns. This value is confirmed in the AC Electrical Characteristics table for the 3.0–3.6 V range, ensuring predictable timing margins in 3.3 V FPGA/CPU interface and clock-domain crossing circuits using the NL27WZ14MU1TCG.
Is the NL27WZ14MU1TCG qualified for automotive applications?
The base NL27WZ14MU1TCG is not AEC-Q100 qualified; however, the −Q suffix variant (e.g., NL27WZ14MU1TCG−Q) is explicitly rated for automotive use per AEC-Q100 Grade 1 (−40 °C to +125 °C) and PPAP-capable. Customers requiring automotive qualification must specify the −Q version-the NL27WZ14MU1TCG part number alone denotes the commercial-grade device.
What is the thermal resistance (θJA) of the NL27WZ14MU1TCG in its UDFN6 package?
The NL27WZ14MU1TCG in the UDFN6 (1.45 × 1.0 mm, 0.5P) 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 low θJA enables continuous operation at full output drive (32 mA) up to +85 °C ambient without derating, a key advantage over SC-88/SC-74 variants in thermally dense layouts using the NL27WZ14MU1TCG.
