Product details
Overview
NLVVHC1G14DFT2G from onsemi is a single Schmitt-trigger inverter IC designed for level-shifting and noise-immune signal conditioning in mixed-voltage systems. It operates from 2.0 V to 5.5 V, delivers 4.0 ns typical propagation delay at 5 V, features CMOS-level input thresholds (VT+ = 2.2–3.85 V, VT− = 0.9–1.65 V), and supports 5.5 V overvoltage-tolerant I/O for interfacing 5 V logic to 3 V circuits.
For engineers reviewing the NLVVHC1G14DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include hysteresis voltage (0.30–1.60 V), IOFF partial power-down support, ±8 mA drive capability at 3.0 V, SC-88A package compatibility, and AEC-Q100 qualification for automotive use cases.
Technical Context
The NLVVHC1G14DFT2G implements a three-stage buffered output architecture that enhances noise immunity and ensures stable switching in electrically noisy environments. Its input structure tolerates up to 5.5 V regardless of VCC, enabling safe 5 V-to-3 V bidirectional interfacing without external clamping.
It incorporates IOFF circuitry that disables output leakage when VCC = 0 V, supporting hot-insertion and partial power-down modes. The device is specified across −55 °C to +125 °C and meets AEC-Q100 Grade 1 requirements for automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - Enables operation across industrial, automotive, and battery-powered 3.3 V/5 V systems. |
| Propagation Delay | 4.0 ns (typ) at 5 V, CL = 15 pF - Supports high-speed digital signal conditioning in timing-critical paths. |
| Hysteresis Voltage | 0.30–1.60 V - Provides robust noise margin against EMI-induced false triggering in sensor or switch inputs. |
| IOFF Leakage | <10 µA at VCC = 0 V - Prevents back-powering and bus contention during system sleep or hot-swap events. |
| Output Drive | ±8 mA at 3.0 V - Sufficient to directly drive multiple 74LVC inputs or small capacitive loads without buffering. |
| Input Overvoltage | Up to 5.5 V independent of VCC - Eliminates need for external level-shifters when connecting legacy 5 V peripherals. |
| Operating Temp | −55 °C to +125 °C - Qualified for under-hood automotive, industrial control, and extended-temperature embedded designs. |
Pinout & Package
Package: SC-88A (Case 419A), 5-pin surface-mount package with 0.65 mm pitch, 2.1 mm × 1.25 mm footprint, and 0.95 mm max height - optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must be left floating or tied to GND per layout best practice - no electrical function. |
| 2 | Input (A) | Inverting Schmitt-trigger input; accepts 0–5.5 V signals regardless of VCC - enables mixed-supply interface. |
| 3 | GND | Ground reference for all internal circuitry and I/O - requires low-impedance connection to minimize ground bounce. |
| 4 | Output (Y) | Inverted, buffered output with hysteresis; drives high/low states with ±8 mA capability at 3 V. |
| 5 | VCC | Positive supply rail; powers internal logic and output stage - decoupling capacitor (0.1 µF) required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| CMOS-level Schmitt thresholds | VT+ = 2.2–3.85 V / VT− = 0.9–1.65 V at VCC = 3.0–5.5 V - ensures reliable switching with slow-rising analog or mechanical switch inputs. |
| Overvoltage-tolerant I/O | Inputs and outputs withstand 5.5 V even at VCC = 2.0 V - eliminates external protection diodes in 3.3 V microcontroller GPIO interfacing. |
| IOFF partial power-down | Output enters high-impedance state with <10 µA leakage when VCC = 0 V - prevents backfeeding in multi-rail systems during power sequencing. |
| AEC-Q100 qualified | Grade 1 (−40 °C to +125 °C ambient) with PPAP capability - certified for automotive body electronics, infotainment, and ADAS subsystems. |
| Pb-free, RoHS-compliant | Meets JESD201A Class 2a whisker resistance and UL 94 V-0 flammability - suitable for consumer, industrial, and automotive end-equipment. |
Applications
| Motor Control Feedback | Automotive Sensor Interface |
|---|---|
Use Scenario: Conditioning Hall-effect or reed-switch signals from BLDC motor commutation sensors before feeding to MCU GPIO. IC Role / Device Role / Timing Role: Schmitt-trigger inverter provides hysteresis filtering to reject EMI from motor windings and ensure clean edge transitions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC1G14DBVT1G | Identical electrical specs; packaged in SC-74A (3.0 × 1.5 mm) instead of SC-88A (2.1 × 1.25 mm). | Requires larger PCB footprint but offers higher thermal resistance margin (JA = 320 °C/W vs. 377 °C/W). | Select when board layout allows larger package and thermal derating is prioritized over miniaturization. |
| SN74LVC1G14DBVR | Lower VCC range (1.65–5.5 V); 3.7 ns tPD at 3.3 V; lacks AEC-Q100 qualification and IOFF support. | Suitable for commercial-grade 3.3 V systems only; not rated for automotive or hot-swap use. | Choose for cost-sensitive consumer applications where AEC-Q100 and partial power-down are unnecessary. |
Compared with MC74VHC1G14DBVT1G, NLVVHC1G14DFT2G saves 42% board area but trades 57 °C/W higher thermal resistance; versus SN74LVC1G14DBVR, it adds automotive qualification and IOFF at the cost of slightly higher propagation delay at 3.3 V.

FAQ
What is the input threshold behavior of the NLVVHC1G14DFT2G?
The NLVVHC1G14DFT2G features CMOS-level Schmitt-trigger input thresholds: VT+ ranges from 2.2 V to 3.85 V and VT− from 0.9 V to 1.65 V depending on VCC (3.0–5.5 V). This hysteresis (0.30–1.60 V) rejects noise on slow-rising signals, making NLVVHC1G14DFT2G ideal for switch debouncing and sensor signal conditioning without external RC networks.
Does the NLVVHC1G14DFT2G support partial power-down operation?
Yes, the NLVVHC1G14DFT2G includes IOFF circuitry that places the output in high-impedance state with leakage current <10 µA when VCC = 0 V. This feature prevents back-driving and bus contention during hot-swap or multi-rail power sequencing - a critical capability confirmed in the datasheet's DC Electrical Characteristics table for NLVVHC1G14DFT2G.
Can the NLVVHC1G14DFT2G interface 5 V signals to a 3.3 V microcontroller?
Yes, the NLVVHC1G14DFT2G inputs tolerate up to 5.5 V regardless of VCC level, allowing direct connection of 5 V sensor or peripheral outputs to its A pin while powered from a 3.3 V rail. This overvoltage tolerance eliminates level-shifter ICs or resistor dividers - a verified capability documented in both the "Features" and "Maximum Ratings" sections for NLVVHC1G14DFT2G.
What is the operating temperature range for the NLVVHC1G14DFT2G?
The NLVVHC1G14DFT2G is rated for −55 °C to +125 °C junction temperature and is AEC-Q100 Grade 1 qualified. This extended range supports under-hood automotive applications, industrial control cabinets, and outdoor infrastructure deployments - explicitly confirmed in the "Recommended Operating Conditions" table for NLVVHC1G14DFT2G.
Which package does the NLVVHC1G14DFT2G use, and what are its dimensions?
The NLVVHC1G14DFT2G uses the SC-88A (also known as SOT-353) package: 2.1 mm × 1.25 mm footprint, 0.65 mm pin pitch, and 0.95 mm maximum height. Pin 1 orientation is marked with a dot, and the package is Pb-free and RoHS-compliant - details confirmed in the "Ordering Information" and "Package Dimensions" sections of the NLVVHC1G14DFT2G datasheet.
