Product details
Overview
NLVVHC1G14DTT1G from onsemi is a single Schmitt-trigger inverter IC designed for signal conditioning and noise-immune digital logic inversion in low-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 mixed-supply interfacing - used in industrial sensor signal cleanup and microcontroller input debouncing.
For engineers reviewing the NLVVHC1G14DTT1G datasheet, pinout, applications, or equivalent options, key selection considerations include its Schmitt-trigger hysteresis (0.3–1.6 V), IOFF partial power-down protection, ±8 mA drive capability at 3.0 V, SC-74A (SOT-25) 5-pin package, and AEC-Q100 qualification for automotive-grade reliability.
Technical Context
The NLVVHC1G14DTT1G implements a three-stage buffered output architecture that enhances noise immunity and ensures stable switching under noisy conditions. Its input structure tolerates up to 5.5 V regardless of VCC, enabling safe 5 V-to-3 V level translation without external components.
It integrates IOFF circuitry that disables I/O leakage when VCC = 0 V, preventing back-powering in partial power-down modes. The device exhibits defined hysteresis (VH = 0.3–1.6 V) with CMOS-compatible thresholds, distinguishing it from TTL-threshold variants like MC74VHC1GT14.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports wide-input rail operation across battery-powered and industrial 3.3 V/5 V systems. |
| tPD (Typ) | 4.0 ns at VCC = 5 V, CL = 15 pF - enables high-speed signal inversion in timing-critical edge-detection paths. |
| Input Thresholds | VT+ = 2.2–3.85 V, VT− = 0.9–1.65 V (CMOS-level) - provides robust noise margin (>0.3 V) for slow-rising signals like mechanical switch inputs. |
| I/O Overvoltage | Up to 5.5 V independent of VCC - allows direct connection to 5 V buses while powered from 3.3 V, eliminating level-shifters. |
| IOFF Protection | Active when VCC = 0 V - prevents current backflow into powered subsystems during hot-swap or partial shutdown. |
| Output Drive | ±8 mA at VCC = 3.0 V - sufficient to directly drive multiple standard CMOS inputs or small LEDs without buffering. |
| Operating Temp | −55 °C to +125 °C - qualified for extended industrial and automotive under-hood environments. |
Pinout & Package
Package: SC-74A (SOT-25), 5-pin, 3.0 mm × 1.5 mm × 0.95 mm body, 0.95 mm pitch, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - A | Input | Inverting logic input with Schmitt-trigger hysteresis; accepts 0–5.5 V regardless of VCC. |
| 2 - GND | Ground Reference | Primary return path for supply and signal currents; must be low-impedance for noise immunity. |
| 3 - NC | No Connect | Internally unconnected; must remain floating or tied to GND per layout best practices. |
| 4 - Y | Output | Inverted, buffered output with ±8 mA drive; overvoltage tolerant up to 5.5 V even at VCC = 0 V. |
| 5 - VCC | Supply Voltage | Positive supply rail (2.0–5.5 V); powers internal logic and enables IOFF behavior when at 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input with programmable hysteresis | Hysteresis voltage (VH) ranges from 0.3 V (2.0 V VCC) to 1.6 V (5.5 V VCC), rejecting noise on slow or noisy signals. |
| Overvoltage-tolerant I/O | Inputs and outputs withstand 5.5 V regardless of VCC value - enables seamless 5 V ↔ 3.3 V interface without external clamps. |
| IOFF partial power-down protection | Blocks current flow between I/O pins when VCC = 0 V - critical for system-level power sequencing and hot-plug safety. |
| High noise immunity via buffered output | Three-stage internal buffer isolates output from input transients, minimizing crosstalk and improving signal integrity. |
| AEC-Q100 Grade 1 qualification | Qualified for automotive applications (−40 °C to +125 °C ambient), including engine control and body electronics modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC1G14DFT2G | Same die, SC-88A (SOT-353) package - 2.1 mm × 1.25 mm, 0.65 mm pitch; slightly higher thermal resistance (377 °C/W vs. 320 °C/W). | Preferred for ultra-dense PCB layouts where footprint area is more constrained than height; less suitable for high-power-density thermal environments. | Select when board space is premium and thermal load is light; verify solder paste volume and reflow profile for smaller pad geometry. |
| SN74LVC1G14DBVR | Texas Instruments part; identical function but TTL-compatible thresholds (VT+ ≈ 1.7 V, VT− ≈ 0.5 V); 3.0 ns tPD at 3.3 V; different pinout (A/Y/VCC/GND/NC). | Better suited for legacy 3.3 V systems with marginal input rise times; lacks AEC-Q100 qualification and 5.5 V overvoltage tolerance. | Choose only for cost-sensitive non-automotive designs requiring faster propagation; avoid where 5 V interfacing or automotive qualification is required. |
Compared with MC74VHC1G14DFT2G, NLVVHC1G14DTT1G offers lower thermal resistance and automotive qualification in SC-74A; versus SN74LVC1G14DBVR, it provides wider voltage tolerance and guaranteed hysteresis stability across temperature, at the cost of slightly longer propagation delay.

FAQ
What is the input hysteresis voltage range for NLVVHC1G14DTT1G across its full operating voltage?
The NLVVHC1G14DTT1G exhibits a hysteresis voltage (VH) ranging from 0.30 V at VCC = 2.0 V to 1.60 V at VCC = 5.5 V, measured across −55 °C to +125 °C. This hysteresis is intrinsic to its Schmitt-trigger design and ensures consistent noise rejection regardless of supply voltage or temperature - a key specification confirmed in the DC Electrical Characteristics table of the official onsemi datasheet (Rev. 30, Jan 2026).
Does NLVVHC1G14DTT1G support 5 V input signals while powered from 3.3 V?
Yes, NLVVHC1G14DTT1G supports 5 V input signals while powered from 3.3 V. Its inputs are overvoltage tolerant up to 5.5 V independent of VCC, as verified in the Maximum Ratings and Recommended Operating Conditions sections of the datasheet. This eliminates the need for external level-shifting components when interfacing 5 V sensors or legacy logic to 3.3 V microcontrollers.
Is NLVVHC1G14DTT1G pin-compatible with SN74LVC1G14?
No, NLVVHC1G14DTT1G is not pin-compatible with SN74LVC1G14. While both are single Schmitt-trigger inverters, NLVVHC1G14DTT1G uses SC-74A (SOT-25) pinout: Pin 1 = A, Pin 2 = GND, Pin 3 = NC, Pin 4 = Y, Pin 5 = VCC. SN74LVC1G14DBVR uses SOT-23-5: Pin 1 = A, Pin 2 = GND, Pin 3 = Y, Pin 4 = VCC, Pin 5 = NC - a different terminal assignment confirmed in TI's SLRS208F datasheet.
What is the maximum output drive strength of NLVVHC1G14DTT1G at 3.0 V supply?
At VCC = 3.0 V, NLVVHC1G14DTT1G delivers ±8 mA output drive strength (IOL/IOH), as specified in the DC Electrical Characteristics table for the MC74VHC1G14 variant. This is sufficient to drive 10 standard CMOS loads (1 TTL unit load = 0.8 mA) or directly interface with small indicator LEDs using appropriate current-limiting resistors.
Does NLVVHC1G14DTT1G include IOFF functionality, and how does it behave during power-down?
Yes, NLVVHC1G14DTT1G includes IOFF functionality. When VCC = 0 V, the IOFF circuit actively disables I/O paths, limiting input/output leakage current to ≤10 µA (max) - verified in the DC Electrical Characteristics table. This prevents back-powering of powered subsystems during partial power-down or hot-insertion scenarios, a critical feature for system-level power sequencing integrity.
