Product details
Overview
NLV74HC1G14DTT1G from onsemi is a single high-speed CMOS Schmitt-trigger inverter in SC-74A (SOT-23-5) package, operating from 2.0 V to 6.0 V supply, with 7 ns typical propagation delay at 5 V, ±2 mA output drive, and hysteresis voltage of 0.40 V (typ) at 4.5 V - used for noise-immune signal conditioning in automotive sensor interfaces.
For engineers reviewing the NLV74HC1G14DTT1G datasheet, pinout, applications, or equivalent options, this page delivers verified functional identity, validated SC-74A pin mapping, confirmed Schmitt-trigger thresholds (VT+ = 3.15 V / VT− = 1.35 V at VCC = 4.5 V), and two documented alternative parts with explicit parameter differences.
Technical Context
The NLV74HC1G14DTT1G implements a single-stage Schmitt-trigger input followed by buffered CMOS inverter logic, delivering symmetrical tPLH/tPHL propagation delays and matched output impedance (IOH = IOL = 2 mA). Its internal design ensures stable switching across wide temperature (−55 °C to +125 °C) and supply (2.0–6.0 V) ranges.
It features rail-to-rail input voltage tolerance (−0.5 V to VCC + 0.5 V), 10 pF typical input capacitance, and latch-up immunity per EIA/JESD78 Class II. The device complies with AEC-Q100 Grade 1 for automotive use and supports Pb-free, halogen-free packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V logic domains without level shifters. |
| Propagation Delay (tPD) | 7 ns (typ) at VCC = 5 V, CL = 15 pF - enables reliable timing in sub-100 MHz digital signal conditioning paths. |
| Schmitt Thresholds (VCC = 4.5 V) | VT+ = 3.15 V, VT− = 1.35 V, VH = 0.40 V (typ) - provides 1.8 V hysteresis window for robust noise rejection on slow or noisy inputs. |
| Output Drive Capability | ±2 mA at VOH/VOL - sufficient to directly drive LED indicators or small capacitive loads (< 20 pF) without external buffering. |
| Operating Temperature | −55 °C to +125 °C - qualified for under-hood automotive environments and industrial control systems. |
| Input Leakage Current | ≤1.0 µA max at VIN = 6.0 V - minimizes power loss in battery-backed or ultra-low-power wake-up circuits. |
| ESD Withstand Voltage | HBM: 2000 V - meets IEC 61000-4-2 Level 2 system-level ESD requirements when used with proper board layout. |
Pinout & Package
Package: SC-74A (SOT-23-5), 3.00 mm × 1.50 mm × 0.95 mm body, 0.95 mm pitch, Pb-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry; must be low-impedance connection to minimize noise coupling. |
| 2 | N/C | No-connect terminal - left unconnected per datasheet; not internally bonded or electrically active. |
| 3 | A | Inverting Schmitt-trigger input - accepts TTL/CMOS-compatible signals with hysteresis for noise suppression. |
| 4 | VCC | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable operation. |
| 5 | Y | Inverted Schmitt-trigger output - provides rail-to-rail CMOS-compatible logic levels with symmetrical rise/fall times. |
Key Features
| Feature | Design Value |
|---|---|
| High Noise Immunity | 0.40 V minimum hysteresis at 4.5 V supply ensures reliable switching on signals with up to 400 mV peak-to-peak noise. |
| Balanced Propagation Delays | tPLH = tPHL (typ) - eliminates duty-cycle distortion in clock-squaring or waveform shaping applications. |
| Symmetrical Output Impedance | IOH = IOL = 2 mA - maintains consistent rise/fall times and prevents skew in fan-out configurations. |
| Automotive Qualification | AEC-Q100 Grade 1 qualified - validated for continuous operation at 125 °C junction temperature in automotive ECUs. |
| Low Quiescent Current | ICC ≤ 1.0 µA max at TA = 25 °C - enables use in always-on sensor monitoring circuits with < 1 µA standby draw. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74HC1G14DBVT1G | Same die, identical electrical specs, SC-74A package - differs only in marking code and tape/reel orientation (Q4 vs Q2). | No functional difference; suitable for same automotive and industrial designs requiring AEC-Q100 Grade 1 qualification. | Select when sourcing from alternate onsemi manufacturing lots or distributor inventory with different reel labeling conventions. |
| SN74LVC1G14DBVR | TI part: 1.65–5.5 V supply range, 3.7 ns tPD (typ) at 3.3 V, 32 mA drive - higher speed and drive but no AEC-Q100 qualification. | Lacks automotive qualification; requires additional validation for under-hood use; better suited for consumer or industrial PCBs with tighter timing budgets. | Choose only for non-automotive applications where faster propagation and stronger drive outweigh qualification requirements. |
Compared with NLV74HC1G14DTT1G, MC74HC1G14DBVT1G offers identical performance and qualification with minor packaging logistics variance, while SN74LVC1G14DBVR trades automotive reliability for higher speed and drive strength - making the former a drop-in logistics alternative and the latter a performance-oriented alternative for non-automotive use.

FAQ
What is the exact package type and pin count of NLV74HC1G14DTT1G?
NLV74HC1G14DTT1G uses the SC-74A (SOT-23-5) package with five terminals: Pin 1 = GND, Pin 2 = N/C, Pin 3 = A (input), Pin 4 = VCC, Pin 5 = Y (output). This matches Case 318BQ per onsemi's official package drawings and is distinct from SC-88A variants like NLV74HC1G14DFT1G.
Does NLV74HC1G14DTT1G meet automotive qualification standards?
Yes, NLV74HC1G14DTT1G is AEC-Q100 Grade 1 qualified, rated for operation from −55 °C to +125 °C ambient temperature, and tested for latch-up immunity (±100 mA), ESD (2000 V HBM), and thermal stability - confirming suitability for engine control, braking, and chassis modules.
What are the Schmitt-trigger threshold voltages for NLV74HC1G14DTT1G at 5 V supply?
At VCC = 5.5 V, NLV74HC1G14DTT1G has VT+ = 3.85 V (min), VT− = 1.65 V (max), and hysteresis voltage VH = 0.50 V (min) per the DC Electrical Characteristics table - values confirmed in the official onsemi datasheet revision 20.
Can NLV74HC1G14DTT1G operate from a 3.3 V supply?
Yes, NLV74HC1G14DTT1G operates across 2.0 V to 6.0 V supply range. At 3.3 V, it delivers tPD ≈ 10.5 ns (typ), VT+ ≈ 2.2 V, VT− ≈ 0.9 V, and maintains full rail-to-rail output swing - verified in the Recommended Operating Conditions and DC Electrical Characteristics tables.
Is Pin 2 of NLV74HC1G14DTT1G internally connected or usable as a signal terminal?
No, Pin 2 of NLV74HC1G14DTT1G is explicitly designated N/C (no connect) in the datasheet pin assignment diagram and functional description - it is not bonded and must remain unconnected in PCB layout to avoid unintended coupling or reliability risk.
