Product details
Overview
74LVC1G14GV-Q100 from Nexperia is a single Schmitt-trigger inverter IC qualified to AEC-Q100 Grade 1 for automotive use, operating from −40 °C to +125 °C with supply voltage range 1.65 V to 5.5 V, ±24 mA output drive at 3.0 V, and IOFF circuitry enabling partial power-down mode. It interfaces across mixed 3.3 V/5 V systems and provides high noise immunity in signal conditioning applications.
For engineers reviewing the 74LVC1G14GV-Q100 datasheet, 74LVC1G14GV-Q100 pinout, 74LVC1G14GV-Q100 application, or 74LVC1G14GV-Q100 equivalent, key selection considerations include its Schmitt-trigger hysteresis (0.31 V min at 3.0 V), overvoltage-tolerant inputs (to 5.5 V), and SC-74A (SOT753) package compatibility with space-constrained automotive control modules.
Technical Context
This device implements a single CMOS inverter with Schmitt-trigger input thresholds-VT+ = 1.29 V and VT− = 0.88 V (min, 3.0 V supply)-enabling clean waveform shaping of slow or noisy signals. Its IOFF functionality disables outputs during power-down, preventing backflow current when VCC = 0 V.
It supports direct TTL-level interfacing and complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full 1.65–5.5 V supply range. Propagation delay is 0.7–7.0 ns depending on VCC, with typical 3.0 ns at 3.0–3.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 1 |
| Input Hysteresis (VH) | 0.31 V min at 3.0 V - rejects noise up to ±155 mV on input transitions, critical for reliable edge detection |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to directly drive LEDs, small relays, or fan-out to ≥10 LVC loads |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - prevents damaging backflow in hot-swap or partial-power-down systems |
| Propagation Delay | 0.7–7.0 ns - ensures sub-10 ns timing integrity in clockless relaxation oscillators and pulse shapers |
| ESD Robustness | HBM >2000 V, CDM >1000 V - meets automotive ESD requirements without external protection |
Pinout & Package
74LVC1G14GV-Q100 uses the SC-74A (SOT753) surface-mount package: plastic, 5-lead, body size 3.1 mm × 1.7 mm × 1.1 mm, with gull-wing leads and pin 1 indicator below marking code "V14".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - left unconnected; no routing or thermal tie required |
| 2 | A | Data input - accepts overvoltage-tolerant signals up to 5.5 V regardless of VCC |
| 3 | GND | Ground reference - must be low-impedance return path for both input and output currents |
| 4 | Y | Inverted output - Schmitt-triggered, rail-to-rail swing, capable of ±24 mA sink/source |
| 5 | VCC | Supply voltage - powers internal circuitry; IOFF activates automatically when VCC = 0 V |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including lifetime reliability testing |
| IOFF partial power-down | Outputs disabled with leakage <±2 μA when VCC = 0 V - eliminates backfeed in multi-rail systems |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V input signals independent of VCC - enables 5 V sensor interfacing into 3.3 V domains |
| Unlimited rise/fall times | Operates reliably with arbitrarily slow input edges - eliminates need for external RC filtering |
| High noise immunity | 0.31 V minimum hysteresis at 3.0 V - suppresses glitches from EMI, crosstalk, or long traces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G14GW-Q100 | TSSOP5 (SOT353-1) package; 1.25 mm body width; 0.65 mm lead pitch vs. SC-74A's 0.95 mm | Better thermal dissipation (250 mW Ptot vs. 250 mW derated above 85 °C); preferred for higher ambient temp zones | Select when board layout allows wider footprint and improved heat spreading is needed in engine bay modules |
| SN74LVC1G14DRYR | Non-automotive grade; rated −40 °C to +85 °C; identical electrical specs but lacks AEC-Q100 qualification | Not approved for safety-critical or under-hood automotive use; suitable for infotainment or ADAS non-safety subsystems | Choose only for cost-sensitive non-automotive designs or Tier-2 subsystems where AEC-Q100 is not mandated |
Compared with 74LVC1G14GW-Q100, the 74LVC1G14GV-Q100 offers smaller footprint and lower profile for tight-space applications, while SN74LVC1G14DRYR provides identical performance at lower cost where automotive qualification is unnecessary.

FAQ
What is the maximum supply voltage rating for the 74LVC1G14GV-Q100?
The absolute maximum supply voltage (VCC) for the 74LVC1G14GV-Q100 is +6.5 V, per IEC 60134 limiting values. However, recommended operation is strictly 1.65 V to 5.5 V. Exceeding 5.5 V risks permanent damage even if current limits are observed, and operation above this range voids AEC-Q100 qualification guarantees. Always maintain VCC within the recommended window for automotive reliability.
Does the 74LVC1G14GV-Q100 support true 5 V logic input levels when powered from 3.3 V?
Yes. The 74LVC1G14GV-Q100 features overvoltage-tolerant inputs rated to 5.5 V regardless of VCC level. When powered from 3.3 V, it correctly interprets 5 V TTL or CMOS inputs as HIGH without external level-shifting circuitry - a key enabler for mixed-voltage automotive subsystems such as connecting 5 V engine sensors to 3.3 V microcontrollers.
How does the IOFF function behave during system power sequencing?
The IOFF circuit in the 74LVC1G14GV-Q100 automatically disables the output stage when VCC drops to 0 V, limiting output leakage to ±2 μA max. This prevents backflow current from live buses (e.g., 5 V I²C lines) into a powered-down domain, protecting downstream circuitry during controlled power-down sequences common in automotive gateway modules and domain controllers.
What is the typical propagation delay of the 74LVC1G14GV-Q100 at 3.3 V supply?
At VCC = 3.3 V and Tamb = 25 °C, the typical propagation delay (tpd) of the 74LVC1G14GV-Q100 is 3.0 ns, with a maximum of 5.5 ns over −40 °C to +125 °C. This value applies to both tPLH and tPHL transitions and is measured under standard load conditions (CL = 50 pF, RL = 500 Ω), making it suitable for sub-100 MHz edge-sensitive timing functions.
Can the 74LVC1G14GV-Q100 be used to build a relaxation oscillator?
Yes. The 74LVC1G14GV-Q100 is explicitly validated for relaxation oscillator use (see Fig. 10 in datasheet). With a single external resistor and capacitor, it generates stable square waves - frequency determined by R, C, and its intrinsic VT+ (1.29 V min) and VT− (0.88 V min) thresholds at 3.0 V. This replaces dedicated oscillator ICs in cost- and space-constrained automotive timing applications.
