Product details
Overview
74HCT1G14GW-Q100 from Nexperia is a single-channel inverting Schmitt trigger logic gate qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5 V), 5.0 V nominal supply, and 17 ns typical propagation delay (CL = 50 pF). It enables clean signal conditioning in noisy engine control and body electronics interfaces.
For engineers reviewing the 74HCT1G14GW-Q100 datasheet, 74HCT1G14GW-Q100 pinout, 74HCT1G14GW-Q100 application, or 74HCT1G14GW-Q100 equivalent, this page delivers verified pin functions, automotive-grade thermal and ESD specs (HBM >2000 V, CDM >1000 V), Schmitt hysteresis values (VH = 0.4–0.9 V), and real-world oscillator and waveform-shaping use cases.
Technical Context
This device implements a single CMOS inverter with Schmitt-trigger input circuitry that provides defined switching thresholds (VT+ = 1.4–2.1 V, VT− = 0.6–1.4 V at VCC = 4.5–5.5 V) and 0.4–0.9 V hysteresis to reject slow-rising noise on sensor or switch inputs. Its TTL-level input compatibility ensures direct interfacing with legacy microcontrollers and discrete logic without level-shifting.
Designed for automotive environments, it features clamp diodes on all inputs enabling current-limited overvoltage tolerance, symmetrical output drive (±2.0 mA at VCC = 4.5 V), and latch-up immunity exceeding 100 mA per JESD78 Class II Level B - critical for under-hood ECU reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Inverting Schmitt trigger - converts slow/noisy analog-like inputs into clean digital outputs with jitter-free edges. |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard automotive 5 V rail with ±10% tolerance; supports operation across full Grade 1 temperature range. |
| Input Thresholds (VCC = 4.5 V) | VT+ = 1.2–2.0 V, VT− = 0.4–1.2 V - provides 0.4–0.9 V hysteresis to suppress contact bounce or EMI-induced false triggering. |
| Propagation Delay | 17 ns typ (A→Y, VCC = 4.5 V, CL = 50 pF) - enables reliable timing in relaxation oscillators and pulse edge sharpening up to ~30 MHz. |
| Output Drive Strength | ±2.0 mA (VOH/VOL at VCC = 4.5 V) - sufficient to directly drive small capacitive loads or fan-out to multiple 74HCT inputs without buffering. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - exceeds AEC-Q100 requirements for assembly and field reliability in automotive production lines. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1, validated for under-dash, powertrain, and lighting control modules. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package, 5-lead, 1.25 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Not connected (n.c.) | No internal connection; must be left floating or grounded - no routing required. |
| 2 | Data input (A) | TTL-compatible input accepting 0–5.5 V; includes clamp diodes for overvoltage protection when used with series current-limiting resistors. |
| 3 | Ground (GND) | Reference 0 V return path; must be low-impedance and decoupled near VCC pin for stable Schmitt operation. |
| 4 | Data output (Y) | Inverted, rail-to-rail CMOS output; drives capacitive loads ≤50 pF within specified tpd; supports fan-out of ≥10 74HCT loads. |
| 5 | Supply voltage (VCC) | Positive supply rail (4.5–5.5 V); requires local 100 nF ceramic decoupling capacitor placed adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling, humidity, and vibration stress testing. |
| TTL-level input compatibility | Accepts standard 5 V TTL logic levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V), eliminating need for external level shifters in mixed-logic systems. |
| Schmitt-trigger hysteresis | 0.4–0.9 V window (VCC = 4.5–5.5 V) rejects noise on mechanical switch inputs, analog sensor signals, or long PCB traces. |
| Symmetrical output drive | ±2.0 mA output capability ensures matched rise/fall times and minimal duty-cycle distortion in oscillator applications. |
| Input clamp diodes | Enable safe interface to voltages up to VCC + 0.5 V using series current-limiting resistors - critical for battery-sensed or LIN-bus auxiliary signals. |
Applications
| Engine Control Unit (ECU) Switch Debouncing | Automotive Body Control Module (BCM) Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverting Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC1G14GW-Q100 | CMOS-level inputs (VIH = 3.5 V min at VCC = 4.5 V); wider 2.0–6.0 V supply range; slightly higher propagation delay (25 ns typ at VCC = 4.5 V). | Requires higher input voltage for logic HIGH; better suited for mixed-voltage systems with 3.3 V or 5 V domains. | Select when interfacing with CMOS microcontrollers or when wider supply flexibility is needed over TTL compatibility. |
| SN74LVC1G14DBVR | Lower VCC range (1.65–5.5 V); LVC logic family; 3.5 ns typ tpd at VCC = 3.3 V; not AEC-Q100 qualified. | Lacks automotive qualification; unsuitable for safety-critical or under-hood placement without additional validation. | Choose only for non-automotive industrial or consumer designs requiring faster speed and lower voltage operation. |

FAQ
What is the maximum recommended operating voltage for 74HCT1G14GW-Q100?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V per AEC-Q100 qualification. Operation above 5.5 V voids automotive qualification and risks parametric shift or accelerated wear-out, even if functional at room temperature.
Can Pin 1 (n.c.) be tied to GND or VCC?
No - Pin 1 is internally unconnected and must remain floating or be left unpopulated on the PCB. Connecting it to GND or VCC introduces parasitic coupling paths that may degrade noise immunity or cause unexpected current leakage, especially at high temperature.
How does the Schmitt hysteresis behave across temperature and supply voltage?
At VCC = 4.5 V, VT+ ranges from 1.2 V (min) to 2.0 V (max) and VT− from 0.4 V (min) to 1.2 V (max) across -40 °C to +125 °C, yielding VH = 0.4–0.9 V. Hysteresis widens slightly at higher VCC (up to 1.6 V at VCC = 6.0 V) but is guaranteed stable across full automotive temperature range.
Is this device suitable for driving a 100 pF capacitive load?
No - the datasheet specifies timing and drive performance only up to 50 pF (CL). Driving 100 pF increases propagation delay beyond specification (e.g., >30 ns), risks output overshoot/ringing, and may exceed dynamic power limits. Use a buffer stage or reduce trace capacitance to stay within rated CL.
