Product details
Overview
74AHC1G14GW-Q100 from Nexperia is a single-channel automotive-grade Schmitt-trigger inverter with CMOS input thresholds, 2.0 V to 5.5 V supply range, overvoltage-tolerant inputs (up to 5.5 V), and operation from −40 °C to +125 °C. It functions as a noise-immune signal conditioner in automotive sensor interface and power-on reset circuits.
For engineers reviewing the 74AHC1G14GW-Q100 datasheet, 74AHC1G14GW-Q100 pinout, 74AHC1G14GW-Q100 application, or 74AHC1G14GW-Q100 equivalent, key selection criteria include hysteresis voltage (0.45–1.6 V), propagation delay (1.0–16.5 ns), input threshold symmetry, AEC-Q100 Grade 1 qualification, and TSSOP5 package compatibility with high-density PCB layouts.
Technical Context
This device implements a single inverting Schmitt trigger with defined positive-going (VT+) and negative-going (VT−) input thresholds-e.g., VT+ = 3.85 V and VT− = 1.65 V at VCC = 5.5 V-enabling robust waveform shaping in noisy environments. Its overvoltage-tolerant inputs allow interfacing between 3.3 V logic and 5 V systems without level shifters.
The AHC logic family ensures CMOS-compatible switching levels and low static current (≤40 μA at VCC = 5.5 V), while symmetrical output drive (±8 mA at VCC = 4.5 V) supports clean rail-to-rail transitions. Dynamic performance is characterized by propagation delay (tpd) and power dissipation capacitance (CPD = 12 pF), directly usable for timing budgeting and dynamic power estimation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Inverting Schmitt trigger with hysteresis; rejects noise on slow-rising/falling signals and enables stable oscillation in relaxation circuits. |
| Supply Voltage Range | 2.0 V to 5.5 V; supports dual-rail mixed-voltage designs including 3.3 V and 5 V automotive subsystems. |
| Hysteresis Voltage (VH) | 0.45 V to 1.6 V (VCC = 5.5 V); provides ≥1.2 V noise margin between switching thresholds for reliable edge detection. |
| Propagation Delay (tpd) | 1.0–16.5 ns (CL = 15–50 pF, VCC = 3.0–5.5 V); enables timing-critical applications such as clock conditioning and debounce up to ~50 MHz. |
| Output Drive Strength | ±8 mA (VOH/VOL at VCC = 4.5 V); sufficient to drive multiple standard CMOS inputs or small capacitive loads without buffering. |
| AEC-Q100 Qualification | Grade 1 (−40 °C to +125 °C); certified for engine control units, body electronics, and ADAS domain controllers requiring automotive reliability. |
| Input Overvoltage Tolerance | 5.5 V absolute max regardless of VCC; permits direct connection to 5 V buses even when powered from 3.3 V, eliminating external clamping diodes. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm pitch, exposed pad not present, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Not connected (n.c.) | No internal bond; must be left floating or grounded per layout best practice-no electrical function or routing required. |
| 2 | Data input (A) | Schmitt-trigger input accepting 0–5.5 V; tolerant of slow edges and EMI; drives internal inverter stage with hysteresis. |
| 3 | Ground (GND) | Reference node for all I/O and supply; requires low-inductance connection to PCB ground plane to maintain noise immunity. |
| 4 | Data output (Y) | Inverted, buffered output with rail-to-rail swing; capable of sourcing/sinking ±8 mA into capacitive or resistive loads. |
| 5 | Supply voltage (VCC) | Primary power rail (2.0–5.5 V); decoupling capacitor (100 nF ceramic) required within 3 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 qualified for full automotive temperature range (−40 °C to +125 °C), enabling use in powertrain and chassis modules. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and minimizes duty-cycle distortion in oscillator applications. |
| High noise immunity | Typical hysteresis ≥1.2 V at 5.5 V supply provides >30% supply-margin rejection of coupled transients on sensor or switch inputs. |
| CMOS low-power operation | ICC ≤ 40 μA at VCC = 5.5 V and Tamb = +125 °C enables always-on monitoring in battery-sensitive modules like door modules or seat controls. |
| ESD robustness | HBM >2000 V and CDM >1000 V meet stringent automotive board-level ESD requirements without external protection components. |
Applications
| Engine Control Unit (ECU) Reset Circuit | Body Control Module (BCM) Switch Debounce |
|---|---|
Use Scenario: Clean power-on reset signal generation using RC network feeding into Schmitt trigger input. IC Role / Device Role / Timing Role: Converts noisy, slowly rising VCC ramp into sharp, jitter-free reset pulse with defined assertion time.

IC Role / Device Role / Timing Role: Input signal conditioner that filters bounce and transients before microcontroller GPIO sampling. Use Value: Provides deterministic 10–100 μs debounce window via RC time constant; avoids firmware-based polling or timer overhead. |

IC Role / Device Role / Timing Role: Noise-rejecting front-end buffer converting slow-moving analog-derived logic signals into clean digital edges. Use Value: Improves signal integrity in high-noise motor drive environment; reduces false triggering in torque feedback path. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G14GW-Q100 | TTL input thresholds (VIH ≈ 2.0 V), narrower supply range (4.5–5.5 V), identical package and AEC-Q100 Grade 1 rating. | Better suited for legacy 5 V-only systems where input compatibility with TTL logic families is required. | Select when interfacing with older 5 V microcontrollers or ASICs lacking CMOS-compatible input thresholds. |
| SN74LVC1G14DRYR | Industrial-grade (not AEC-Q100), wider supply (1.65–5.5 V), lower ICC (≤10 μA), same SOT-553 (TSSOP5) footprint. | Lacks automotive qualification; suitable for non-safety-critical infotainment or telematics modules operating below 125 °C. | Choose for cost-sensitive, non-automotive applications needing identical pinout but no AEC-Q100 compliance. |
Compared with 74AHCT1G14GW-Q100, the 74AHC1G14GW-Q100 offers broader supply flexibility and CMOS input compatibility; versus SN74LVC1G14DRYR, it trades ultra-low ICC for guaranteed automotive reliability and higher temperature operation.

FAQ
Is 74AHC1G14GW-Q100 pin-compatible with non-automotive variants like 74AHC1G14GW?
Yes-74AHC1G14GW-Q100 shares identical pinout, package (SOT353-1), and electrical behavior with industrial-grade 74AHC1G14GW. The "-Q100" suffix denotes AEC-Q100 qualification and extended temperature screening; no layout changes are needed for drop-in replacement in existing designs meeting automotive requirements.
Can this device operate reliably at 2.0 V supply in automotive applications?
Yes-74AHC1G14GW-Q100 is fully specified down to 2.0 V supply across −40 °C to +125 °C, with verified VIH/VIL thresholds, propagation delay (≤16.5 ns), and output drive (≥4 mA) at that voltage. This enables use in low-voltage subsystems such as 2.5 V CAN FD transceivers or battery-monitoring IC interfaces.
What is the maximum capacitive load this device can drive while maintaining specified tpd?
The datasheet specifies tpd up to CL = 50 pF at all supply voltages and temperatures. Driving >50 pF increases propagation delay nonlinearly and may degrade edge rate; for loads exceeding 50 pF, add a series resistor (10–33 Ω) near the output to damp ringing and maintain timing integrity without violating VOH/VOL specs.
Does the "n.c." pin (Pin 1) require any PCB layout treatment?
No-Pin 1 is internally unconnected and electrically inert. It may be left unconnected, tied to GND for mechanical stability, or routed to a test point; none affects functionality. Avoid routing high-speed signals adjacent to this pin to prevent unintended coupling, but no special keep-out or grounding is mandated.
