Product details
Overview
74AHCT14D-Q100,118 from Nexperia is an automotive-grade hex inverting Schmitt trigger IC with TTL-compatible inputs, 14-pin SO14 package, -40 °C to +125 °C operating range, 4.5–5.5 V supply, and 4.0–9.0 ns propagation delay (CL = 50 pF). It provides noise-immune signal conditioning for digital interface level-shifting in engine control units and body electronics.
For engineers reviewing the 74AHCT14D-Q100,118 datasheet, 74AHCT14D-Q100,118 pinout, 74AHCT14D-Q100,118 application, or 74AHCT14D-Q100,118 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.4–1.5 V), overvoltage-tolerant inputs (up to 5.5 V), AEC-Q100 Grade 1 qualification, and SO14 thermal derating (10.1 mW/K above 100 °C).
Technical Context
This device implements six independent inverting Schmitt-trigger buffers with TTL-level input thresholds (VT+ = 1.9–2.1 V, VT− = 0.5–0.6 V at VCC = 4.5–5.5 V) and CMOS-compatible outputs. Its hysteresis enables reliable waveform shaping of slow or noisy signals in automotive sensor interfaces.
Each channel delivers rail-to-rail output swing, supports 8 mA sink/source drive strength, and maintains stable operation across full automotive temperature range with <2.0 μA ICC at VCC = 5.5 V and VI = VCC/GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V - Ensures compatibility with 5 V automotive logic rails and tolerance to battery transients. |
| Propagation Delay | 5.4–10.0 ns (CL = 50 pF) - Enables reliable timing in 50 MHz+ clock/data conditioning paths. |
| Hysteresis Voltage | 0.4–1.5 V - Provides robust noise margin against EMI in under-hood environments. |
| Input Thresholds | VT+ = 1.9–2.1 V, VT− = 0.5–0.6 V - Matches standard TTL logic levels for seamless interfacing. |
| Output Drive | ±8 mA - Sufficient to directly drive multiple 74-series inputs or small capacitive loads (<50 pF). |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets automotive system-level ESD immunity requirements. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - Qualified for powertrain and chassis control modules. |
Pinout & Package
SO14 plastic small outline package (SOT108-1), 14-lead, 3.9 mm body width, 1.27 mm lead pitch, with gull-wing leads and pin 1 index marker.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data Input (1A–6A) | TTL-level Schmitt-trigger inputs; tolerate up to 5.5 V regardless of VCC. |
| 2, 4, 6, 8, 10, 12 | Data Output (1Y–6Y) | Inverted CMOS outputs; rail-to-rail swing, ±8 mA drive capability. |
| 7 | GND | Ground reference (0 V); required for all internal logic and I/O referencing. |
| 14 | VCC | Primary supply rail; powers all six inverters and defines output voltage levels. |
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. |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V input signals independent of VCC, enabling mixed-voltage signal translation. |
| Schmitt-trigger hysteresis | 0.4–1.5 V window ensures clean edge regeneration on slow-rising or noisy sensor signals. |
| Low static current | <2.0 μA ICC at VCC = 5.5 V and no switching - critical for always-on automotive subsystems. |
| Side-wettable flanks not applicable | SO14 package (SOT108-1) lacks side-wettable flanks; AOI requires top-surface solder inspection only. |
Applications
| Engine Control Unit (ECU) Sensor Interface | Body Control Module (BCM) Switch Debouncing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverting Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHC14D-Q100 | CMOS-input thresholds (VT+ ≈ 4.4 V at VCC = 4.5 V); higher noise immunity but incompatible with TTL sources. | Requires 3.3 V or 5 V CMOS-level inputs; unsuitable for legacy 5 V TTL sensor interfaces. | Select when interfacing with modern low-voltage microcontrollers or when maximum noise margin is prioritized over legacy compatibility. |
| SN74LV14AQPWRQ1 | Lower VCC range (2.0–5.5 V); typical tpd = 7.5 ns (CL = 50 pF); identical AEC-Q100 Grade 1 rating. | Better suited for mixed-supply systems (e.g., 3.3 V MCU + 5 V peripherals) due to wider input voltage tolerance. | Prefer when designing new platforms with dual-voltage domains or requiring lower static current (<1 μA typical). |
Compared with 74AHCT14D-Q100,118, the 74AHC14D-Q100 offers superior noise immunity but sacrifices TTL compatibility, while the SN74LV14AQPWRQ1 provides broader supply flexibility and lower quiescent current-making it preferable for next-generation low-power automotive electronics.

FAQ
Is 74AHCT14D-Q100,118 pin-compatible with standard 74HC14 or 74LS14?
Yes, it uses the industry-standard SO14 pinout (SOT108-1) matching 74HC14 and 74LS14. However, unlike 74LS14, it features Schmitt-trigger inputs and AEC-Q100 qualification; unlike 74HC14, it accepts TTL-level inputs and operates up to +125 °C.
Can 74AHCT14D-Q100,118 operate with a 3.3 V supply?
No. The 74AHCT14 variant is specified only for 4.5–5.5 V operation per its recommended conditions table. For 3.3 V systems, use the 74AHC14D-Q100 or 74LV14AQPWRQ1 variants instead.
What is the purpose of the hysteresis in this device?
Hysteresis (0.4–1.5 V) prevents multiple output transitions when input signals cross the threshold slowly or contain noise. This ensures single, clean edges for timing-critical functions like crankshaft position decoding or switch debouncing.
Does the SO14 package support automatic optical inspection (AOI)?
The SO14 (SOT108-1) package does not feature side-wettable flanks. AOI must rely on top-surface solder joint imaging only; for full AOI compatibility, consider the DHVQFN14 (SOT762-1) variant of this part.
