Product details
Overview
74AHC14D-Q100 from Nexperia is an automotive-grade hex inverting Schmitt trigger IC with CMOS-level inputs, 2.0 V to 5.5 V supply range, -40 °C to +125 °C operating temperature, and overvoltage-tolerant inputs up to 5.5 V - used for noise-immune signal conditioning in engine control units and body electronics.
For engineers reviewing the 74AHC14D-Q100 datasheet, 74AHC14D-Q100 pinout, 74AHC14D-Q100 application, or 74AHC14D-Q100 equivalent, this page delivers verified functional role, Schmitt-trigger hysteresis values, propagation delay specs at 3.0 V/4.5 V, input/output voltage thresholds, and SO14 package terminal mapping - all confirmed against Nexperia's Rev. 4 (10 April 2024) product data sheet.
Technical Context
This device implements six independent inverting Schmitt-trigger buffers with hysteresis defined by VT+ (e.g., 3.15 V at VCC = 4.5 V) and VT- (e.g., 1.35 V at VCC = 4.5 V), yielding 1.8 V typical hysteresis for robust noise rejection in automotive sensor interfaces.
It operates across dual voltage domains: inputs tolerate up to 5.5 V regardless of VCC, enabling level translation between 3.3 V logic and 5 V subsystems; output drive capability is ±8 mA at VCC = 4.5 V with VOL ≤ 0.36 V and VOH ≥ 3.94 V under load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Hex inverting Schmitt trigger - provides noise-immune digital inversion with hysteresis to prevent chatter on slow or noisy signals. |
| Supply Voltage Range | 2.0 V to 5.5 V - supports direct integration into 3.3 V and 5 V automotive subsystems without external level shifters. |
| Hysteresis Voltage (VH) | 1.8 V typical at VCC = 4.5 V - ensures ≥1.4 V minimum hysteresis for reliable switching in high-EMI environments like powertrain modules. |
| Propagation Delay (tpd) | 3.2 ns typ / 11.0 ns max at VCC = 4.5 V, CL = 15 pF - enables timing-critical edge detection in motor position feedback circuits. |
| Input Overvoltage Tolerance | 5.5 V absolute max - allows safe interfacing with 5 V sensors while powered from 3.3 V rails, eliminating clamping diodes. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for under-hood automotive applications including transmission control and ADAS sensor preprocessing. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets stringent automotive assembly ESD requirements without additional protection circuitry. |
Pinout & Package
74AHC14D-Q100 uses the SO14 (SOT108-1) plastic small outline package: 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) | Schmitt-trigger input pins - accept noisy analog-like signals and convert to clean digital outputs with hysteresis. |
| 2, 4, 6, 8, 10, 12 | Data Output (1Y–6Y) | Inverted buffered outputs - drive downstream logic or small capacitive loads (≤50 pF) with controlled rise/fall times. |
| 7 | GND | Ground reference (0 V) - must be low-impedance connection to minimize ground bounce in multi-channel switching. |
| 14 | VCC | Positive supply rail - decoupling capacitor (100 nF ceramic) required within 5 mm for stable operation at full speed. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 certified - validated for continuous operation from −40 °C to +125 °C in engine bay and chassis modules. |
| Overvoltage-tolerant inputs | VI up to 5.5 V independent of VCC - enables mixed-voltage signal routing without external translators or resistive dividers. |
| High noise immunity | 1.8 V typical hysteresis at 4.5 V supply - rejects common-mode noise spikes up to ±900 mV on sensor lines. |
| CMOS low power dissipation | ICC ≤ 40 μA max at VCC = 5.5 V, TA = +125 °C - reduces thermal load in densely packed ECUs with multiple channels active. |
| Balanced propagation delays | tpd variation ≤ 1.0 ns across all six channels - ensures deterministic timing alignment in multi-sensor synchronization applications. |
Applications
| Engine Control Unit (ECU) Sensor Interface | Body Control Module (BCM) Switch Debouncing |
|---|---|
|
Use Scenario: Conditioning crankshaft position sensor signals before feeding to microcontroller capture timers. IC Role / Device Role / Timing Role: Schmitt-trigger inverter converts analog sine-wave or variable-reluctance output into clean square wave with jitter suppression.

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 |
|---|---|---|---|
| 74AHCT14D-Q100 | TTL-compatible inputs (VIH = 2.0 V min), identical SO14 package and AEC-Q100 Grade 1 rating. | Designed for legacy 5 V TTL systems; lacks 2.0 V–3.3 V compatibility of AHC variant. | Select when interfacing with older 5 V microcontrollers or logic families requiring TTL input thresholds. |
| SN74LV14AQPWRQ1 | TI part with LV logic family: lower VCC range (1.65 V–5.5 V), higher ICC (100 μA max), same Grade 1 qualification. | Optimized for ultra-low-voltage domains (e.g., 1.8 V MCUs); exhibits higher static current at 125 °C. | Prefer when system-wide voltage scaling below 2.0 V is required, accepting trade-off in quiescent power. |
Compared with 74AHCT14D-Q100, the AHC version offers broader supply flexibility (2.0 V min) and superior noise margin at low VCC; versus SN74LV14AQPWRQ1, it delivers 2.5× lower ICC at +125 °C but lacks sub-2.0 V operation - critical for modern low-power domain partitioning in next-gen ECUs.

FAQ
Is 74AHC14D-Q100 pin-compatible with standard 74HC14 or 74LS14?
No - while functionally similar, 74AHC14D-Q100 uses SO14 (SOT108-1) packaging with specific pinout (e.g., GND at pin 7, VCC at pin 14), whereas 74LS14 uses different logic families and may have incompatible input thresholds and drive strength. Direct substitution requires verification of VIH/VIL, fan-out, and timing margins per application.
Can 74AHC14D-Q100 operate reliably at 2.0 V supply in automotive environments?
Yes - the device is fully specified down to 2.0 V across −40 °C to +125 °C, with guaranteed VIH = 1.9 V and VIL = 0.1 V at that voltage. Propagation delay increases to 12.8 ns max (CL = 15 pF), but remains functional for non-timing-critical debouncing and level translation tasks in low-power domains.
What is the maximum capacitive load this device can drive without signal degradation?
74AHC14D-Q100 is characterized up to 50 pF load capacitance, with tpd = 11.0 ns max at VCC = 4.5 V. Driving >50 pF risks exceeding recommended output transition times and may cause excessive ICC due to increased dynamic loading - external buffering is advised for >100 pF traces or multi-load fan-out.
Does the SO14 package support automated optical inspection (AOI) of solder joints?
No - only the DHVQFN14 (SOT762-1) variant features Side-Wettable Flanks explicitly designed for AOI. The SO14 (SOT108-1) package relies on X-ray or electrical test for post-reflow joint validation; its gull-wing leads require precise stencil design and reflow profiling to ensure coplanarity and void-free solder fillets.
