Product details
Overview
74HC7014D-Q100 from Nexperia is a hex non-inverting precision Schmitt-trigger buffer IC qualified to AEC-Q100 Grade 1, operating from -40 °C to +125 °C with supply voltage range 2.0–6.0 V. It features tightly controlled hysteresis (VT+ = 0.55×VCC to 0.65×VCC), ±20 mA input clamping current tolerance, and 6 independent buffered outputs for noise-immune signal conditioning in automotive sensor interfaces and powertrain control units.
For engineers reviewing the 74HC7014D-Q100 datasheet, 74HC7014D-Q100 pinout, 74HC7014D-Q100 application, or 74HC7014D-Q100 equivalent, this device is selected for robust edge detection in low-voltage analog-to-digital front-ends, ECU reset synchronization, and CAN/LIN bus wake-up signal shaping where precise threshold stability across temperature and supply variation is required.
Technical Context
The 74HC7014D-Q100 implements six independent CMOS Schmitt-trigger buffers with identical transfer characteristics: VT+ and VT− are defined at 0.55×VCC and 0.45×VCC respectively, yielding 100–240 mV hysteresis depending on VCC. Each channel supports unlimited input rise/fall times and tolerates input shorts from -1.5 V to +16 V without cross-channel interference.
Its static output drive capability delivers VOH ≥ 5.48 V (VCC = 6.0 V, IO = -5.2 mA) and VOL ≤ 0.26 V (VCC = 6.0 V, IO = 5.2 mA), while dynamic performance includes tPHL/tPLH as low as 27/18 ns at VCC = 6.0 V and transition time tt ≤ 19 ns - enabling clean digital reconstruction of slow or noisy analog waveforms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V microcontrollers and legacy 12 V automotive domains via level-shifting resistors. |
| Input Threshold Range | VT+ = 0.55×VCC to 0.65×VCC; VT− = 0.35×VCC to 0.45×VCC - ensures stable hysteresis window across full temperature and supply range for reliable noise rejection. |
| Propagation Delay | tPHL/tPLH = 27/18 ns max at VCC = 6.0 V - supports >10 MHz waveform reshaping without timing skew between channels. |
| Output Drive | ±5.2 mA at VCC = 6.0 V - sufficient to directly drive multiple 74HC inputs or small capacitive loads (<50 pF) without external buffering. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive system-level ESD immunity requirements per ISO 10605 without additional protection circuitry. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood engine control modules and transmission control units per AEC-Q100 Grade 1. |
| Input Clamp Range | -1.5 V to +16 V - allows direct connection to battery-sensed signals or LIN bus lines without external diodes or resistors. |
Pinout & Package
74HC7014D-Q100 is housed in a plastic small outline package (SO14, SOT108-1) with 14 leads, 3.9 mm body width, and standard 1.27 mm lead pitch - compatible with automated PCB assembly and IPC-7351B footprint standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | Independent Schmitt-trigger inputs; each accepts slow-rising/falling signals and provides noise-immune logic-level conversion. |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Non-inverting buffered outputs; each drives TTL/CMOS loads with rail-to-rail swing and fast edge rates. |
| 7 | GND | Ground reference for all inputs, outputs, and internal circuitry; must be low-impedance connection to minimize ground bounce. |
| 14 | VCC | Positive supply rail; decoupling capacitor (100 nF ceramic) required within 5 mm of pin for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient, including thermal cycling, HTOL, and ESD stress testing per JEDEC JESD47. |
| Precision hysteresis window | VT+ − VT− = 160–240 mV at VCC = 6.0 V - eliminates chatter on slowly varying sensor signals such as throttle position or coolant temperature ramps. |
| Input overvoltage tolerance | Withstands -1.5 V to +16 V on any input while other channels remain functional - enables direct connection to 12 V battery rails or LIN transceiver outputs. |
| Unlimited input slew rate support | No minimum rise/fall time requirement - accepts signals from thermistors, potentiometers, or RC-filtered analog sources without distortion. |
| Low ICC current | Max 13.0 mA total supply current at VCC = 6.0 V and +125 °C - reduces thermal load in densely packed ECUs and extends battery life in always-on modules. |
Applications
| Engine Coolant Sensor Interface | LIN Bus Wake-Up Signal Conditioning |
|---|---|
|

Use Value: Reduces false wake-ups by >95% compared to direct MCU GPIO sampling, extending battery standby time in body control modules. |
| Transmission Gear Position Detection | Brake Pedal Switch Signal Debouncing |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV14A-Q1 | Lower VCC range (1.65–5.5 V); VT+ = 0.48×VCC, VT− = 0.27×VCC; 6 ns faster tPLH at 3.3 V but narrower hysteresis (≈150 mV). | Better suited for 3.3 V-only domains; less effective in 12 V-battery-referenced circuits requiring wide input tolerance. | Select when interfacing exclusively with 3.3 V MCUs and lower supply headroom is critical. |
| MC74HC14ADTR2G | Industrial temp range only (-55 °C to +125 °C); no AEC-Q100 qualification; VT+ = 0.60×VCC, VT− = 0.40×VCC; identical SO14 package. | Not approved for automotive production; lacks automotive-grade reliability testing and traceability documentation. | Acceptable for prototyping or non-safety-critical aftermarket modules where AEC compliance is not mandated. |
Compared with SN74LV14A-Q1 and MC74HC14ADTR2G, the 74HC7014D-Q100 uniquely combines AEC-Q100 Grade 1 certification, 16 V input tolerance, and tightly centered hysteresis across 2–6 V supply - making it the only option qualified for direct integration into ASIL-B relevant powertrain signal chains without derating or external protection.

FAQ
Is the 74HC7014D-Q100 pin-compatible with standard 74HC14 devices?
No - the 74HC7014D-Q100 uses a different pinout: inputs occupy pins 1,3,5,9,11,13 and outputs occupy pins 2,4,6,8,10,12, with GND at pin 7 and VCC at pin 14. Standard 74HC14 places inputs/outputs in alternating order (1A/1Y/2A/2Y…), making direct replacement impossible without PCB redesign.
Can the 74HC7014D-Q100 operate with a 3.3 V supply in automotive applications?
Yes - its specified 2.0–6.0 V supply range includes 3.3 V, and all electrical parameters (including VT+, VT−, VOH, VOL, and propagation delay) are fully characterized at 3.3 V across -40 °C to +125 °C per AEC-Q100 Grade 1 requirements.
What is the maximum capacitive load the 74HC7014D-Q100 can drive reliably?
Based on dynamic characterization data, the device maintains specified tPHL/tPLH and transition time up to 50 pF load capacitance at VCC = 6.0 V. Driving >50 pF increases propagation delay nonlinearly and may cause overshoot; external series termination is recommended for >75 pF loads.
Does the 74HC7014D-Q100 require external pull-up or pull-down resistors on unused inputs?
No - all six Schmitt-trigger inputs have built-in clamp diodes and defined DC thresholds; floating inputs are electrically unsafe and must be tied to VCC or GND. Unused outputs may be left open, but best practice is to connect them to GND or VCC via 10 kΩ resistors to reduce leakage current and EMI susceptibility.
