Product details
Overview
74HC14PW-Q100 from Nexperia is an automotive-qualified hex inverting Schmitt trigger IC with TTL-compatible input thresholds, 2.0–6.0 V supply range, -40 °C to +125 °C operating temperature, and TSSOP14 (SOT402-1) package. It converts slow-rising/falling analog or noisy digital inputs into clean, jitter-free square-wave outputs for signal conditioning in engine control units and body electronics.
For engineers reviewing the 74HC14PW-Q100 datasheet, 74HC14PW-Q100 pinout, 74HC14PW-Q100 application, or 74HC14PW-Q100 equivalent, this device is selected for robust noise immunity, guaranteed hysteresis (0.6–1.6 V), sub-25 ns propagation delay at 6 V, and AEC-Q100 Grade 1 qualification in automotive timing and waveform shaping circuits.
Technical Context
The 74HC14PW-Q100 implements six independent CMOS inverting Schmitt triggers, each with asymmetric input threshold voltages (VT+ = 2.1–4.2 V, VT− = 1.2–2.6 V at VCC = 6 V) yielding 0.6–1.6 V hysteresis. Its input clamp diodes support interfacing to voltages exceeding VCC when used with current-limiting resistors.
It operates across 2.0–6.0 V with static ICC ≤ 40 μA at 125 °C and dynamic CPD = 7 pF, enabling low-power operation in battery-sensitive systems. Input rise/fall times are unrestricted, and output drive capability is ±25 mA with VOL ≤ 0.4 V at 4.0 mA sink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V logic domains without level shifters |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 1 |
| Propagation Delay | 12–32 ns at VCC = 6.0 V, CL = 50 pF - enables reliable timing in sub-30 MHz relaxation oscillators and pulse edge detection |
| Hysteresis Voltage (VH) | 0.6–1.6 V (VCC = 2.0–6.0 V) - rejects noise up to ±0.8 V on input signals without false triggering |
| Input Thresholds (VT+, VT−) | VT+ = 2.1–4.2 V, VT− = 1.2–2.6 V at VCC = 6 V - ensures clean switching even with slow 10–100 µs ramp inputs |
| Output Drive Strength | ±25 mA - sufficient to directly drive LEDs, small relays, or fan-out to ≥10 standard CMOS loads |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - withstands handling and board-level ESD events in production and field service |
Pinout & Package
TSSOP14 (SOT402-1) package: 14-lead thin shrink small outline, 4.4 mm body width, 0.65 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data Input (1A–6A) | Schmitt-triggered inverter inputs - accept slow/noisy signals; clamp diodes allow overvoltage tolerance with series resistors |
| 2, 4, 6, 8, 10, 12 | Data Output (1Y–6Y) | Inverted, rail-to-rail CMOS outputs - drive downstream logic or passive loads with defined VOH/VOL |
| 7 | GND | Ground reference (0 V) - must be low-impedance connection to minimize ground bounce in multi-channel switching |
| 14 | VCC | Positive supply - decoupling capacitor (100 nF) required within 5 mm for stable high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C with full reliability testing per stress test conditions |
| Unlimited input rise/fall times | Accepts arbitrarily slow transitions (ms-scale) without metastability or oscillation due to Schmitt architecture |
| Wide VCC range (2.0–6.0 V) | Eliminates need for separate voltage regulators when interfacing mixed-supply subsystems (e.g., 3.3 V sensors + 5 V MCU) |
| High noise immunity | Minimum 0.6 V hysteresis ensures rejection of common-mode noise and EMI-induced glitches on PCB traces |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints on bottom terminals - critical for automotive manufacturing traceability |
Applications
| Engine Control Unit (ECU) Signal Conditioning | Body Control Module (BCM) Switch Debouncing |
|---|---|
Use Scenario: Converting noisy crankshaft position sensor analog pulses into clean digital timing edges for microcontroller capture. IC Role / Device Role / Timing Role: Hex Schmitt inverter acts as a noise-immune waveform shaper, transforming slow-rising magnetic pickup signals into precise 50% duty-cycle square waves. Use Value: Eliminates software debouncing overhead and prevents missed ignition events caused by EMI-induced false zero-crossings. | Use Scenario: Cleaning mechanical switch bounce from door lock/unlock buttons before feeding to BCM microcontroller GPIO. IC Role / Device Role / Timing Role: Inverting Schmitt trigger provides hardware-level hysteresis filtering, converting 5–20 ms contact chatter into single, glitch-free logic transitions. Use Value: Reduces firmware interrupt load and eliminates spurious lock/unlock commands without requiring RC filters or additional MCU pins. |
| Automotive Dashboard LED Driver Interface | Infotainment System Reset Pulse Generation |
Use Scenario: Driving discrete indicator LEDs from low-current MCU outputs via open-drain or push-pull configurations. IC Role / Device Role / Timing Role: Inverter buffer stage provides current gain and logic inversion to match LED anode/cathode drive topology. Use Value: Enables direct LED control using standard 3.3 V/5 V MCU I/O while maintaining <100 ns edge integrity for synchronized illumination sequences. | Use Scenario: Generating clean, fixed-duration reset pulses for infotainment SoCs during power-up sequencing. IC Role / Device Role / Timing Role: One gate configured as astable multivibrator with RC network produces precise 100–500 ms reset assertion window. Use Value: Guarantees reliable SoC initialization without dependency on external timing ICs or complex power management IC features. |
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 |
|---|---|---|---|
| 74HCT14PW-Q100 | TTL-compatible input thresholds (VT+ ≈ 1.4 V, VT− ≈ 0.9 V at VCC = 4.5 V); identical pinout and package | Better interoperability with legacy 5 V TTL logic; slightly lower hysteresis (0.4–0.6 V) reduces noise margin vs. HC variant | Select when interfacing predominantly with 5 V TTL sources; avoid in mixed-voltage systems where HC's wider VCC range is needed |
| SN74LV14APWRE4 | Lower VCC range (2.0–5.5 V); higher drive strength (±12 mA typical); non-automotive grade (industrial only) | Lacks AEC-Q100 qualification; unsuitable for safety-critical or under-hood deployment | Acceptable for non-automotive embedded systems requiring LV logic compatibility; not recommended for automotive BOMs |
Compared with 74HCT14PW-Q100 and SN74LV14APWRE4, the 74HC14PW-Q100 delivers superior noise immunity across its full 2–6 V supply range and meets mandatory automotive qualification-making it the only choice for ECU, BCM, and ADAS subsystems requiring long-term reliability under thermal stress.

FAQ
What is the maximum clock frequency supported by the 74HC14PW-Q100?
The 74HC14PW-Q100 is not a clocked device-it has no internal clock and operates asynchronously. Its usable signal frequency depends on propagation delay and load capacitance. With CL = 50 pF and VCC = 6 V, tpd ≤ 32 ns supports clean edge generation up to ~15 MHz for repetitive square-wave output, but it is primarily used for waveform shaping, not clock distribution.
Can the 74HC14PW-Q100 drive a 10 kΩ pull-up resistor directly?
Yes. With VOH ≥ 5.2 V at VCC = 6.0 V and IO = −5.2 mA, the output can source sufficient current to maintain valid HIGH levels into 10 kΩ (I = 0.6 mA at 6 V), well within its ±25 mA rating. No external buffer is needed for standard logic interfacing.
Is the exposed pad on the TSSOP14 package electrically connected?
No. The exposed pad in the SOT402-1 (TSSOP14) package is a thermal enhancement feature only and has no electrical connection. Per Nexperia documentation, it may remain floating or be connected to GND for improved thermal performance-but it must never be tied to VCC or any other voltage.
How does the 74HC14PW-Q100 differ from standard 74HC14 in non-automotive versions?
The 74HC14PW-Q100 undergoes full AEC-Q100 Grade 1 stress testing (temperature cycling, HTOL, ESD), uses automotive-grade wafer lots and assembly processes, and is supplied with PPAP documentation. Electrically, it matches the industrial 74HC14PW but guarantees operation from −40 °C to +125 °C with tighter parametric limits and lot traceability.
