Product details
Overview
74HC1G14GW-Q100 from Nexperia is a single-channel CMOS inverting Schmitt trigger IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0–6.0 V, input hysteresis (VH) of 0.6–1.6 V, and propagation delay as low as 11 ns at VCC = 6.0 V/CL = 50 pF - used for noise-immune signal conditioning in engine control modules and body electronics.
For engineers reviewing the 74HC1G14GW-Q100 datasheet, 74HC1G14GW-Q100 pinout, 74HC1G14GW-Q100 application, or 74HC1G14GW-Q100 equivalent, key selection criteria include Schmitt-trigger hysteresis width, automotive temperature compliance (-40 °C to +125 °C), TSSOP5 package footprint, TTL/CMOS input compatibility, and dynamic power dissipation (CPD = 20 pF).
Technical Context
This device implements a single inverter with hysteresis-based input thresholding: VT+ ranges from 0.7 V (VCC = 2.0 V) to 5.9 V (VCC = 6.0 V); VT− ranges from 0.2 V to 4.2 V; resulting in VH = VT+ − VT− of 0.6–1.6 V. Input clamp diodes enable safe interfacing to voltages exceeding VCC when current-limiting resistors are used.
It delivers symmetrical output drive (±12.5 mA), balanced tPLH/tPHL propagation delays, and operates across two logic families: 74HC1G14GW-Q100 accepts CMOS-level inputs, while its HCT variant supports TTL-level inputs. Latch-up immunity exceeds 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - enables direct integration into 3.3 V and 5.0 V automotive subsystems without level-shifting. |
| Hysteresis Voltage (VH) | 0.6–1.6 V - ensures robust noise rejection on slow-rising signals such as sensor outputs or mechanical switch bounce. |
| Propagation Delay | 11 ns (VCC = 6.0 V, CL = 50 pF) - supports reliable timing in relaxation oscillators and pulse shaping up to ~30 MHz. |
| Output Drive | ±12.5 mA - sufficient to directly drive small capacitive loads or interface with subsequent CMOS/TTL stages. |
| Input Leakage Current | ≤1.0 μA at VCC = 6.0 V - minimizes standby current impact in always-on vehicle modules. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets stringent automotive board-level ESD requirements per JS-001/JS-002. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and transmission control applications. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package, 5-lead, 1.25 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - must remain unconnected; not usable as ground or dummy pad. |
| 2 | A | Inverting Schmitt-trigger input - accepts slow-rising/falling waveforms and converts them to clean digital edges. |
| 3 | GND | Ground reference (0 V) - required for stable biasing and noise immunity; must be low-impedance path. |
| 4 | Y | Inverted output - provides rail-to-rail CMOS-compatible logic swing with symmetrical rise/fall times. |
| 5 | VCC | Positive supply - powers internal circuitry; requires local 100 nF decoupling near pin for transient stability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| Schmitt-trigger input hysteresis | Configurable VT+ and VT− thresholds ensure jitter-free output even with noisy or slowly transitioning inputs. |
| Clamp diode protected inputs | Enables safe overvoltage tolerance (VI < -0.5 V or VI > VCC + 0.5 V) when series resistors limit current to ≤20 mA. |
| Low dynamic power dissipation | CPD = 20 pF allows predictable switching power calculation: PD = CPD × VCC² × fi + Σ(CL × VCC² × fo). |
| Unlimited input rise/fall times | No minimum edge rate requirement - supports direct interfacing with RC networks, thermistors, or mechanical switches. |
Applications
| Waveform Shaping | Pulse Conditioning |
|---|---|
|
Use Scenario: Converting noisy analog sensor outputs (e.g., crankshaft position Hall effect signals) into clean square waves for microcontroller capture. IC Role / Device Role / Timing Role: Inverting Schmitt trigger providing hysteresis-based noise filtering and edge sharpening before MCU timer input.

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverting Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT1G14GW-Q100 | TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5 V); otherwise identical pinout, package, and AEC-Q100 qualification. | Better suited for mixed-logic systems with legacy 5 V TTL sources; slightly higher input current during transition. | Select when interfacing with standard 5 V TTL outputs; avoid if driving from high-impedance CMOS sources below 3.3 V. |
| SN74LVC1G14QDRYRQ1 | TI's AEC-Q100 Grade 1 part; wider VCC range (1.65–5.5 V); lower CPD (12 pF); different pinout (pin 1 = GND, pin 2 = A, pin 3 = Y, pin 4 = VCC, pin 5 = n.c.). | Requires PCB layout revision due to swapped VCC/GND pins; optimized for 1.8 V/3.3 V domains rather than 5 V automotive rails. | Choose only for new designs targeting 1.8 V logic or where lower dynamic power is critical; not drop-in replaceable. |
Compared with 74HC1G14GW-Q100, the 74HCT1G14GW-Q100 offers TTL input compatibility at no layout cost, while SN74LVC1G14QDRYRQ1 trades pin compatibility for lower-voltage operation and reduced switching power - making the original the optimal choice for 5 V automotive signal conditioning with zero redesign effort.

FAQ
What is the maximum allowable input voltage relative to VCC?
The 74HC1G14GW-Q100 features integrated input clamp diodes that permit safe operation with input voltages up to VCC + 0.5 V or down to -0.5 V, provided external current-limiting resistors restrict IIK to ±20 mA. This enables direct interfacing with higher-voltage sensors or legacy 12 V signal lines when properly biased.
Can this device drive a 50 pF load at 6.0 V while maintaining specified propagation delay?
Yes - the datasheet guarantees tpd ≤ 26 ns (max) at VCC = 6.0 V and CL = 50 pF across -40 °C to +125 °C. Measured typical delay is 11 ns under those conditions, confirming full timing margin for high-speed waveform shaping in automotive timing-critical circuits.
Is pin 1 of the TSSOP5 package marked, and how is it oriented?
Yes - pin 1 is identified by a small dot or notch located on the lower-left corner of the device body, directly below the marking code "HF" laser-etched on the top surface. The pin numbering follows standard TSSOP convention: counterclockwise from pin 1, with pin 5 being VCC at the upper-right corner.
How does hysteresis improve performance in relaxation oscillator circuits?
Hysteresis defines distinct VT+ and VT− thresholds, enabling stable oscillation by ensuring the output toggles only after the capacitor voltage crosses both upper and lower bounds. For 74HC1G14GW-Q100, VH = 0.6–1.6 V ensures reliable startup and frequency stability across temperature and supply variations in R-C based oscillators used for LED flashers or diagnostic tone generation.
