Product details
Overview
74HCT3G14DP-Q100 from Nexperia is a triple inverting Schmitt trigger IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with 4.5 V to 5.5 V supply, TTL-compatible inputs, and 4.18 V min VOH at 4.5 V/–4.0 mA. It delivers sharp signal conditioning in noisy engine control and body electronics interfaces.
For engineers reviewing the 74HCT3G14DP-Q100 datasheet, 74HCT3G14DP-Q100 pinout, 74HCT3G14DP-Q100 application, or 74HCT3G14DP-Q100 equivalent, this page provides verified pin functions, hysteresis thresholds (VT+ = 1.20–1.90 V, VT− = 0.50–1.20 V), propagation delay (21–48 ns), automotive temperature range compliance, and direct substitution guidance against industry-standard alternatives.
Technical Context
This device implements three independent Schmitt-trigger inverters with input clamp diodes enabling safe interfacing to voltages exceeding VCC via current-limiting resistors. Its transfer characteristic exhibits defined hysteresis (VH = 0.40–0.71 V) to reject noise on slow-rising signals.
The logic function is strictly inverting (L→H, H→L), with static input thresholds referenced to VCC and dynamic timing specified under controlled load conditions (50 pF, 1 kΩ). Input leakage remains ≤±1.0 μA across full temperature range, supporting low-power system monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with 5 V automotive microcontroller I/O rails and stable operation across battery voltage transients. |
| Input Thresholds (VT+, VT−) | 1.20–1.90 V / 0.50–1.20 V - Provides ≥0.4 V hysteresis to suppress false triggering from EMI in under-hood environments. |
| Propagation Delay | 21–48 ns - Enables reliable timing in relaxation oscillators and pulse shaping up to ~10 MHz edge rates. |
| Output Drive | ±4.0 mA - Sufficient to directly drive small capacitive loads (e.g., 50 pF traces) without external buffering in sensor interface circuits. |
| Operating Temperature | –40 °C to +125 °C - Meets AEC-Q100 Grade 1 requirements for under-hood and powertrain applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Protects against assembly- and field-level electrostatic discharge in manufacturing and service environments. |
| Power Dissipation | 250 mW max (TSSOP8) - Supports continuous operation in compact automotive modules with limited thermal mass. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.5 mm lead length, pin 1 indicator below marking code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 | 1A, 2A, 3A | Independent Schmitt-trigger inputs - Accept slow/noisy signals; clamp diodes allow overvoltage tolerance with series resistors. |
| 2, 5, 7 | 3Y, 1Y, 2Y | Inverted outputs - Each drives one logic path; output swing spans full rail (0 V to VCC) with defined VOL/VOH. |
| 4 | GND | Ground reference - Must be low-impedance connection to minimize ground bounce in multi-inverter switching. |
| 8 | VCC | Supply rail - Decoupling capacitor (100 nF) required within 5 mm for stable noise immunity and timing performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use with full temperature and reliability testing per JEDEC JESD47 and AEC standards. |
| TTL-level input compatibility | Accepts standard 5 V TTL logic thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), enabling direct interface with legacy controllers. |
| Unlimited input rise/fall times | Eliminates need for external RC filtering; supports arbitrarily slow analog-like transitions without metastability. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events. |
| Low ICC standby current | ≤1.0 μA typical per input at 25 °C - minimizes quiescent power in always-on vehicle subsystems. |
Applications
| Engine Control Unit Signal Conditioning | Body Control Module Switch Debouncing |
|---|---|
Use Scenario: Cleaning crankshaft position sensor signals corrupted by ignition noise and alternator ripple. IC Role / Device Role / Timing Role: Triple Schmitt trigger converts noisy analog edges into clean digital pulses for microcontroller capture timers. Use Value: 0.4–0.71 V hysteresis rejects sub-microsecond spikes while preserving true edge timing for precise RPM calculation. | Use Scenario: Debouncing mechanical door lock/unlock switch inputs exposed to vibration and ESD. IC Role / Device Role / Timing Role: Inverting Schmitt trigger filters contact bounce and provides deterministic logic-level output to BCM MCU. Use Value: Guaranteed noise margin >400 mV ensures no false triggers even during 100 V/m radiated immunity testing. |
| Automotive Lighting PWM Shaping | Infotainment System Reset Sequencing |
Use Scenario: Converting slow-rising microcontroller reset signals into fast, jitter-free enable pulses for LED driver ICs. IC Role / Device Role / Timing Role: Single gate used as waveform shaper to eliminate slow-edge-induced timing uncertainty in lighting control paths. Use Value: 21–48 ns propagation delay ensures predictable turn-on timing across –40 °C to +125 °C ambient. | Use Scenario: Generating synchronized power-on reset pulses for multiple infotainment SoCs after main supply stabilization. IC Role / Device Role / Timing Role: One inverter stage buffers and sharpens delayed reset signals; remaining gates provide redundancy or auxiliary timing. Use Value: CMOS-level output swing (0 V to VCC) guarantees compatible logic thresholds for 3.3 V and 5 V SoC reset inputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV3G14DCUR | Lower VCC range (1.65–5.5 V); LV logic family; 3.3 V optimized; no AEC-Q100 qualification. | Suitable for non-automotive 3.3 V systems only; lacks high-temp validation and automotive reliability screening. | Select when cost-sensitive consumer designs require wider low-voltage operation but do not demand automotive qualification. |
| MC74VHC3G14DTT1G | VHC family; CMOS inputs; 2–5.5 V supply; AEC-Q100 Grade 2 (–40 °C to +105 °C); higher propagation delay (30–60 ns). | Valid for cabin electronics (Grade 2), not under-hood; slower timing limits high-frequency oscillator use. | Choose for cost-optimized cabin modules where 105 °C suffices and TTL input compatibility is unnecessary. |
Compared with SN74LV3G14DCUR and MC74VHC3G14DTT1G, the 74HCT3G14DP-Q100 uniquely combines TTL input compatibility, AEC-Q100 Grade 1 qualification, and sub-50 ns timing-making it the only option for robust 5 V automotive signal conditioning requiring guaranteed operation at +125 °C.

FAQ
What is the maximum recommended supply voltage for continuous operation?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 4.5 V to 5.5 V. Operation above 5.5 V risks exceeding static and dynamic specifications, particularly VOH/VOL margins and propagation delay consistency. Derating begins at 5.5 V per JEDEC JESD8C compliance requirements.
Can this device interface directly with 3.3 V microcontrollers?
No - the 74HCT3G14DP-Q100 has TTL-compatible inputs requiring VIH ≥ 2.0 V, but its output VOH is specified only down to 4.18 V at 4.5 V supply, making it incompatible with 3.3 V logic thresholds. For 3.3 V systems, use 74LVC3G14 or 74LV3G14 variants instead.
How does the input clamping diode affect PCB layout?
The integrated input clamp diodes allow safe connection of inputs to voltages exceeding VCC when used with series current-limiting resistors (e.g., 10 kΩ for 12 V bias). Layout must ensure resistor placement adjacent to the IC pin and avoid routing high-impedance nodes near noisy traces to prevent unintended conduction.
Is the TSSOP8 package RoHS and REACH compliant?
Yes - the SOT505-2 (TSSOP8) package used for 74HCT3G14DP-Q100 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound, as confirmed in Nexperia's official material declarations dated December 2023.
