Nexperia USA Inc. 74AHCT04D-Q100J

Overview

74AHCT04D-Q100 from Nexperia is an automotive-qualified hex inverter IC with TTL-compatible inputs, 14-pin SO14 package, -40 °C to +125 °C operating range, propagation delay ≤7.0 ns (VCC = 5.0 V, CL = 15 pF), and AEC-Q100 Grade 1 qualification - used for signal inversion and level translation in engine control units and body electronics.

For engineers reviewing the 74AHCT04D-Q100 datasheet, 74AHCT04D-Q100 pinout, 74AHCT04D-Q100 application, or 74AHCT04D-Q100 equivalent, this page delivers verified functional role, automotive-grade timing specs, input/output voltage thresholds, ESD ratings, and package-specific thermal derating data - all confirmed against Nexperia's Rev. 4 (Feb 2024) product data sheet.

Technical Context

This device implements six independent CMOS inverter stages with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interface with legacy 5 V logic systems. Its balanced propagation delays (tPLH ≈ tPHL) ensure minimal duty-cycle distortion in clock buffering or waveform shaping.

It operates across two supply ranges: 4.5–5.5 V nominal, with output drive capability of ±8.0 mA at VOH ≥ 3.70 V and VOL ≤ 0.55 V (VCC = 4.5 V, -40 °C to +125 °C), and features input clamping diodes supporting VI up to 7.0 V - critical for noise-immune automotive bus interfacing.

Key Specifications

Pinout & Package

74AHCT04D-Q100 uses the SO14 (SOT108-1) plastic small outline package: 14-lead, 3.9 mm body width, 1.27 mm lead pitch, and gull-wing leads compatible with standard reflow and AOI inspection.

FAQ

Is 74AHCT04D-Q100 pin-compatible with standard 74LS04?

Yes - it is pin-compatible with Low-power Schottky TTL (LSTTL) devices like 74LS04 and offers identical SO14 pinout (1A–6A inputs on odd pins, 1Y–6Y outputs on even pins, GND on pin 7, VCC on pin 14). Input thresholds match TTL levels, and output drive strength exceeds LS-series, enabling direct drop-in replacement without layout changes.

What is the maximum allowable input voltage when VCC = 0 V?

The absolute maximum input voltage is -0.5 V to +7.0 V regardless of VCC state. When VCC = 0 V, inputs remain protected by internal clamping diodes rated for ±20 mA clamp current, allowing safe hot-plug or partial-power-down operation in modular automotive subsystems.

Does this device support mixed-voltage interfacing (e.g., 3.3 V MCU to 5 V peripheral)?

No - the 74AHCT04D-Q100 is strictly a 5 V-only device with TTL input thresholds optimized for 4.5–5.5 V VCC. For 3.3 V-to-5 V translation, use the 74AHC04D-Q100 variant (CMOS inputs) or dedicated level translators like NX3P2266; applying 3.3 V inputs risks marginal VIH recognition below 2.0 V.

How does the SO14 package's thermal derating affect design at 125 °C ambient?

For SO14 (SOT108-1), total power dissipation derates linearly at 10.1 mW/K above 100 °C. At 125 °C ambient, Ptot drops to 500 mW − (25 K × 10.1 mW/K) = 247.5 mW - limiting maximum toggle frequency to ~20 MHz with full 6-channel activity and 50 pF load, requiring careful thermal layout or reduced channel utilization.
