Product details
Overview
74AHCT04BQ-Q100 from Nexperia is an automotive-qualified hex inverter IC with TTL-compatible inputs, 14-terminal DHVQFN package, -40 °C to +125 °C operating range, and 3.0–7.0 ns propagation delay at 5 V/50 pF load-used for signal inversion and level translation in engine control units and ADAS domain controllers.
For engineers reviewing the 74AHCT04BQ-Q100 datasheet, 74AHCT04BQ-Q100 pinout, 74AHCT04BQ-Q100 application, or 74AHCT04BQ-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, TTL-level input compatibility, balanced propagation delays, side-wettable flank package for AOI, and 8 mA output drive capability.
Technical Context
This device implements six independent CMOS inverter gates with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy LSTTL logic. It operates across full automotive temperature range (-40 °C to +125 °C) and supports supply voltages from 4.5 V to 5.5 V.
The DHVQFN14 package (SOT762-1) features side-wettable flanks for automated optical inspection of solder joints and thermal enhancement via exposed die pad. Input clamping current is ±20 mA, and output drive capability is ±8 mA at VOH/VOL specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Six independent inverters; each performs Boolean NOT operation on digital input signals. |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures stable operation in 5 V automotive power domains with ±10% tolerance. |
| Propagation Delay | 3.0–7.0 ns at VCC = 5.0 V, CL = 50 pF - enables high-speed signal conditioning in timing-critical control paths. |
| Output Drive | ±8 mA at VOH ≥ 3.70 V / VOL ≤ 0.55 V - sufficient to drive multiple LSTTL inputs or moderate capacitive loads. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - matches standard TTL logic levels for seamless interoperability with legacy systems. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for under-hood and safety-critical automotive applications. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets stringent automotive ESD immunity requirements per JS-001/JS-002. |
Pinout & Package
DHVQFN14 package (SOT762-1): 2.5 mm × 3.0 mm × 0.85 mm body, no leads, 14 terminals, side-wettable flanks, exposed thermal pad (non-electrical, optional GND connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data input (1A–6A) | Independent TTL-level logic inputs; accept 0–5.5 V, compatible with LSTTL outputs. |
| 2, 4, 6, 8, 10, 12 | Data output (1Y–6Y) | Inverted logic outputs; drive up to ±8 mA while maintaining VOH/VOL specs across temperature. |
| 7 | GND | Ground reference (0 V); mandatory connection for functional and EMI performance. |
| 14 | VCC | Positive supply rail (4.5–5.5 V); powers all six inverters and internal bias circuitry. |
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. |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply - eliminates need for level shifters when interfacing with legacy TTL systems. |
| Balanced propagation delays | tPLH and tPHL match within 0.5 ns typical - ensures precise timing symmetry in clock or enable signal inversion. |
| Side-wettable flanks (SWF) | Enables 100% automated optical inspection (AOI) of solder joints on bottom terminations - improves manufacturing yield and field reliability. |
| Low dynamic power dissipation | CPD = 13.9 pF - reduces switching power consumption in high-frequency control logic without compromising speed. |
Applications
| Engine Control Unit (ECU) | Advanced Driver Assistance Systems (ADAS) |
|---|---|
|

IC Role / Device Role / Timing Role: High-reliability logic inverter driving discrete MOSFET gate drivers in 12 V load switching circuits. Use Value: ±8 mA output drive sustains clean logic transitions into capacitive gate loads, preventing shoot-through in half-bridge drivers. |
Use Scenario: Signal conditioning of reset and interrupt lines between microcontroller and peripheral ICs in multimedia head units. IC Role / Device Role / Timing Role: Glitch-free inverter for debounced reset propagation and interrupt polarity correction in multi-core SoC environments. Use Value: Balanced tPLH/tPHL and low input capacitance (CI = 10 pF max) minimize timing skew and crosstalk in dense routing zones. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT04PW-Q100 | TSSOP14 package (SOT402-1); same electrical specs but larger footprint and no side-wettable flanks. | Suitable for manual rework or prototyping where AOI is not required; lower thermal performance than DHVQFN. | Select when board assembly lacks AOI capability or requires easier hand-soldering access. |
| SN74AHCT04QPWRQ1 | Texas Instruments part; identical function and AEC-Q100 Grade 1 rating, but different pinout (SOIC-14) and higher ICC (max 40 μA vs. 20 μA typical). | Compatible in legacy SOIC layouts; slightly higher static current may impact ultra-low-power sleep modes. | Choose for drop-in replacement in existing SOIC-14 designs where footprint compatibility is mandatory. |
Compared with 74AHCT04BQ-Q100, the PW variant trades AOI support and thermal efficiency for assembly flexibility, while the TI SN74AHCT04QPWRQ1 offers footprint compatibility at the cost of marginally higher quiescent current and no side-wettable flanks.

FAQ
Is 74AHCT04BQ-Q100 pin-compatible with standard 74LS04?
Yes - it is pin-compatible with Low-power Schottky TTL (LSTTL) devices like 74LS04 and maintains identical SO14, TSSOP14, and DHVQFN14 footprints across the 74AHCT04-Q100 family. Input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and output drive (±8 mA) align with LSTTL specifications, enabling direct replacement without layout changes.
What is the function of the exposed thermal pad on the DHVQFN package?
Terminal 1 index area and the exposed thermal pad (center underside) are mechanically and electrically isolated - no electrical requirement exists to connect it. If soldered, the pad must remain floating or be tied to GND; improper connection risks shorting or thermal stress. Its primary role is mechanical stability and enhanced heat conduction away from the die.
Can 74AHCT04BQ-Q100 operate at 3.3 V supply?
No - this is the AHCT variant, specified only for 4.5–5.5 V operation per Table 5. For 3.3 V systems, use the pin-compatible 74AHC04BQ-Q100 (CMOS-input version), which supports 2.0–5.5 V and has VIH = 1.5 V min at VCC = 2.0 V. Mixing variants risks incorrect logic interpretation or failure to switch.
How does the DHVQFN14 package improve manufacturing yield versus SO14?
The DHVQFN14 (SOT762-1) uses side-wettable flanks that allow automated optical inspection (AOI) to verify solder joint integrity on all 14 terminals - unlike SO14 leads, which require X-ray or ICT for hidden joint validation. This reduces post-reflow defect escape rates and eliminates costly rework in high-volume automotive SMT lines.
