Product details
Overview
74HCU04D-Q100 from Nexperia is a hex unbuffered CMOS inverter qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0 V to 6.0 V, featuring input clamp diodes enabling overvoltage-tolerant interfacing and balanced propagation delays of 6 ns (typ) at VCC = 6.0 V/CL = 50 pF.
For engineers reviewing the 74HCU04D-Q100 datasheet, 74HCU04D-Q100 pinout, 74HCU04D-Q100 application, or 74HCU04D-Q100 equivalent, this device serves as a robust logic-level inversion element in automotive body control modules, sensor signal conditioning circuits, and crystal oscillator bias networks where rail-to-rail swing, low static current (<2 μA), and high noise immunity are required.
Technical Context
This unbuffered inverter uses standard CMOS topology without internal buffering stages, delivering symmetrical rise/fall times (6 ns typ) and high DC noise margins - VIH min = 3.6 V and VIL max = 0.9 V at VCC = 4.5 V. Input clamp diodes allow safe interface to signals exceeding VCC when used with current-limiting resistors.
It supports linear-mode operation (e.g., crystal oscillators, astable multivibrators) due to its high open-loop gain (~20) and transconductance (gfs ≈ 40 mA/V at VCC = 6.0 V), while maintaining rail-compatible output swing (VOH ≥ 5.48 V, VOL ≤ 0.26 V at VCC = 6.0 V/IO = ±5.2 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - Enables direct interface with 3.3 V and 5 V systems, plus legacy 2.5 V and 6 V automotive rails. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications. |
| Propagation Delay | 6 ns (typ) at VCC = 6.0 V/CL = 50 pF - Supports reliable timing in clock distribution and feedback loops up to ~50 MHz. |
| Output Drive Strength | ±5.2 mA at VCC = 6.0 V - Sufficient to drive 50 pF loads directly or fan out to ≥10 standard CMOS inputs. |
| Input Leakage Current | ±0.1 μA (max) at VCC = 6.0 V - Minimizes loading on high-impedance sources such as crystal resonators or RC timing networks. |
| Power Dissipation Capacitance | 10 pF per inverter - Enables accurate dynamic power estimation: PD = CPD × VCC² × fi × N. |
Pinout & Package
74HCU04D-Q100 is housed in SO14 (SOT108-1): plastic small outline package, 14 leads, 3.9 mm body width, with gull-wing leads and pin 1 index marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | CMOS digital inputs with integrated clamp diodes - tolerate VI < -0.5 V or VI > VCC + 0.5 V when current-limited. |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Inverting outputs with rail-to-rail swing; capable of sourcing/sinking ±5.2 mA at VCC = 6.0 V. |
| 7 | GND | Ground reference for all I/O and internal circuitry; must be low-impedance connection in automotive PCB layout. |
| 14 | VCC | Primary supply pin; decoupling capacitor (100 nF ceramic) required within 5 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive ambient temperatures (-40 °C to +125 °C) and lifetime reliability per JEDEC JESD47. |
| Input clamp diodes | Enable safe interfacing to voltages beyond VCC using external current-limiting resistors - critical for mixed-voltage sensor interfaces. |
| Low static current | ICC ≤ 2 μA (typ) at VCC = 6.0 V - reduces quiescent power in always-on vehicle subsystems like door modules. |
| High noise immunity | VIH/VIL margins exceed 40% of VCC across full temperature range - suppresses false triggering in electrically noisy engine bays. |
| Side-wettable flanks (in Q100 variants) | SO14 variant supports AOI solder-joint inspection - improves manufacturing yield in automotive Tier-1 assembly lines. |
Applications
| Body Control Module Signal Inversion | Crystal Oscillator Bias Network |
|---|---|
|
Use Scenario: Level-shifting and polarity correction of wake-up signals from door latch switches or seat occupancy sensors before MCU GPIO input. IC Role / Device Role / Timing Role: Unbuffered inverter provides clean, fast edge transitions with minimal added delay (6 ns typ), preserving timing integrity in low-power sleep/wake sequences. Use Value: Clamp diodes eliminate need for external protection diodes, reducing BOM count and PCB area in space-constrained junction boxes. |
Use Scenario: Providing gain and phase inversion in Pierce-type crystal oscillator circuits for engine control unit (ECU) real-time clocks. IC Role / Device Role / Timing Role: Operates in linear region to sustain oscillation; high transconductance (40 mA/V) ensures reliable start-up across temperature and aging. Use Value: Single-device oscillator solution avoids dedicated oscillator ICs - lowers cost and simplifies qualification for ASIL-B timing paths. |
| Astable Multivibrator Timer | LED Driver Logic Interface |
|
Use Scenario: Generating periodic enable pulses for HVAC blower motor control or interior lighting dimming waveforms. IC Role / Device Role / Timing Role: Two inverters form RC-based relaxation oscillator; propagation delay stability ensures consistent frequency drift <±5% over -40 °C to +125 °C. Use Value: Eliminates discrete transistor timers; low ICC enables battery-backed operation during vehicle ignition-off states. |
Use Scenario: Inverting PWM signals from microcontroller to match active-low enable logic of LED driver ICs in dashboard backlighting. IC Role / Device Role / Timing Role: Provides precise logic inversion with matched rise/fall times (6 ns), preventing shoot-through in cascaded driver stages. Use Value: Rail-compatible VOH/VOL ensures full logic swing into driver enable pins - guarantees reliable turn-on/turn-off even at 2.0 V supply. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCU04QPWRQ1 | TI's AEC-Q100 Grade 1 hex unbuffered inverter in TSSOP-14; identical VCC range and temp grade but higher ICC (5 μA typ) and slower tpd (10 ns typ @ 6 V). | Less suitable for ultra-low-power always-on nodes; requires larger decoupling due to higher dynamic current. | Select when existing TI-qualified BOM mandates vendor consistency or TSSOP footprint is preferred. |
| 74LVC04BQ-Q100 | Nexperia's buffered LVC variant in DHVQFN14; lower VCC range (1.65–5.5 V), faster tpd (3.2 ns), but no input clamps and reduced noise margin (VIL = 0.58 V @ 3.3 V). | Not suitable for overvoltage-tolerant interfaces or 6 V systems; requires external ESD protection in harsh environments. | Select only for high-speed 3.3 V-only designs where board space is constrained and clamping is unnecessary. |
Compared with SN74HCU04QPWRQ1, the 74HCU04D-Q100 offers lower static power and tighter propagation delay matching; versus 74LVC04BQ-Q100, it trades speed for robustness in mixed-voltage automotive domains requiring clamp diodes and 6 V operation.

FAQ
Can 74HCU04D-Q100 operate reliably at 2.0 V supply?
Yes - it is fully specified from 2.0 V to 6.0 V. At 2.0 V, VIH min = 1.7 V and VOL max = 0.3 V ensure valid CMOS logic levels, and propagation delay remains within 70 ns (max) at -40 °C to +85 °C, supporting low-voltage battery monitoring circuits.
Does this device support linear amplifier operation?
Yes - its unbuffered architecture and high open-loop gain (~20) enable stable linear-mode use. Application note figures show functional crystal oscillators and astable multivibrators, with typical unity-gain bandwidth of 5 MHz at VCC = 6.0 V.
What is the purpose of the "VCC(1)" pad in DHVQFN packages?
In SOT762-1 (DHVQFN14), terminal 1 is a thermal pad labeled "VCC(1)" - not an electrical supply pin. It may remain floating or connect to VCC for improved thermal conduction, but has no electrical requirement for soldering or biasing.
How does input clamping affect interface design with 12 V sensors?
Clamp diodes allow direct connection to 12 V signals when paired with a series current-limiting resistor (e.g., 10 kΩ limits IIK to <1.2 mA at 12 V). This eliminates level-shifters in LIN bus wake-up or switch monitoring circuits, provided resistor power rating and layout meet AEC-Q200 requirements.
