Product details
Overview
74HCU04PW,118 from Nexperia is a hex unbuffered CMOS inverter IC operating across 2.0 V to 6.0 V supply, delivering balanced propagation delays (6 ns typ @ 6.0 V, 50 pF), high noise immunity, and input clamp diodes enabling overvoltage-tolerant interfacing-used in crystal oscillator circuits, linear amplifiers, and astable multivibrators in industrial timing and signal conditioning systems.
For engineers reviewing the 74HCU04PW,118 datasheet, 74HCU04PW,118 pinout, 74HCU04PW,118 application, or 74HCU04PW,118 equivalent, key selection criteria include its unbuffered architecture for low-capacitance node driving, wide temperature range (−40 °C to +125 °C), TSSOP14 package thermal performance, and verified ESD robustness (HBM >2000 V, CDM >1000 V).
Technical Context
The 74HCU04PW,118 implements six independent unbuffered inverters with no internal stage buffering-enabling direct gate-level inversion with minimal propagation delay skew and reduced output capacitance loading. Its CMOS structure provides rail-to-rail output swing and near-zero static current draw.
Input clamp diodes allow safe interface to signals exceeding VCC when used with external current-limiting resistors; latch-up immunity exceeds 100 mA per JESD78 Class II Level B, and operation is specified across −40 °C to +125 °C with full parametric validation at 2.0 V, 4.5 V, 5.0 V, and 6.0 V supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - Enables interoperability with 3.3 V and 5 V logic families and battery-powered systems down to 2 V. |
| Propagation Delay (tpd) | 6 ns typical @ VCC = 6.0 V, CL = 50 pF - Supports high-speed clock distribution and edge-sensitive timing without added buffer latency. |
| Output Drive Strength | ±4.0 mA @ VCC = 4.5 V - Sufficient to drive standard CMOS loads and small capacitive nodes without external buffers. |
| Input Clamp Diodes | Integrated - Permits safe connection of inputs to voltages above VCC using series current-limiting resistors. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets JEDEC JS-001/JS-002 requirements for robust handling in automated assembly and field environments. |
| Operating Temperature | −40 °C to +125 °C - Validated for under-hood automotive auxiliary modules, industrial PLC I/O, and extended-range sensor interfaces. |
| Power Dissipation (Ptot) | 500 mW max (TSSOP14) - Derates linearly at 7.3 mW/K above +81 °C, supporting thermally constrained PCB layouts. |
Pinout & Package
TSSOP14 (SOT402-1) package: plastic thin shrink small outline, 14 leads, body width 4.4 mm, 0.65 mm lead pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (1A–6A) | CMOS-compatible logic inputs with clamp diodes; accept VI up to VCC + 0.5 V when current-limited. |
| 2, 4, 6, 8, 10, 12 | Output (1Y–6Y) | Unbuffered inverting outputs; rail-to-rail swing, ±4 mA drive, low output impedance (~50 Ω typical). |
| 7 | GND | Ground reference for all inputs, outputs, and internal circuitry; must be low-impedance connection. |
| 14 | VCC | Primary power supply pin; decoupling capacitor (100 nF ceramic) required within 5 mm for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered Inverter Architecture | Eliminates internal buffering stages to minimize propagation delay variation and capacitive loading on driven nodes. |
| Wide Supply Range (2.0–6.0 V) | Supports direct integration into mixed-voltage systems without level shifters-e.g., 3.3 V MCU controlling 5 V peripherals. |
| Input Clamp Diodes | Enables safe interfacing to external signals up to VCC + 0.5 V using simple series resistors-no external protection needed. |
| Latch-Up Immunity | Exceeds 100 mA per JESD78 Class II Level B-ensures reliability in noisy industrial environments with transient coupling. |
| High Noise Immunity | VIH ≥ 70% VCC and VIL ≤ 30% VCC across full voltage/temperature range-rejects digital noise on shared PCB traces. |
Applications
| Crystal Oscillator Circuit | Linear Amplifier Stage |
|---|---|
Use Scenario: Generating stable clock signals for microcontrollers or communication peripherals using a parallel-resonant quartz crystal. IC Role / Device Role / Timing Role: Unbuffered inverter configured as gain element in Pierce oscillator topology with external load capacitors and feedback resistor. Use Value: Low input capacitance (3.5 pF) and symmetric transfer characteristics enable reliable oscillation startup and frequency stability across −40 °C to +125 °C. |
Use Scenario: Building low-gain, wide-bandwidth analog amplifiers for sensor signal conditioning or waveform shaping where precision op-amps are over-specified. IC Role / Device Role / Timing Role: Single inverter biased in linear region via feedback network to operate as Class-A amplifier with unity-gain bandwidth ~5 MHz. Use Value: Eliminates need for dedicated op-amp; operates from same supply as digital subsystem, reducing BOM count and layout complexity. |
| Astable Multivibrator | Digital Signal Polarity Correction |
Use Scenario: Generating square-wave clocks or timing pulses in low-power embedded timers, LED flashers, or reset sequencers. IC Role / Device Role / Timing Role: Two unbuffered inverters cross-coupled with RC network to form relaxation oscillator with duty cycle tunable via R/C ratio. Use Value: Propagation delay consistency ensures predictable frequency accuracy; low ICC (<20 μA at VCC = 6 V, static) extends battery life in portable devices. |
Use Scenario: Correcting inverted control signals between legacy peripherals and modern controllers-e.g., active-low enable lines misrouted on PCB. IC Role / Device Role / Timing Role: One or more inverters used as discrete logic polarity inverters with no timing impact due to sub-10 ns delay. Use Value: Pin-compatible replacement for failed 74HC04 sections; unbuffered design avoids overshoot/ringing on fast edges in high-speed bus environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC04PW,118 | Buffered architecture; higher output drive (±5.2 mA); 10 ns tpd @ 4.5 V; no input clamps. | Better for driving heavier capacitive loads but unsuitable for overvoltage-tolerant interfaces or linear amplifier use. | Select when maximum noise margin and load drive are prioritized over input flexibility and low-delay linearity. |
| SN74LVC04APW | 3.3 V only (1.65–3.6 V); lower VCC min; 3.5 ns tpd @ 3.3 V; Schmitt-trigger inputs not included. | Optimized for modern low-voltage digital systems; lacks clamp diodes and extended temperature support. | Choose for cost-sensitive 3.3 V-only designs requiring faster switching but not industrial temperature or overvoltage resilience. |
Compared with 74HC04PW,118 and SN74LVC04APW, the 74HCU04PW,118 uniquely supports both wide-voltage operation and linear-mode applications-making it irreplaceable for crystal oscillators and analog-digital hybrid circuits where unbuffered gain and input clamping are mandatory.

FAQ
Can the 74HCU04PW,118 be used as a linear amplifier?
Yes-the device's unbuffered CMOS structure allows biasing into its linear region using external feedback resistors. Typical applications include low-gain sensor amplifiers and waveform shapers, with unity-gain bandwidth ~5 MHz at VCC = 6.0 V and open-loop gain ~20. Input and output DC operating points must be stabilized per Figure 13 in the datasheet.
What is the purpose of the input clamp diodes?
The integrated input clamp diodes protect against voltages exceeding VCC or falling below GND by shunting excess current through external series resistors. This enables safe interfacing with signals up to VCC + 0.5 V without external protection components-critical in mixed-voltage system interconnects.
How does the TSSOP14 package affect thermal performance?
The SOT402-1 (TSSOP14) package has a thermal resistance of 7.3 mW/K above +81 °C, meaning total power dissipation derates linearly beyond that ambient. At 100 °C ambient, Ptot drops to ~485 mW. PCB copper area under the exposed pad improves heat spreading but the pad is not electrically connected.
Is the 74HCU04PW,118 suitable for automotive applications?
No-it is not AEC-Q100 qualified. While rated for −40 °C to +125 °C, Nexperia explicitly states non-automotive qualification unless otherwise specified. For automotive use, consider the pin-compatible AEC-Q100 qualified 74HCU04-Q100 variants with validated reliability testing per automotive standards.
