Product details
Overview
74AHCU04PW,112 from Nexperia is a high-speed Si-gate CMOS hex unbuffered inverter with six independent single-stage inverters, pin-compatible with LSTTL, operating from -40 °C to +125 °C, supporting VCC = 2.0–5.5 V, and delivering tpd ≤ 7.0 ns (VCC = 5.0 V, CL = 50 pF) for digital logic inversion in timing-critical control paths.
For engineers reviewing the 74AHCU04PW,112 datasheet, 74AHCU04PW,112 pinout, 74AHCU04PW,112 application, or 74AHCU04PW,112 equivalent, this device serves as a robust, temperature-hardened logic inverter for clock buffering, oscillator feedback, and level-shifting in industrial control, sensor interface, and power management subsystems.
Technical Context
The 74AHCU04PW,112 implements six identical unbuffered CMOS inverter stages-each with no internal buffering-enabling direct gate-level inversion with minimal propagation delay asymmetry (tpd tPLH ≈ tPHL). Its input structure accepts voltages up to 7.0 V regardless of VCC, supporting mixed-voltage interfacing.
It features ESD protection per JS-001 (HBM > 2000 V) and JS-002 (CDM > 1000 V), operates across full industrial temperature range (-40 °C to +125 °C), and maintains VIH/VIL thresholds tightly specified across VCC = 2.0–5.5 V, ensuring reliable switching in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - Enables operation across 3.3 V and 5 V logic domains without level shifters. |
| tpd (Max) | 9.0 ns at VCC = 4.5–5.5 V, CL = 50 pF - Guarantees sub-10 ns signal inversion for high-speed control loops. |
| VIH / VIL | VIH = 4.4 V (min), VIL = 1.1 V (max) at VCC = 5.5 V - Ensures noise margins > 0.9 V under worst-case supply and temp. |
| VOH / VOL | VOH = 3.7 V (min), VOL = 0.55 V (max) at IO = ±8.0 mA - Sustains TTL- and CMOS-compatible output swing under load. |
| Operating Temp | -40 °C to +125 °C - Qualified for under-hood, motor drive, and industrial PLC applications. |
| ESD Rating | HBM > 2000 V, CDM > 1000 V - Reduces field failure risk during handling and board assembly. |
| Input Leakage | ≤ 2.0 μA at VI = 5.5 V - Minimizes loading on high-impedance sources like crystal networks or sensor outputs. |
Pinout & Package
TSSOP14 plastic thin shrink small outline package (SOT402-1); 14-lead, 4.4 mm body width, 0.65 mm lead pitch; thermally enhanced for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data Input (1A–6A) | CMOS-compatible inputs accepting voltages up to 7.0 V - enables overvoltage-tolerant interfacing with legacy or mixed-supply systems. |
| 2, 4, 6, 8, 10, 12 | Data Output (1Y–6Y) | Push-pull CMOS outputs capable of ±8.0 mA drive - supports fan-out to multiple loads without external buffers. |
| 7 | GND | Primary ground reference for all logic and power domains - must be low-impedance for stable noise immunity. |
| 14 | VCC | Single-supply rail (2.0–5.5 V) powering all six inverters - decoupling capacitor required within 10 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered Inverter Architecture | Single-stage CMOS topology minimizes propagation delay variation (tpd tPLH ≈ tPHL) and eliminates internal phase shifts critical for oscillator feedback. |
| Overvoltage-Tolerant Inputs | Accepts VI up to 7.0 V independent of VCC - allows safe interfacing with 5 V signals into 3.3 V systems without clamping diodes. |
| Wide Temperature Operation | Specified from -40 °C to +125 °C - ensures consistent timing and logic integrity in automotive engine control, industrial drives, and outdoor equipment. |
| Low Static Power | ICC ≤ 40 μA at VCC = 5.5 V - reduces quiescent current in always-on monitoring circuits and battery-backed subsystems. |
| High ESD Robustness | HBM > 2000 V, CDM > 1000 V - meets IEC 61000-4-2 system-level ESD requirements without additional protection components. |
Applications
| Crystal Oscillator Feedback | Digital Signal Level Shifting |
|---|---|
|
Use Scenario: Used in Pierce oscillator configurations with quartz crystals (e.g., 32.768 kHz or 1–20 MHz) to generate stable clock references for microcontrollers and RTCs. IC Role / Device Role / Timing Role: Provides high-gain, low-phase-noise inverting amplification in the oscillator loop - unbuffered design avoids added delay that degrades start-up reliability. Use Value: Enables self-starting oscillation with typical R1 = 1–10 MΩ and C1/C2 = 5–56 pF, eliminating need for discrete transistors or dedicated oscillator ICs. |
Use Scenario: Translating logic levels between 5 V microcontroller GPIO and 3.3 V peripheral interfaces (e.g., UART, SPI, I²C pull-up domains). IC Role / Device Role / Timing Role: Acts as bidirectional voltage translator via input overvoltage tolerance and rail-referenced outputs - no external bias required. Use Value: Supports clean, glitch-free level translation at up to 10 MHz (CL = 15 pF), reducing BOM count versus dedicated level shifter ICs. |
| Linear Amplifier Stage | Power Sequencing Control |
|
Use Scenario: Configured as a high-gain linear amplifier (e.g., in sensor front-ends or analog comparators) using external resistive feedback. IC Role / Device Role / Timing Role: Functions as a rail-to-rail CMOS amplifier with open-loop gain ~12 and unity-gain bandwidth ~5 MHz - enabled by unbuffered gain stage. Use Value: Delivers low-distortion amplification (Vo(p-p) ≤ VCC − 1.5 V, centered at 0.5 × VCC) without op-amp biasing complexity or cost. |
Use Scenario: Generating precise enable/disable timing sequences for multi-rail power supplies (e.g., FPGA core, I/O, and auxiliary rails) in embedded systems. IC Role / Device Role / Timing Role: Inverts and delays control signals to stagger turn-on/turn-off edges - six independent channels allow compact sequencing logic. Use Value: Achieves <10 ns channel-to-channel skew and <9 ns max propagation delay, enabling sub-microsecond sequencing accuracy without FPGA logic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC04PW,118 | Lower VCC range (1.65–5.5 V); higher ICC (≤ 40 μA vs. ≤ 20 μA at 25 °C); tpd ≤ 5.0 ns (CL = 50 pF, VCC = 3.3 V) | Better suited for 1.8 V/2.5 V systems; less robust at 125 °C (only rated to +125 °C with derated drive) | Select when operating below 2.0 V or requiring faster speed at 3.3 V; verify thermal performance in high-temp enclosures. |
| SN74HC04PWR | Same pinout; wider VCC (2–6 V); higher tpd (≤ 18 ns at CL = 50 pF, VCC = 4.5 V); no overvoltage-tolerant inputs | Limited to 85 °C ambient; lacks HBM > 2000 V rating; unsuitable for direct 5 V-to-3.3 V interfacing | Choose only for cost-sensitive commercial-grade designs where temperature and ESD stress are negligible. |
Compared with 74LVC04PW,118 and SN74HC04PWR, the 74AHCU04PW,112 uniquely combines overvoltage-tolerant inputs, full -40 °C to +125 °C qualification, and sub-10 ns propagation delay - making it the only option qualified for ruggedized timing-critical industrial and automotive-adjacent applications.

FAQ
Can the 74AHCU04PW,112 be used as a linear amplifier?
Yes - its unbuffered CMOS inverter stage can operate in the linear region when DC-biased with appropriate feedback resistors (R1 ≥ 3 kΩ, R2 ≤ 1 MΩ). Typical open-loop gain is 12, with unity-gain bandwidth near 5 MHz and maximum output swing of VCC − 1.5 V centered at 0.5 × VCC, as validated in Figure 11 of the datasheet.
What is the maximum recommended capacitive load per output?
The datasheet specifies dynamic characteristics up to CL = 50 pF, with tpd increasing predictably beyond that. While not explicitly limited, sustained loading above 50 pF risks exceeding the 9.0 ns max tpd specification and may degrade waveform fidelity; for loads > 50 pF, buffer stages or lower-impedance drivers are advised.
Does the TSSOP14 package (SOT402-1) require thermal pad soldering?
No - unlike QFN packages, the TSSOP14 has no exposed thermal pad. The SOT402-1 outline defines standard gull-wing leads only; thermal dissipation relies on copper pour under the body and trace routing, with Ptot derating beginning at 81 °C at 7.3 mW/K.
Is the 74AHCU04PW,112 suitable for automotive applications?
It is not AEC-Q100 qualified and is explicitly designated as non-automotive in Nexperia's legal disclaimers. While it operates from -40 °C to +125 °C, it lacks automotive-specific testing (e.g., HTOL, ESD system-level validation), so use in safety-critical vehicle systems is not supported.
