Product details
Overview
74AHC3GU04DC,125 from Nexperia is a triple unbuffered CMOS inverter IC with overvoltage-tolerant inputs (up to 5.5 V), operating across 2.0–5.5 V supply range, delivering symmetrical output impedance and balanced propagation delays (≤10.0 ns at VCC = 5.5 V, CL = 15 pF). It enables voltage translation in mixed-supply systems and supports industrial temperature operation up to +125 °C.
For engineers reviewing the 74AHC3GU04DC,125 datasheet, 74AHC3GU04DC,125 pinout, 74AHC3GU04DC,125 application, or 74AHC3GU04DC,125 equivalent, key selection criteria include input overvoltage tolerance, propagation delay consistency across supply voltages, unbuffered gate behavior for oscillator design, and VSSOP8 package compatibility with high-density PCB layouts.
Technical Context
This device implements three independent unbuffered inverters-each with no internal buffering stage-enabling direct use in crystal oscillator feedback loops and linear amplifier configurations. Its CMOS input structure provides high noise immunity and low input leakage (<2.0 μA), while symmetrical drive capability ensures matched rise/fall times.
The unbuffered architecture yields non-rail-to-rail transfer characteristics and enables stable oscillation when biased with external resistors and capacitors. Input overvoltage tolerance (VI ≤ 5.5 V independent of VCC) permits interfacing between 3.3 V logic and 5 V peripherals without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - Enables single-supply operation across 3.3 V and 5 V systems without regulator dependency. |
| Input Overvoltage Tolerance | Up to 5.5 V - Allows safe connection to higher-voltage signals even when VCC = 2.0 V, simplifying mixed-voltage interface design. |
| Propagation Delay (max) | 10.0 ns at VCC = 5.5 V, CL = 15 pF - Guarantees timing predictability in clock distribution and signal inversion paths. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive modules and industrial control environments requiring extended thermal margin. |
| Output Drive Strength | ±8.0 mA at VCC = 4.5 V - Sufficient to drive 15–50 pF loads directly, supporting fan-out into multiple CMOS inputs or small capacitive traces. |
| Power Dissipation Capacitance | 4 pF per buffer - Enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for low-power battery-operated designs. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets IEC 61000-4-2 Level 2 requirements, reducing need for external protection in handheld and field-deployable equipment. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 | 1A, 2A, 3A | Independent logic inputs - Each drives one unbuffered inverter stage; tolerant to 5.5 V regardless of VCC setting. |
| 2, 5, 7 | 3Y, 1Y, 2Y | Respective inverted outputs - Pin 2 = 3Y, Pin 5 = 1Y, Pin 7 = 2Y per functional diagram; outputs swing rail-to-rail within VCC/GND limits. |
| 4 | GND | Ground reference - Must be connected to system 0 V plane; serves as return path for all three gates' current flow. |
| 8 | VCC | Supply voltage input - Powers all three inverters; decoupling capacitor (≥100 nF) required adjacent to this pin for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | Enables matched rise/fall times (tPLH ≈ tPHL), critical for minimizing duty-cycle distortion in clock generation circuits. |
| Unbuffered gate architecture | Permits direct use in Pierce crystal oscillator topologies (Fig. 10) without added phase shift from internal buffers. |

| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - Eliminates risk of destructive latch-up during transient overvoltage events in noisy industrial environments. |
| CMOS low power dissipation | ICC ≤ 40 μA at VCC = 5.5 V - Enables integration into always-on subsystems (e.g., real-time clock supervisors) with negligible quiescent current impact. |
Applications
| Crystal Oscillator Circuit | Level Translation Interface |
|---|---|
|
Use Scenario: Generating stable clock signals for microcontrollers or sensors using a parallel-resonant quartz crystal. IC Role / Device Role / Timing Role: Unbuffered inverter configured as gain element in Pierce oscillator topology, with external R1/R2 biasing and C1/C2 load capacitors. Use Value: Eliminates need for dedicated oscillator ICs; supports frequencies from 3 kHz to 600 kHz with typical ICC < 2 mA at VCC = 3 V. |
Use Scenario: Interfacing 5 V legacy peripherals (e.g., UART transceivers) with 3.3 V microcontrollers in mixed-voltage embedded systems. IC Role / Device Role / Timing Role: Inverting level translator where input can exceed VCC without damage, enabling bidirectional signal conditioning without external MOSFETs. Use Value: Reduces BOM count by replacing discrete resistor-divider or dedicated level shifter ICs; maintains full-speed digital signaling (≤10 ns delay). |
| Linear Amplifier Stage | Signal Polarity Correction |
|
Use Scenario: Building low-gain analog amplifiers for sensor signal conditioning where rail-to-rail swing and low distortion are required. IC Role / Device Role / Timing Role: Biased in linear region using feedback resistors (R1 ≥ 3 kΩ, R2 ≤ 1 MΩ) to operate as open-loop amplifier with Gol ≈ 20. Use Value: Provides unity-gain bandwidth of ~5 MHz and maximum Vo(p-p) = VCC − 1.5 V centered at 0.5 × VCC - suitable for audio pre-amplification or analog front-end buffering. |
Use Scenario: Correcting inverted logic states in FPGA configuration chains or debug trace signal routing where signal polarity must be flipped without timing skew. IC Role / Device Role / Timing Role: Triple inverter providing three independent, low-skew polarity inversions for parallel data bus lines (e.g., JTAG TMS/TCK or SPI MISO/MOSI paths). Use Value: Delivers matched tPLH/tPHL across all three channels (≤1.0 ns skew), ensuring deterministic setup/hold timing in high-speed serial protocols. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unbuffered inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC3GU04GW,125 | Lower VCC range (1.65–5.5 V); higher ICC (≤100 μA); same VSSOP8 package. | Not rated for operation below 1.65 V; less suitable for 1.8 V-only systems requiring ultra-low ICC. | Select when tighter input threshold matching (VIH/VIL) at 1.8 V is required, but accept higher quiescent current. |
| SN74AUP3G04DCUR | Narrower VCC range (0.8–3.6 V); lower CPD (2.5 pF); max tpd = 11.5 ns at 3.3 V. | Cannot support 5 V interfaces; optimized for sub-3.3 V portable electronics with strict power budgets. | Prefer for battery-powered IoT nodes where 0.8–3.6 V operation and <1 μA ICC are mandatory, but avoid for 5 V mixed-signal systems. |
Compared with 74AHC3GU04DC,125, the LVC variant trades lower minimum supply for higher static current, while the AUP variant sacrifices 5 V compatibility for ultra-low power at sub-2 V operation-making the AHC version uniquely balanced for industrial mixed-voltage designs requiring robustness, speed, and wide supply flexibility.

FAQ
Can 74AHC3GU04DC,125 be used as a linear amplifier?
Yes-it is explicitly characterized for linear operation in its datasheet (Section 12, Fig. 9). When DC-biased with R1 ≥ 3 kΩ and R2 ≤ 1 MΩ, it delivers open-loop gain ≈20 and unity-gain bandwidth ~5 MHz. Output swing is limited to VCC − 1.5 V peak-to-peak, centered at 0.5 × VCC, making it suitable for low-distortion sensor signal conditioning.
What is the maximum clock frequency achievable in a crystal oscillator using this device?
The device supports crystal oscillator operation up to 600 kHz (per Table 11), with optimal R1/R2/C1/C2 values provided for frequencies from 10 kHz to 600 kHz. At higher frequencies, stability degrades due to reduced loop gain; for >1 MHz, a buffered inverter or dedicated oscillator IC is recommended.
Does the VSSOP8 package (SOT765-1) have the same pinout as TSSOP8 (SOT505-2)?
Yes-both packages share identical pin numbering and functional assignment: pins 1/3/6 = inputs (1A/2A/3A), pins 2/5/7 = outputs (3Y/1Y/2Y), pin 4 = GND, pin 8 = VCC. Mechanical dimensions differ (VSSOP8 body width = 2.3 mm vs. TSSOP8 = 3 mm), but PCB layout is pin-compatible with adjusted land patterns.
How does input overvoltage tolerance function when VCC = 2.0 V?
Inputs tolerate up to 5.5 V regardless of VCC value, enabled by internal clamping structures that route excess voltage to VCC or GND via controlled current paths. This allows safe connection to 5 V signals while powering the device from 2.0 V-no external diodes or resistors needed-verified per Section 8 limiting values (VI ≤ +7.0 V absolute max).
