Product details
Overview
74HC1GU04GV,125 from Nexperia is a single unbuffered CMOS inverter in SC-74A (SOT753) package with 5 terminals, operating from 2.0 V to 6.0 V supply, delivering symmetrical output impedance, balanced propagation delays (6–15 ns at VCC = 6.0 V, CL = 50 pF), and rated for -40 °C to +125 °C ambient. It serves as a logic-level signal inverter or linear amplifier stage in low-power timing and oscillator circuits.
For engineers reviewing the 74HC1GU04GV,125 datasheet, 74HC1GU04GV,125 pinout, 74HC1GU04GV,125 application, or 74HC1GU04GV,125 equivalent, key selection criteria include input clamping diode support for overvoltage-tolerant interfacing, ±12.5 mA output drive capability, 5-pin SC-74A footprint compatibility, and validated use in crystal oscillator topologies up to 600 kHz.
Technical Context
This device implements a single-stage CMOS inverter without internal buffering, enabling direct use in high-impedance feedback paths. Its input clamp diodes allow safe interface to signals exceeding VCC when used with current-limiting resistors - a critical feature for mixed-voltage system interconnects.
The unbuffered architecture yields low input capacitance (5 pF typical), fast propagation delay (as low as 6 ns at VCC = 6.0 V), and predictable transfer characteristics suitable for linear-mode operation in crystal oscillators and analog amplifiers - confirmed by typical gfs = 20 mA/V at VCC = 4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports dual-rail systems and battery-powered designs down to 2 V without level-shifting. |
| Propagation Delay (tpd) | 6 ns (typ.) at VCC = 6.0 V, CL = 50 pF - enables reliable 100+ MHz clock edge generation in oscillator loops. |
| Output Drive Current | ±12.5 mA - sufficient to directly drive 50-pF loads and small capacitive crystals without external buffers. |
| Input Clamp Diodes | Integrated - permits safe interface to voltages > VCC using series current-limiting resistors (e.g., 560 kΩ bias in oscillator config). |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial control environments. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - robust handling during PCB assembly and field service without additional protection circuitry. |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 85 °C (SOT753) - derates linearly at 3.8 mW/K above 85 °C, supporting thermal-aware layout. |
Pinout & Package
SC-74A (SOT753) plastic surface-mounted package: 5-lead, body size 3.1 mm × 1.7 mm × 1.3 mm, pitch 0.95 mm, no thermal pad. Pin 1 indicator located below marking "HU4" at lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - electrically isolated; must be left floating or tied to GND per layout best practice. |
| 2 | A | Inverting input - accepts TTL/CMOS logic levels; clamp diodes enable overvoltage tolerance with external resistor. |
| 3 | GND | Ground reference - primary return path for supply and signal currents; requires low-inductance PCB connection. |
| 4 | Y | Inverted output - drives downstream logic or crystal network; symmetrical impedance ensures clean rise/fall times. |
| 5 | VCC | Positive supply - decoupling capacitor (100 µF + 0.47 µF) recommended per Fig. 7 for stable linear-mode operation. |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered Inverter Topology | Enables direct integration into Pierce oscillator feedback loops without added phase shift or gain stages. |
| Symmetrical Output Impedance | Ensures matched rise/fall times (<15% skew) critical for low-jitter clock generation in crystal circuits. |
| Wide Supply Range (2.0–6.0 V) | Eliminates need for voltage translators in multi-supply systems (e.g., 3.3 V MCU interfacing to 5 V peripherals). |
| Latch-up Immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events. |
| Low Input Capacitance | 5 pF typical - minimizes loading on high-frequency crystal resonators and preserves loop gain stability. |
Applications
| Crystal Oscillator Core | Level-Shifting Interface |
|---|---|
Use Scenario: Generating stable clock signals for microcontrollers or real-time clocks using a parallel-resonant quartz crystal (e.g., 32.768 kHz or 1 MHz). IC Role / Device Role / Timing Role: Active inverter element in a Pierce oscillator configuration, providing 180° phase shift and gain to sustain oscillation. Use Value: Eliminates need for discrete transistors or dedicated oscillator ICs; supports frequency tuning via external R1/R2/C1/C2 per Table 9. |
Use Scenario: Interfacing a 5 V sensor output to a 3.3 V microcontroller GPIO with overvoltage protection. IC Role / Device Role / Timing Role: Logic-level translator with built-in input clamp diodes, used with 10 kΩ series resistor on input. Use Value: Prevents damage from 5 V signals applied to 3.3 V inputs while maintaining full logic swing and <10 ns delay penalty. |
| Analog Signal Inversion | Power-On Reset Conditioning |
Use Scenario: Converting inverted analog sensor outputs (e.g., differential pressure transducer) into positive-swing signals for ADC input. IC Role / Device Role / Timing Role: Linear-mode amplifier biased via R1/R2 network (Fig. 12), operating at DC or low-frequency AC. Use Value: Delivers open-loop gain ~20 and unity-gain bandwidth ~5 MHz - sufficient for anti-aliasing filtering and offset correction. |
Use Scenario: Debouncing and inverting a mechanical reset switch signal before feeding to an FPGA or ASIC reset controller. IC Role / Device Role / Timing Role: Schmitt-trigger-capable inverter (via external hysteresis resistors) cleaning noisy switch transitions. Use Value: Provides noise immunity >300 mV at VCC = 5 V and propagation delay <21 ns - meets fast-reset timing budgets in safety-critical systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unbuffered inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G04GW,125 | Lower VCC range (1.65–5.5 V); higher speed (tpd = 3.1 ns @ VCC = 3.3 V); no input clamp diodes. | Not suitable for overvoltage-tolerant interfaces; preferred in 3.3 V-only high-speed digital logic. | Select when speed >6 ns and overvoltage protection is unnecessary; verify VIH/VIL thresholds match host logic family. |
| SN74AUP1G04DBVR | Ultra-low power (ICC = 0.9 μA typ.); wider temp range (-40 °C to +125 °C); no clamp diodes; VCC = 0.8–3.6 V. | Cannot interface to >3.6 V signals; optimized for battery-powered IoT sensors, not oscillator circuits. | Choose for sub-μA standby current in portable devices; avoid where crystal drive or >3.6 V interfacing is required. |
Compared with 74HC1GU04GV,125, the LVC variant trades overvoltage tolerance for speed in 3.3 V systems, while the AUP variant sacrifices drive strength and voltage range for nanoamp quiescent current - making the HC version uniquely suited for mixed-voltage oscillator and interface roles.

FAQ
Can 74HC1GU04GV,125 be used in linear amplifier mode?
Yes - its unbuffered CMOS structure allows stable linear operation when DC-biased via resistive network (R1/R2 per Fig. 12). Typical open-loop gain is 20, unity-gain bandwidth ~5 MHz, and it supports rail-to-rail output swing centered at 0.5 × VCC. Biasing must follow datasheet guidelines to avoid thermal runaway.
What is the purpose of the n.c. pin (Pin 1) in SOT753?
Pin 1 is internally not connected - no bond wire or silicon connection exists. It must remain unconnected or tied to GND for mechanical stability and EMI reduction. Do not route signals or supply lines to this pin, as it provides no electrical function and has no internal termination.
How does the input clamp diode affect interface design?
The integrated clamp diodes allow safe connection of input signals up to VCC + 0.5 V (or down to GND − 0.5 V) when used with a series current-limiting resistor. For example, a 5 V signal can drive the A input when Rlimit ≥ 10 kΩ at VCC = 3.3 V - preventing latch-up and eliminating need for external protection diodes.
Is 74HC1GU04GV,125 qualified for automotive applications?
No - although rated for -40 °C to +125 °C ambient, it is not AEC-Q100 qualified and lacks automotive-specific stress testing, failure analysis, or PPAP documentation. Nexperia explicitly states non-automotive qualification in legal disclaimers; use only in industrial or consumer systems unless separately validated by the end customer.
