Product details

Overview

74AHC1GU04GV,125 from Nexperia is a single unbuffered CMOS inverter with overvoltage-tolerant inputs (up to 5.5 V), operating across 2.0–5.5 V supply range and specified from −40 °C to +125 °C. It delivers symmetrical output impedance, 7.0 ns typical propagation delay at 5 V/50 pF, and supports mixed-voltage level translation in compact SC-74A (SOT753) packaging. Used in crystal oscillator circuits and linear amplifier configurations.

For engineers reviewing the 74AHC1GU04GV,125 datasheet, 74AHC1GU04GV,125 pinout, 74AHC1GU04GV,125 application, or 74AHC1GU04GV,125 equivalent, this page provides verified functional role, validated pin mapping for SOT753, real-world oscillator and level-shifting use cases, and direct comparison against two field-validated alternatives - all derived from Nexperia's Rev. 8 product data sheet dated 9 September 2025.

Technical Context

This device implements a single unbuffered inverter gate with no internal buffering stage, resulting in lower propagation delay but higher sensitivity to capacitive loading compared to buffered variants. Its overvoltage-tolerant inputs enable direct interfacing between 3.3 V logic and 5 V systems without external level-shifters.

The logic function is strictly inverting (L→H, H→L), with rail-to-rail output swing and symmetrical drive capability (±8 mA at V_CC = 4.5 V). It supports operation up to 125 °C ambient and meets JESD 78 Class II Level A latch-up immunity (>100 mA).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	2.0 V to 5.5 V - enables interoperability across 2.5 V, 3.3 V, and 5 V logic domains
Input voltage tolerance	Up to 5.5 V independent of V_CC - allows safe connection to higher-voltage buses without clamping diodes
Propagation delay	7.0 ns max at V_CC = 5.0 V, C_L = 50 pF - suitable for sub-100 MHz clock distribution and oscillator feedback paths
Output drive	±8.0 mA at V_CC = 4.5 V - sufficient to drive 50 pF loads directly or bias crystal resonators
Operating temperature	−40 °C to +125 °C - qualified for under-hood automotive modules and industrial control environments
Power dissipation	250 mW max at T_amb ≤ 85 °C - derates linearly at 3.8 mW/K above 85 °C in SOT753 package
Input capacitance	10 pF max - minimizes loading on upstream drivers and stabilizes oscillator loop gain

Pinout & Package

74AHC1GU04GV,125 is housed in SC-74A (SOT753), a 5-terminal plastic surface-mounted package measuring 3.1 mm × 1.7 mm × 1.3 mm with gull-wing leads and 0.95 mm lead pitch.

Pin/Terminal	Circuit Role	Design Meaning
1	Not connected (n.c.)	No internal bond; must remain floating - avoids unintended parasitic coupling or ESD path
2	Data input (A)	Overvoltage-tolerant CMOS input accepting 0–5.5 V regardless of V_CC
3	Ground (GND)	Reference node for all I/O and supply; requires low-inductance PCB connection for noise immunity
4	Data output (Y)	Inverted copy of A with rail-to-rail swing and symmetrical sourcing/sinking capability
5	Supply voltage (V_CC)	Primary power rail; decoupling capacitor (≥100 nF) required within 3 mm for stable high-speed switching

Key Features

Feature	Design Value
Wide supply range	2.0–5.5 V operation eliminates need for separate voltage regulators in multi-rail systems
Overvoltage-tolerant inputs	Accepts 5.5 V inputs even at V_CC = 2.0 V - enables robust level translation without external components
Symmetrical output impedance	Matched pull-up/pull-down strength ensures consistent rise/fall times and reduces duty-cycle distortion
High noise immunity	Typical V_IL = 0.6 V and V_IH = 2.4 V at V_CC = 3.0 V - provides >0.9 V noise margin in 3.3 V systems
Industrial temperature grade	−40 °C to +125 °C operation supports deployment in motor drives, power supplies, and outdoor infrastructure

Applications

Crystal Oscillator

Level Translation

Use Scenario: Forms the gain element in Pierce-type crystal oscillator circuits for generating stable clock signals between 3 kHz and 600 kHz.

IC Role / Device Role / Timing Role: Unbuffered inverter provides phase inversion and gain in the oscillator loop; R1/R2 bias network sets DC operating point per Fig. 12.

Use Value: Low input capacitance (10 pF) and predictable propagation delay stabilize oscillation frequency; ICC ≈ 2 mA at 1 MHz enables low-power timing reference generation.

Use Scenario: Interfaces 5 V microcontroller GPIO to 3.3 V sensor interface while maintaining signal integrity.

IC Role / Device Role / Timing Role: Single-gate inverter acts as bidirectional level translator via overvoltage-tolerant input and CMOS output swing referenced to local V_CC.

Use Value: Eliminates need for dedicated level-shifter ICs; supports hot-swap compatibility and mixed-voltage board design without additional passives.

Linear Amplifier

Signal Inversion

Use Scenario: Configured as a low-gain linear amplifier for analog sensor signal conditioning in battery-powered IoT nodes.

IC Role / Device Role / Timing Role: Operated in analog region using external bias resistors (R1 ≥ 3 kΩ, R2 ≤ 1 MΩ) per Fig. 11 to achieve open-loop gain ≈ 20.

Use Value: Enables reuse of digital logic IC for analog functions; typical unity-gain bandwidth of 5 MHz supports audio-band and slow-control applications.

Use Scenario: Inverts control signals in PLC I/O modules where active-low enable logic is required for relay drivers.

IC Role / Device Role / Timing Role: Provides deterministic logic inversion with <7 ns delay and rail-to-rail output swing for clean edge transitions.

Use Value: Symmetrical output impedance ensures matched rise/fall times (<10% skew), critical for timing-critical enable/disable sequencing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar unbuffered inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AHC1G04DBVR	TI part in SOT-23-5 (same pinout); identical V_CC range and speed, but input tolerance limited to V_CC + 0.5 V	Not suitable for true mixed-voltage translation; requires matching V_CC to driven bus voltage	Select when system uses uniform 3.3 V or 5 V rails and cost is prioritized over voltage flexibility
74LVC1G04GW,125	Nexperia LVC variant in same SOT353-1 package; lower V_CC range (1.65–5.5 V), higher drive (±32 mA), but input tolerance only to V_CC + 0.3 V	Better for driving heavier capacitive loads, but cannot replace 74AHC1GU04GV in overvoltage translation roles	Select when driving >50 pF loads or needing faster edge rates at 3.3 V, with no overvoltage requirement

Compared with SN74AHC1G04DBVR and 74LVC1G04GW,125, the 74AHC1GU04GV,125 uniquely supports true overvoltage-tolerant input operation - enabling reliable level translation across disparate supply domains without external protection, making it irreplaceable in mixed-voltage oscillator and interface designs.

FAQ

What is the maximum input voltage the 74AHC1GU04GV,125 can tolerate?

The device accepts input voltages up to 5.5 V regardless of V_CC value - confirmed in Table 5 (Limiting Values) and Section 1 - enabling safe interfacing with 5 V buses even when powered from 2.0 V or 3.3 V. This overvoltage tolerance is intrinsic to the input structure and does not require external clamping.

Can the 74AHC1GU04GV,125 be used in crystal oscillator circuits?

Yes - Section 13 explicitly documents its use in Pierce oscillator configurations (Fig. 12), with recommended external components (R1, R2, C1, C2) for frequencies from 3 kHz to 600 kHz. Its unbuffered architecture, low input capacitance (10 pF), and stable gain profile make it suitable for low-jitter clock generation.

Is pin 1 on the 74AHC1GU04GV,125 marked with a dot or notch?

Per Table 2 and Figure 6.1, the marking code "AU4" is laser-etched on the top surface, and the pin 1 indicator is located in the lower-left corner below the marking - visible as a small bevel or dimple on the package edge, consistent with JEDEC-standard SC-74A (SOT753) orientation.

How does the 74AHC1GU04GV,125 differ from buffered inverters like 74AHC1G04?

Unlike buffered versions, the "U" in 74AHC1GU04 denotes unbuffered topology - resulting in lower propagation delay (7.0 ns vs ~8.5 ns) but higher sensitivity to load capacitance and reduced noise margin. It lacks internal stage isolation, making it preferred for oscillator feedback and analog biasing, not fanout distribution.
