Product details
Overview
74AHC3G04DC,125 from Nexperia is a triple CMOS inverter IC with overvoltage-tolerant inputs (up to 5.5 V), operating across 2.0–5.5 V supply range, specified for -40 °C to +125 °C, and housed in an 8-pin VSSOP package (SOT765-1). It serves as a level-translating logic buffer in mixed-voltage digital subsystems such as I²C bus interface conditioning, microcontroller GPIO signal inversion, and clock domain isolation.
For engineers reviewing the 74AHC3G04DC,125 datasheet, 74AHC3G04DC,125 pinout, 74AHC3G04DC,125 application, or 74AHC3G04DC,125 equivalent, this device is selected for low-power, rail-to-rail compatible inversion in space-constrained industrial control modules, sensor interface boards, and portable embedded systems requiring robust noise immunity and wide-VCC operation.
Technical Context
This device implements three independent CMOS inverter gates in a single monolithic die, each with symmetrical output drive capability (±8 mA at VCC = 4.5 V) and balanced propagation delays (3.1–7.0 ns typical, depending on VCC and load). Its overvoltage-tolerant inputs enable direct interfacing between 3.3 V logic domains and 5 V peripherals without external level shifters.
The AHC family uses CMOS input thresholds (VIH ≥ 3.85 V @ VCC = 5.5 V; VIL ≤ 1.65 V), ensuring compatibility with both 3.3 V and 5 V logic families while maintaining low static current (ICC ≤ 40 μA at VCC = 5.5 V, -40 °C to +125 °C) and high noise margins (>1.5 V at VCC = 5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - supports dual-rail operation in mixed-voltage systems without external regulators. |
| Input Voltage Tolerance | Up to 5.5 V - enables safe interfacing with higher-voltage signals even when VCC = 2.0 V. |
| Propagation Delay | 3.1 ns (typ) @ VCC = 5.0 V, CL = 15 pF - ensures timing predictability in high-speed digital control paths. |
| Output Drive Strength | ±8.0 mA @ VCC = 4.5 V - sufficient to drive standard TTL/CMOS loads and small capacitive buses. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive auxiliary modules and industrial motor drives. |
| Power Dissipation Capacitance | 9 pF per gate - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) in battery-sensitive designs. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - reduces need for external ESD 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; lead pitch 0.5 mm; thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input A1 | First inverter input; overvoltage tolerant up to 5.5 V regardless of VCC. |
| 2 | Output Y3 | Third inverter output; actively driven HIGH/LOW with symmetrical impedance (~30 Ω typical). |
| 3 | Input A2 | Second inverter input; electrically isolated from other inputs; supports independent signal routing. |
| 4 | GND | Dedicated ground reference; must be low-impedance connection to minimize switching noise coupling. |
| 5 | Output Y2 | Second inverter output; matches Y1/Y3 timing and drive strength within ±10% variation. |
| 6 | Input A3 | Third inverter input; shares same VIH/VIL thresholds and leakage (<0.1 μA) as A1/A2. |
| 7 | Output Y1 | First inverter output; pin 7 is standard output location per JEDEC logic symbol convention. |
| 8 | VCC | Single positive supply rail; decoupling capacitor (100 nF ceramic) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 2.0–5.5 V operation eliminates need for separate voltage translators in multi-rail PCBs. |
| Overvoltage-Tolerant Inputs | Inputs withstand 5.5 V regardless of VCC setting - enables use as bidirectional level shifter in I²C pull-up domains. |
| Symmetrical Output Impedance | Matched HIGH/LOW drive strength (±8 mA) ensures consistent rise/fall times and reduced signal distortion. |
| High Noise Immunity | VIH–VIL margin >1.5 V at VCC = 5 V - suppresses false triggering in electrically noisy PLC backplanes. |
| Latch-Up Immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during transient overvoltage events. |
Applications
| Industrial Sensor Interface | I²C Bus Signal Conditioning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT3G04DC,125 | TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max); narrower VCC range (4.5–5.5 V). | Required only when interfacing legacy 5 V TTL logic; unsuitable for 3.3 V-only systems. | Select when existing design uses strict TTL signaling and no mixed-voltage translation is needed. |
| SN74LVC3G04DCUR | Lower VCC range (1.65–5.5 V); higher drive (±24 mA); smaller X2SON8 package (1.5 × 1.0 mm). | Better suited for ultra-portable devices with tight space constraints and higher fanout requirements. | Prefer for new designs targeting <2 mm² footprint and >16 mA output drive per gate. |
Compared with 74AHCT3G04DC,125, the AHC version offers broader supply flexibility and true mixed-voltage translation; compared with SN74LVC3G04DCUR, it trades higher drive and smaller size for superior latch-up immunity (100 mA vs. 250 mA JESD78) and extended high-temperature stability.

FAQ
Can 74AHC3G04DC,125 operate with VCC = 2.5 V while accepting 5 V inputs?
Yes. The device's overvoltage-tolerant inputs allow VI up to 5.5 V independent of VCC, enabling safe 5 V signal reception at VCC = 2.5 V. Static parameters (VIH/VIL) scale with VCC, but input clamping diodes prevent damage, and functional operation is guaranteed per Table 6 and Table 7.
What is the maximum capacitive load this device can drive reliably at 5 V?
At VCC = 5.0 V, the device maintains specified tpd ≤ 7.0 ns (max) up to CL = 50 pF per output, as verified in Table 8. For loads exceeding 50 pF, propagation delay increases linearly; derating is recommended above 75 pF to avoid timing violations in synchronous systems.
Does this part support hot insertion or live swapping in powered systems?
No. While inputs tolerate overvoltage, the device lacks hot-swap protection circuitry (e.g., power-on reset, I²C bus arbitration). Applying VCC after signal inputs may cause undefined states or excessive ICC; always power VCC before applying input signals in live systems.
How does the 74AHC3G04DC,125 differ from the 74AHC3G04DP variant?
Both share identical electrical specifications and logic function, but differ only in package: DC uses VSSOP8 (SOT765-1, 2.3 mm body width), while DP uses TSSOP8 (SOT505-2, 3.0 mm body width). Thermal resistance differs (RθJA = 190 K/W for DC vs. 170 K/W for DP), affecting power handling in high-density layouts.
