Product details
Overview
74LVC3GU04GD,125 from Nexperia is a triple unbuffered CMOS inverter IC operating from 1.65 V to 5.5 V supply, delivering ±24 mA output drive at 3.0 V, with overvoltage-tolerant inputs up to 5.5 V and specified for -40 °C to +125 °C operation. It enables level-shifting and signal inversion in mixed-voltage digital logic interfaces such as I²C pull-up networks, clock buffering, and reset signal conditioning.
For engineers reviewing the 74LVC3GU04GD,125 datasheet, 74LVC3GU04GD,125 pinout, 74LVC3GU04GD,125 application, or 74LVC3GU04GD,125 equivalent, key selection criteria include input overvoltage tolerance, propagation delay under 3.8 ns (VCC = 4.5–5.5 V), output drive capability at low VCC, thermal derating behavior per package, and compatibility with 1.8 V/3.3 V/5 V logic families.
Technical Context
This device implements three independent unbuffered inverter stages using standard CMOS topology-no internal feedback or Schmitt-trigger hysteresis. Each gate exhibits symmetrical input/output characteristics, with VIH/VIL thresholds defined as fractions of VCC (e.g., VIH ≥ 0.8 × VCC at -40 °C to +125 °C) and VOL ≤ 0.80 V at 24 mA sink current (VCC = 3.0 V).
Propagation delay (tpd) is measured between input and output crossing 0.5 × VCC (or fixed 1.5 V at 2.7 V), with typical values ranging from 1.7 ns (VCC = 5.0 V) to 6.3 ns (VCC = 1.8 V, -40 °C to +125 °C). Power dissipation capacitance (CPD) is 7 pF, enabling accurate dynamic power estimation across frequency and load conditions.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| Triple unbuffered inverter topology | Enables compact implementation of three independent logic inversions without added propagation delay from buffer stages. |
| Wide VCC range (1.65–5.5 V) | Eliminates need for separate voltage translators in mixed-supply systems such as FPGA I/O banks interfacing with microcontrollers. |
| Overvoltage-tolerant inputs | Permits direct connection of 5 V signals to 3.3 V or 1.8 V domains without external clamping diodes or resistors. |
| High noise immunity | Guaranteed by wide input threshold margins (VIH ≥ 0.8×VCC, VIL ≤ 0.2×VCC at full temp range), reducing susceptibility to crosstalk and ground bounce. |
| Latch-up immunity >250 mA | Ensures robustness against transient current surges during hot-plug or ESD events, meeting JEDEC JESD78 requirements. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unbuffered inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G04DCUR | TI part in VSSOP8 (SOT765-1); identical electrical specs but different pinout (1A/2A/3A on pins 1/3/6 vs. 1A/2A/3A on pins 2/3/1 in 74LVC3GU04GD). | Same functional use, but requires PCB layout revision due to non-identical pin mapping and package footprint. | Select when TI sourcing preference exists and board redesign is acceptable; verify pin compatibility before substitution. |
| 74LVC1G04GW,125 | Nexperia single-gate variant in SOT353 (5-pin); lacks two additional inverters and has different pin assignment (no GND/VCC symmetry). | Only suitable if only one inverter is needed; cannot replace triple function without adding two more devices and increasing board area. | Choose only for minimal-gate-count applications where space permits multiple single-gate packages and routing overhead is acceptable. |
Compared with SN74LVC3G04DCUR and 74LVC1G04GW,125, the 74LVC3GU04GD,125 offers optimal integration density and pinout consistency across Nexperia's LVC family, making it preferred for new designs requiring three matched inverters in ultra-compact XSON8 packaging.

FAQ
Is the 74LVC3GU04GD,125 pin-compatible with other 74LVC3Gxxx variants in XSON8 packages?
No - pin assignments differ across functions. For example, 74LVC3GU04GD places 1A at pin 1, 2A at pin 2, and 3A at pin 3, whereas 74LVC3G74GW uses pin 1 for CLK and pin 2 for D. Always verify pin mapping per datasheet before PCB layout or substitution.
Can this device operate reliably at 1.65 V supply while driving 24 mA loads?
No - output drive capability degrades at minimum VCC. At VCC = 1.65 V, the device guarantees only ±4 mA output current (per datasheet Table 7). Full ±24 mA performance requires VCC ≥ 3.0 V; use appropriate VCC scaling for target load conditions.
What is the significance of "unbuffered" in the device description?
Unbuffered means each inverter consists of a single CMOS inverter stage without additional gain or isolation buffers. This yields lower propagation delay and reduced power consumption but also lower noise immunity and less drive strength than buffered equivalents like 74LVC3G14 (Schmitt-trigger) or 74LVC3G07 (open-drain).
Does the 74LVC3GU04GD,125 support hot-swap or live-insertion applications?
It provides overvoltage-tolerant inputs and latch-up immunity >250 mA, which improve robustness during hot-swap events. However, it lacks explicit hot-swap control features (e.g., slew-rate limiting, undervoltage lockout). External current-limiting resistors and soft-start circuitry are recommended for reliable live-insertion use.
