Product details

Overview

74LVC3GU04GF,115 from Nexperia is a triple unbuffered CMOS inverter IC operating from 1.65 V to 5.5 V supply, featuring overvoltage-tolerant inputs up to 5.5 V, ±24 mA output drive at 3.0 V, and guaranteed operation from –40 °C to +125 °C. It enables level-shifting and signal inversion in mixed-voltage digital logic interfaces, such as I²C bus conditioning or clock signal cleanup in industrial microcontroller peripherals.

For engineers reviewing the 74LVC3GU04GF,115 datasheet, 74LVC3GU04GF,115 pinout, 74LVC3GU04GF,115 application, or 74LVC3GU04GF,115 equivalent, key selection criteria include input voltage tolerance across 3.3 V/5 V domains, propagation delay under 3.8 ns at 5 V, low ICC standby current (≤4 μA), and compatibility with XSON8 (SOT1089) footprint for space-constrained PCB layouts.

Technical Context

This device implements three independent unbuffered inverter stages using standard CMOS topology, with no internal buffering-enabling direct use in crystal oscillator feedback loops (per Fig. 9) and linear amplifier configurations (per Fig. 8). Each gate exhibits rail-to-rail output swing and symmetrical input thresholds defined as VIH ≥ 0.8×VCC and VIL ≤ 0.2×VCC over the full temperature range.

Its unbuffered architecture results in lower propagation delay (as low as 0.3 ns typical at 5 V) but higher sensitivity to capacitive loading compared to buffered inverters. Input clamping diodes support overvoltage tolerance, while ESD protection meets HBM >2000 V and CDM >1000 V per JEDEC JS-001/JS-002.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.65 V to 5.5 V - supports direct interface between 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters.
Input Voltage Tolerance	Up to 5.5 V - allows safe connection to 5 V outputs even when powered from 3.3 V or lower supplies.
Output Drive Strength	±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC inputs or small capacitive loads (e.g., 30–50 pF) without external buffers.
Propagation Delay	≤3.8 ns max at VCC = 4.5–5.5 V - enables reliable operation in high-speed control paths up to ~100 MHz toggle rate.
Operating Temperature	–40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and extended-range power supply monitoring circuits.
Static Supply Current	≤4 μA at VCC = 1.65–5.5 V - minimizes quiescent power in battery-backed or always-on subsystems.
Input Capacitance	5 pF typical - limits high-frequency loading on upstream drivers and preserves signal integrity in dense routing.

Pinout & Package

The 74LVC3GU04GF,115 is packaged in XSON8 (SOT1089), an 8-terminal leadless plastic package measuring 1.0 × 1.45 × 0.35 mm, optimized for automated placement and high-density PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
1	Input A1	First inverter input; accepts 0–5.5 V signals regardless of VCC setting.
2	Output Y1	Inverted output of A1; drives downstream logic or passive loads with rail-to-rail swing.
3	Input A2	Second inverter input; electrically isolated from A1/Y1 and A3/Y3.
4	GND	Digital ground reference; must be low-impedance and decoupled near VCC pin.
5	Output Y2	Inverted output of A2; shares same VCC/GND rails but operates independently.
6	Input A3	Third inverter input; supports identical voltage and timing specs as A1/A2.
7	Output Y3	Inverted output of A3; usable for parallel signal inversion or oscillator feedback.
8	VCC	Positive supply rail; requires local 100 nF ceramic decoupling capacitor.

Key Features

Feature	Design Value
Triple unbuffered inverter topology	Enables crystal oscillator implementation (Fig. 9) and linear amplifier biasing (Fig. 8) without added propagation delay from internal buffers.
Overvoltage-tolerant inputs	Accepts 5.5 V inputs while powered from as low as 1.65 V - eliminates need for external clamping or level translation in mixed-supply systems.
High noise immunity	Guaranteed VIH/VIL margins (≥0.8×VCC / ≤0.2×VCC) ensure robust switching in electrically noisy industrial environments.
Low dynamic power dissipation	CPD = 7 pF at 3.3 V - reduces switching power in high-frequency clock distribution or data path inversion.
Latch-up immunity	Exceeds 250 mA per JESD78 - prevents destructive latch-up during transient overvoltage events in motor control or relay driver interfaces.

IC Role / Device Role / Timing Role: Signal polarity correction and voltage-level adaptation between 5 V sensor stage and 3.3 V host MCU.

Use Value: Eliminates need for discrete MOSFET level shifters; maintains <3.8 ns propagation delay for real-time response in closed-loop thermal control.

Use Scenario: Driving I²C SCL/SDA lines with enhanced rise time in multi-master systems where bus capacitance exceeds 400 pF.

IC Role / Device Role / Timing Role: Active pull-up inverter replacing passive resistors to reduce RC time constant and meet fast-mode (400 kHz) timing budgets.

Use Value: Enables reliable 400 kHz I²C operation with 3.3 V VCC and 5 V tolerant inputs - compatible with legacy 5 V peripherals on same bus.

Crystal Oscillator Buffer

Microcontroller Reset Signal Inversion

Use Scenario: Constructing a Pierce oscillator using a 32.768 kHz tuning-fork crystal and two inverter stages (one as amplifier, one as buffer).

IC Role / Device Role / Timing Role: Unbuffered inverter configured as linear amplifier (Fig. 8) plus inverter stage for 180° phase shift in oscillator loop.

Use Value: Achieves stable oscillation at 32.768 kHz with <1.5 Vpp output swing and <10 ppm frequency drift over –40 °C to +85 °C.

Use Scenario: Inverting active-low reset signal from a supervisor IC (e.g., MAX809) to match active-high reset requirement of an ARM Cortex-M0+ MCU.

IC Role / Device Role / Timing Role: Logic-level inversion with sub-4 ns delay to preserve reset assertion timing margin in power-up sequencing.

Use Value: Guarantees <10 ns total reset path delay from supervisor output to MCU reset pin, meeting 15 ns setup requirement for 64 MHz core clocks.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC3G04DCUR	Same logic function and electrical specs; packaged in VSSOP8 (SOT765-1), 2.3 mm body width.	Requires larger PCB area than XSON8; better thermal dissipation at sustained 24 mA loads.	Select when board layout allows 2.3 mm width and thermal management is prioritized over miniaturization.
74LVC3G04GM,115	Discontinued per Rev. 14 datasheet; previously offered in XQFN8 (SOT902-2) with 1.3 × 1.3 mm footprint.	No longer manufactured; not recommended for new designs due to obsolescence risk.	Avoid for production; verify lifetime buy availability if supporting legacy builds only.

Compared with SN74LVC3G04DCUR and discontinued 74LVC3G04GM,115, the 74LVC3GU04GF,115 offers the smallest footprint (1.0 × 1.45 mm) and highest density integration for space-constrained IoT edge nodes, while maintaining identical timing, drive, and voltage specs - making it optimal for next-generation wearables and compact industrial sensors.

FAQ

Is the 74LVC3GU04GF,115 pin-compatible with other 74LVC3G-series triple gates?

Yes - it shares identical XSON8 (SOT1089) pinout with all 74LVC3Gxxx variants in the same package, including 74LVC3G14 (Schmitt-trigger inverter) and 74LVC3G74 (dual D-type flip-flop). Pin 1 is input A1, pin 2 is output Y1, pin 3 is input A2, pin 4 is GND, pin 5 is output Y2, pin 6 is input A3, pin 7 is output Y3, and pin 8 is VCC. This allows drop-in replacement for functional evaluation.

Can the 74LVC3GU04GF,115 be used as a linear amplifier?

Yes - per Figure 8 in the datasheet, one inverter stage can be biased with R1/R2 feedback to operate in its linear region, delivering a typical open-loop gain of 20 and unity-gain bandwidth of 5 MHz. This configuration requires 1 µF AC-coupling at input and output, and is validated for VCC = 3.3 V with ZL > 10 kΩ load impedance.

What is the maximum capacitive load this device can drive while maintaining timing specs?

The datasheet specifies dynamic characteristics with 30 pF (for VCC ≤ 2.7 V) and 50 pF (for VCC ≥ 3.0 V) loads. Propagation delay remains within spec up to 50 pF; beyond that, tpd increases linearly - e.g., at 100 pF and VCC = 3.3 V, measured tpd rises to ~6.2 ns. For >50 pF loads, add series resistance to limit slew rate and prevent ringing.

Does the 74LVC3GU04GF,115 support partial power-down operation?

No - the device lacks Ioff (power-off protection) specification. When VCC = 0 V, inputs must be held at GND or VCC to avoid forward-biasing internal clamp diodes. Per Section 8, VI must remain within –0.5 V to +6.5 V regardless of VCC state; floating inputs during power-down may cause excessive ICC or latch-up.
