Nexperia USA Inc. 74LVC3GU04DP,125

Overview

74LVC3GU04DP from Nexperia is a triple unbuffered CMOS inverter IC operating from 1.65 V to 5.5 V, featuring ±24 mA output drive at 3.0 V, overvoltage-tolerant inputs up to 5.5 V, and guaranteed operation from −40 °C to +125 °C in TSSOP8 (SOT505-2) package. It enables level-shifting and signal inversion in mixed-voltage digital systems such as industrial I/O interfaces and low-power microcontroller peripheral conditioning.

For engineers reviewing the 74LVC3GU04DP datasheet, 74LVC3GU04DP pinout, 74LVC3GU04DP application, or 74LVC3GU04DP equivalent, key selection criteria include input voltage tolerance across supply rails, propagation delay consistency over temperature, output drive capability at 3.0 V, and compatibility with 3.3 V/5 V mixed-signal logic domains.

Technical Context

This device implements three independent unbuffered inverter stages using standard CMOS topology-no internal buffering between input and output-resulting in minimal propagation delay (as low as 0.3 ns at 5 V) and high noise immunity. Each gate exhibits rail-to-rail output swing and supports direct interfacing with both 3.3 V and 5 V logic families due to 5.5 V tolerant inputs.

The architecture enables use in oscillator configurations (e.g., Pierce crystal driver) and linear amplifier applications when biased externally, leveraging its high transconductance and low input capacitance (5 pF). It is not designed for analog switching or power control but strictly for digital signal inversion and waveform shaping.

FAQ

Can the 74LVC3GU04DP drive a 50 pF load at 10 MHz without signal degradation?

Yes. With typical propagation delay of 2.3 ns and output drive of ±24 mA at 3.0 V, it maintains clean edges into 50 pF loads up to 20 MHz. Measured tpd variation remains under ±0.3 ns across temperature, and dynamic power dissipation (CPD = 7 pF) ensures minimal jitter accumulation in clock distribution paths.

Is the 74LVC3GU04DP pin-compatible with older 74HC or 74HCT triple inverters?

No. While functional equivalence exists, pinout differs: 74LVC3GU04DP uses TSSOP8 (SOT505-2) with inputs on pins 1/3/6 and outputs on 7/5/2, whereas 74HC3G04 variants often use SC-70 or different TSSOP mappings. Direct replacement requires PCB redesign or adapter.

Does the 74LVC3GU04DP support partial power-down operation with I/Os active while VCC = 0 V?

No. The device lacks Ioff protection. When VCC = 0 V, inputs and outputs must be held at GND or ≤0.5 V to prevent back-powering or latch-up. For hot-swap or partial-power scenarios, consider LVC variants with explicit Ioff specification (e.g., 74LVC1G125).

What is the maximum recommended trace length for driving a 3.3 V microcontroller input with 74LVC3GU04DP at 50 MHz?

For 50 MHz operation, keep trace lengths ≤4 cm with controlled 50 Ω impedance and local 100 nF decoupling at the inverter's VCC pin. At that frequency, measured tpd variation stays within 0.2 ns, and output rise/fall times (≤2.5 ns) ensure adequate slew rate margin even with 10 pF net capacitance.
