STMicroelectronics 74LVXU04MTR

Overview

74LVXU04MTR from STMicroelectronics is a low-voltage CMOS hex inverter (single-stage) with 5V-tolerant inputs, operating from 2V to 3.6V supply, delivering 5.0ns typical propagation delay at 3.3V, ±4mA symmetrical output drive, and 2µA max quiescent current at 25°C - used in 3.3V logic interfacing, crystal oscillator biasing, and mixed-voltage level-shifting.

For engineers reviewing the 74LVXU04MTR datasheet, 74LVXU04MTR pinout, 74LVXU04MTR application, or 74LVXU04MTR equivalent, key selection criteria include 5V input tolerance, single-stage inverter topology for analog use, sub-10ns AC timing across temperature, ESD-hardened I/O (2kV HBM), and SO-14 package compatibility with legacy 74-series footprints.

Technical Context

This device implements six independent single-stage CMOS inverters fabricated in sub-micron C2MOS technology, enabling analog functionality such as Pierce oscillator configuration due to its unbuffered, high-gain inverter core. Its 5V-tolerant inputs accept 0–7V regardless of VCC, supporting robust 5V-to-3.3V signal translation without external resistors.

Power-down protection ensures safe input biasing during VCC=0, while symmetrical |IOH|=|IOL|≥4mA and balanced tPLH≈tPHL support clean digital waveform integrity. The 9pF power-dissipation capacitance (CPD) and 2µA ICC enable ultra-low static power in battery-critical systems.

FAQ

Can 74LVXU04MTR be used as a crystal oscillator amplifier?

Yes - its single-stage, unbuffered CMOS inverter architecture provides the high gain and phase inversion required for Pierce oscillator configurations. External bias resistor (typically 1–10MΩ) and load capacitors are needed; oscillation frequency depends on crystal parameters and layout parasitics.

What is the maximum input voltage when VCC = 0V?

Inputs tolerate 0V to 7V regardless of VCC state due to built-in power-down protection circuitry. This allows safe connection of powered 5V signals to the device even during system power-off or brownout conditions without risk of latch-up or damage.

Does 74LVXU04MTR support rail-to-rail output swing?

Yes - outputs swing from GND to VCC across the full operating temperature range (–55°C to +125°C) with guaranteed VOH ≥2.9V and VOL ≤0.1V at VCC=3.0V and IO=±50µA, meeting standard CMOS logic thresholds for reliable interfacing.

How does its 2µA ICC compare to similar hex inverters?

At 2µA max ICC (25°C), it consumes less than half the quiescent current of SN74LVC04A (4µA typ.) and one-fifth that of 74AHC04 (10µA typ.), making it optimal for always-on, energy-harvesting, or long-life battery applications where standby power dominates total energy budget.
