STMicroelectronics 74LVX04MTR

Overview

74LVX04MTR from STMicroelectronics is a low-voltage CMOS hex inverter with 5V-tolerant inputs, operating from 2V to 3.6V supply, delivering 4.1ns typical propagation delay at 3.3V, ±4mA symmetrical output drive, and 2µA max quiescent current - used for level-shifting and signal inversion in 3.3V/5V mixed-voltage digital logic interfaces.

For engineers reviewing the 74LVX04MTR datasheet, 74LVX04MTR pinout, 74LVX04MTR application, or 74LVX04MTR equivalent, key selection criteria include 5V input tolerance, sub-5ns propagation delay at 3.3V, rail-to-rail output swing capability, ESD immunity (2kV HBM), and SO-14 tape-and-reel packaging for automated assembly.

Technical Context

This device implements six independent CMOS inverter gates using sub-micron C2MOS process technology, with three-stage buffered outputs to ensure high noise immunity and stable switching. Its input structure accepts 0–7V regardless of VCC, enabling robust interfacing between 5V legacy systems and 3.3V logic domains.

The internal design features power-down protection on all inputs, latch-up immunity enhancement, and symmetrical output impedance (|IOH| = IOL ≥ 4mA), ensuring matched rise/fall times (tPLH ≅ tPHL) and low dynamic noise (VOLP = 0.3V typ).

Key Specifications

FAQ

Is 74LVX04MTR pin-compatible with standard 74HC04 or 74LS04?

Yes - it follows the standard 14-pin SOIC layout and truth table of the 74xx04 family, with identical pin assignments (1A–6A inputs, 1Y–6Y outputs, GND, VCC). However, unlike 74LS04, it requires no pull-up resistors and operates down to 2V, while offering 5V-tolerant inputs absent in 74HC04.

Can 74LVX04MTR safely interface a 5V microcontroller GPIO to a 3.3V FPGA input?

Yes - its inputs tolerate 0–7V regardless of VCC, so a 5V GPIO can directly drive any input pin while VCC = 3.3V. The output swings rail-to-rail (0V/3.3V), matching FPGA I/O voltage requirements without risk of overvoltage damage.

What is the maximum capacitive load this device can drive while maintaining 4.1ns propagation delay?

The 4.1ns typical tPD is specified at CL = 15pF. At CL = 50pF, tPD increases to 6.6ns (typ) at VCC = 3.3V. For designs requiring ≤5ns delay, total load (including trace and input capacitance) should be kept below ~20pF.

Does 74LVX04MTR require external decoupling capacitors?

Yes - STMicroelectronics recommends a 100nF ceramic capacitor placed as close as possible to the VCC pin (Pin 14) and GND (Pin 7) to suppress supply noise and maintain stable switching performance, especially under fast transient loads across all six gates.
