Product details
Overview
M74HCU04RM13TR from STMicroelectronics is a high-speed CMOS hex inverter (single-state) fabricated with silicon gate C2MOS technology, used for signal inversion and crystal oscillator circuits. It operates across 2V–6V supply, delivers 5ns typical propagation delay at 6V, supports ±4mA symmetrical output drive, and features 1µA max quiescent current at 25°C.
For engineers reviewing the M74HCU04RM13TR datasheet, M74HCU04RM13TR pinout, M74HCU04RM13TR application, or M74HCU04RM13TR equivalent, key selection criteria include VCC range compatibility, noise immunity (10% VCC min), balanced tPLH/tPHL delays, and TSSOP-14 package suitability for space-constrained digital logic designs.
Technical Context
The device implements six independent single-stage CMOS inverters in one monolithic IC, enabling direct use in Pierce-type crystal oscillator configurations without external feedback resistors. Its input protection circuitry includes diodes to GND and VCC for ESD and transient voltage resilience.
Designed for rail-to-rail operation, it maintains symmetrical output impedance (|IOH| = IOL ≥ 4mA) and balanced propagation delays (tPLH ≅ tPHL), ensuring minimal duty-cycle distortion in clock generation and waveform shaping applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCU04DR | Same AC/DC specs; SOIC-14 package (1.27mm pitch), higher thermal resistance (θJA = 120°C/W vs. 180°C/W) | Better suited for prototyping and through-hole rework; less optimal for high-density PCBs | Select when manual soldering or socket-based validation is required |
| 74LVC04PW,118 | Lower VCC range (1.65–5.5V); 3.5ns tPD at 3.3V; higher ICC (10µA typ.) | Optimized for 3.3V-only systems; not recommended for 5V or wide-VCC designs | Choose only if operating exclusively at 3.3V and sub-5ns delay is critical |
Compared with SN74HCU04DR and 74LVC04PW,118, the M74HCU04RM13TR uniquely supports full 2–6V operation with lowest quiescent current (1µA max) and TSSOP-14 footprint-making it optimal for compact, battery-sensitive, multi-rail digital timing applications.

FAQ
Can M74HCU04RM13TR be used in a Pierce oscillator without external resistors?
Yes. Its single-stage inverter architecture, combined with built-in input protection and rail-to-rail output swing, allows direct implementation in Pierce oscillator circuits using only a crystal and two load capacitors-no external feedback resistor is needed per STMicroelectronics application guidance.
What is the maximum capacitive load this device can drive reliably?
At VCC = 6V, the device maintains specified tPLH/tPHL and output voltage levels up to 50pF load capacitance, as validated in AC electrical characteristics testing. Driving >50pF may increase propagation delay and reduce edge rate but does not damage the part.
Does this part support 1.8V operation?
No. The absolute minimum recommended VCC is 2.0V per ST's Recommended Operating Conditions. At 1.8V, DC parameters such as VOH, VOL, and noise margins fall outside specification, and functionality is not guaranteed.
Is the TSSOP-14 package of M74HCU04RM13TR lead-free and RoHS compliant?
Yes. Per STMicroelectronics' packaging documentation, the M74HCU04RM13TR uses lead-free matte tin terminations and complies with EU RoHS Directive 2011/65/EU and JEDEC JS-001 ESD standards.
