Description and Introduction

HEX INVERTER (SINGLE STAGE) The M74HCU04 is a high-speed CMOS hex inverter manufactured by SGS-THOMSON (now STMicroelectronics). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Technology:** High-Speed CMOS  
- **Supply Voltage Range (VCC):** 2V to 6V  
- **Input Voltage Range (VI):** 0V to VCC  
- **Operating Temperature Range:** -40°C to +85°C  
- **Propagation Delay (typical):** 8 ns at VCC = 4.5V, CL = 15 pF  
- **Input Current (Max):** ±1 µA  
- **Output Current (Max):** ±25 mA  
- **Power Dissipation (Max):** 500 mW  

### **Descriptions:**
- The M74HCU04 is a hex inverter, meaning it contains six independent inverters in a single package.  
- It is unbuffered, providing a direct signal inversion without additional buffering stages.  
- Designed for general-purpose logic applications where signal inversion is required.  
- Compatible with TTL levels when operated at 4.5V to 5.5V.  

### **Features:**
- **High Noise Immunity:** Typical CMOS noise margin of 30% of VCC.  
- **Low Power Consumption:** Quiescent current of 1 µA (max) at 5V.  
- **Balanced Propagation Delays:** Ensures stable performance in high-speed applications.  
- **Wide Operating Voltage Range:** Supports 2V to 6V operation.  
- **Unbuffered Outputs:** Provides faster response compared to buffered inverters.  
- **Pin-Compatible with 74LS04:** Allows for easy replacement in existing designs.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

HEX INVERTER (SINGLE STAGE)

Alternative Part Number

  • CD74HCU04E --: Pin-compatible hex unbuffered inverter from the 74HCU series with equivalent electrical characteristics and widely available.
  • MC74HCU04ADG --: Same 74HCU04 unbuffered inverter function in SOIC package, direct functional replacement with similar drive and speed.
  • SN74HCU04N --: Standard 74HCU04 hex unbuffered inverter, same logic family and pinout, suitable drop-in substitute.
  • MC74HCU04AN --: Equivalent HCU-series hex unbuffered inverter from another major vendor, same electrical characteristics and DIP/SOIC pinout.
