Description and Introduction

HEX INVERTER The SN74LS04D is a hex inverter IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Inverter  
- **Number of Circuits:** 6 (Hex)  
- **Supply Voltage Range (VCC):** 4.75V to 5.25V  
- **High-Level Output Current (IOH):** -0.4mA  
- **Low-Level Output Current (IOL):** 8mA  
- **Propagation Delay Time (tpd):** 15ns (Max)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** SOIC-14  

### **Description:**  
The SN74LS04D is a member of the 74LS logic family, featuring six independent inverters. It is designed for general-purpose logic applications and operates with TTL (Transistor-Transistor Logic) levels.  

### **Features:**  
- **Hex Inverter Gates:** Contains six independent NOT gates.  
- **TTL-Compatible Inputs:** Works with standard TTL logic levels.  
- **Low Power Consumption:** Typical power dissipation of 10mW per gate.  
- **Wide Operating Voltage Range:** Supports standard 5V operation.  
- **High Noise Immunity:** Improved noise resistance compared to earlier TTL families.  

This IC is commonly used in digital circuits for signal inversion, buffering, and logic level conversion.

Application Scenarios & Design Considerations

HEX INVERTER

Alternative Part Number

  • MC74HC04ADR2G --: Hex inverter in SOIC-14 with similar function; HC family offers lower power and is a common drop-in for LS logic in many designs.
  • CD74HC04M --: Same manufacturer hex inverter in SOIC-14, HC series provides compatible pinout with reduced power consumption versus LS.
  • 74HCT04D --: Hex inverter in SOIC-14 with TTL-compatible inputs, suitable direct replacement for LS04 in 5V systems.
  • DM74LS04M --: Same 74LS04 hex inverter function in SOIC-14 package, pin-compatible and widely available from a different manufacturer.
  • MC74LS04DR2 --: Direct functional equivalent hex inverter in SOIC-14, different series prefix and manufacturer, good availability.
  • SN74LS04DR --: Same logic function and SOIC-14 footprint from the original design lineage, though naming differs from the source part.
