### **Description:**  
The M74HC32B1 is a high-speed CMOS logic device containing four independent 2-input OR gates. It is designed for general-purpose logic applications and operates over a wide voltage range, making it suitable for battery-powered and industrial applications.  

### **Features:**  
- **Quad 2-input OR gates**  
- **Compatible with TTL levels**  
- **Wide operating voltage range (2V to 6V)**  
- **Balanced propagation delays**  
- **High noise immunity**  
- **Low power consumption**  
- **Pb-free and RoHS compliant**  

This IC is commonly used in digital logic circuits, signal processing, and control systems.

Application Scenarios & Design Considerations

QUAD 2-INPUT OR GATE

Alternative Part Number

  • SN74HC32N --: Pin-compatible quad 2-input OR gate in the same HC logic family with equivalent electrical characteristics, widely available from a major supplier.
  • CD74HC32E --: Direct functional equivalent quad 2-input OR gate in DIP package, same HC speed and voltage range, good second-source option.
  • MC74HC32ANG --: Quad 2-input OR gate in HC family with matching pinout and logic levels, suitable drop-in replacement in most designs.
