Description and Introduction

Quad 2-Input OR Gate The SN74LS32MEL is a quad 2-input positive-OR gate from Texas Instruments.  

### **Manufacturer Specifications:**  
- **Logic Type:** OR Gate  
- **Number of Inputs:** 2  
- **Number of Gates:** 4  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** -55°C to 125°C  
- **Package Type:** SOIC (Small Outline Integrated Circuit)  
- **Mounting Type:** Surface Mount  
- **Propagation Delay:** Typically 15ns at 5V  
- **Output Current:** 8mA (High), 16mA (Low)  

### **Descriptions:**  
The SN74LS32MEL is part of the 74LS logic family, providing four independent 2-input OR gates in a single package. It is designed for high-speed logic operations with low power consumption.  

### **Features:**  
- **Low Power Consumption:** Typical power dissipation of 10mW per gate  
- **TTL-Compatible Inputs:** Works with standard TTL logic levels  
- **High-Speed Operation:** Fast switching for logic applications  
- **Wide Operating Voltage Range:** Supports standard 5V logic systems  
- **Surface-Mount Package:** Compact SOIC form factor for PCB integration  

This information is based solely on the manufacturer's datasheet.

Application Scenarios & Design Considerations

Quad 2-Input OR Gate

Alternative Part Number

  • MC74LS32DR2G --: Quad 2-input OR gate in the same LS logic family with identical pinout and function, widely available and directly drop-in compatible.
  • DM74LS32N --: Equivalent 74LS32 quad OR gate from a different series prefix, electrically and functionally interchangeable in most designs.
  • SN74HC32DR --: CMOS HC-family quad OR gate with same logic function and pinout; suitable when lower power is acceptable, though input thresholds differ from LS.
  • SN74LS32N --: Same 74LS32 quad 2-input OR gate function in a standard DIP package, widely available and pin-compatible for through-hole designs.
