Description and Introduction

Dual 5-input positive-NOR gates The SN74S260D is a dual 5-input positive-NOR gate manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** NOR Gate  
- **Number of Inputs:** 5 per gate (dual gate, 2 gates in one package)  
- **Output Type:** Standard  
- **Supply Voltage Range:** 4.75V to 5.25V (TTL compatible)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** SOIC (Small Outline Integrated Circuit)  
- **Mounting Type:** Surface Mount  
- **Propagation Delay:** Typically 7.5ns (varies with conditions)  
- **Power Dissipation:** Typically 45mW per gate  

### **Description:**  
The SN74S260D is part of TI's 74S series, which features Schottky-clamped transistors for improved speed. It provides two independent 5-input NOR gates in a single package, making it useful for high-speed logic applications.  

### **Features:**  
- High-speed operation (Schottky TTL)  
- Dual 5-input NOR gates in one IC  
- Standard TTL voltage levels  
- Low power consumption for its speed class  
- Surface-mount package (SOIC) for compact designs  

For detailed electrical characteristics and timing diagrams, refer to the official TI datasheet.

Application Scenarios & Design Considerations

Dual 5-input positive-NOR gates

Alternative Part Number

  • MC10H104L --: Dual 4-input NOR gate in a different series (MECL 10H) with similar logic function and DIP-compatible package, usable as a functional substitute in many designs.
  • 74F260D --: Dual 4-input NOR gate from the 74F family with comparable speed and drive, pin-compatible with the SN74S260D in the same DIP package.
  • CD74ACT260E --: Dual 4-input NOR gate from the ACT CMOS family offering lower power and similar logic function, though speed and drive differ slightly from the original Schottky device.
  • MC10102L --: Dual 4-input NOR gate in the same logic function family, usable as a functional substitute where ECL-level compatibility is acceptable.
  • CD4001BE --: Quad 2-input NOR gate that can implement equivalent NOR logic with a different series and pinout, suitable for redesigns.
  • 74HC02D --: Quad 2-input NOR gate in SOIC package offering a modern CMOS alternative for NOR logic functions with lower power consumption.
