### **Descriptions:**  
The SN54HC259J is a high-speed CMOS 8-bit addressable latch designed for military and industrial applications. It features a common reset input and can store data in any one of the eight latches based on the address inputs.  

### **Features:**  
- **8-Bit Addressable Latch:** Stores data in a selected latch.  
- **Common Reset:** Clears all latches simultaneously.  
- **High-Speed Operation:** Optimized for fast data storage.  
- **Wide Operating Voltage:** Supports 2V to 6V.  
- **Low Power Consumption:** CMOS technology ensures low power usage.  
- **Military Temperature Range:** Suitable for harsh environments.  
- **Schmitt Trigger Inputs:** Improves noise immunity.  

This device is commonly used in memory addressing, data routing, and control applications.

Application Scenarios & Design Considerations

8-Bit Addressable Latches

Alternative Part Number

  • CD74HC259E --: Same 8-bit addressable latch function in a different TI series (CD74HC), directly pin-compatible in most designs.
  • MC74HC259N --: Equivalent 8-bit addressable latch from another vendor with the same HC logic family and DIP package.
  • 74HC259N --: Standard 74HC259 addressable latch offering the same function and pinout, suitable as a drop-in replacement.
  • MM74HC259N --: Another 74HC-series 8-bit addressable latch with matching logic function and DIP pinout, usable as a drop-in functional substitute.
