Description and Introduction

8-Bit Adder Latch The SN74LS259N is a 8-bit addressable latch manufactured by **MOT (Motorola)**.  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Logic Type:** Addressable Latch  
- **Number of Bits:** 8  
- **Output Type:** Standard  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 16-Pin DIP (Dual In-line Package)  
- **Propagation Delay:** Typically 25ns  
- **Current Consumption (ICC):** 12mA (max)  

### **Descriptions & Features:**  
- **8-bit parallel-out storage register** with addressable latch functionality.  
- **Common Clear input** for resetting all latches.  
- **3-to-8 decoder** for selecting individual latches.  
- **Non-inverting outputs** for direct logic interfacing.  
- **Schottky-clamped** for improved speed and noise immunity.  
- **TTL-compatible** inputs and outputs.  
- **Wide operating voltage range** for reliable 5V operation.  

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

Application Scenarios & Design Considerations

8-Bit Adder Latch

Alternative Part Number

  • DM74LS259N --: Same 8-bit addressable latch function in a DIP-16 package with LS TTL logic levels, a direct functional equivalent from a different series prefix.
  • CD74HCT259E --: HCT CMOS version of the 8-bit addressable latch, pin-compatible DIP-16 with TTL-compatible inputs, suitable drop-in replacement.
  • MC74HC259N --: HC CMOS 8-bit addressable latch in DIP-16, pin-compatible and functionally equivalent, though input thresholds are CMOS rather than TTL.
