Description and Introduction

9-bit odd/even parity generators / checkers The SN74LS280J is a 9-bit parity generator/checker manufactured by Motorola (MOT).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Function:** 9-bit Parity Generator/Checker  
- **Operating Voltage:** 4.75V to 5.25V  
- **Propagation Delay:** 15ns (typical)  
- **Power Dissipation:** 32mW (typical)  
- **Package Type:** 14-pin PDIP (Plastic Dual In-line Package)  
- **Operating Temperature Range:** 0°C to 70°C  

### **Descriptions:**  
The SN74LS280J is designed to generate or check parity for 9-bit data words. It can be used in error detection and correction systems, ensuring data integrity in digital communications and memory systems.  

### **Features:**  
- **Odd/Even Parity Selection:** Can generate or check both odd and even parity.  
- **High-Speed Operation:** Suitable for fast digital systems.  
- **Low Power Consumption:** Optimized for power efficiency.  
- **Wide Operating Voltage Range:** Compatible with standard TTL logic levels.  
- **Standard 14-Pin DIP Package:** Easy to integrate into existing designs.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

9-bit odd/even parity generators / checkers

Alternative Part Number

  • MC74LS280N --: Same 9-bit odd/even parity generator function in the LS logic family, widely available and pin-compatible in DIP package.
  • DM74LS280N --: Direct functional equivalent parity generator/checker with LS TTL characteristics, suitable drop-in replacement in DIP-14.
  • CD74HC280E --: CMOS parity generator with similar function; check supply voltage and drive levels, but works as a functional substitute in many designs.
