Description and Introduction

9-Bit Parity Generators/Checkers The SN74AS280NSR is a 9-bit odd/even parity generator/checker manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Part Number:** SN74AS280NSR  
- **Type:** 9-bit Parity Generator/Checker  
- **Logic Family:** AS (Advanced Schottky)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** SOIC (Small Outline Integrated Circuit)  
- **Pin Count:** 14  
- **Input Type:** TTL-Compatible  
- **Output Type:** TTL-Compatible  
- **Propagation Delay:** Typically 7.5 ns  
- **Power Dissipation:** Low power consumption for AS family  

### **Descriptions:**  
The SN74AS280NSR is designed to generate or check parity for 9-bit data words. It provides both even and odd parity outputs, making it useful for error detection in digital systems. The device operates with standard TTL voltage levels and is optimized for high-speed performance.

### **Features:**  
- **9-Bit Parity Function:** Processes 9 input bits to generate or check parity.  
- **Odd/Even Parity Outputs:** Provides both even (ΣE) and odd (ΣO) parity outputs.  
- **High-Speed Operation:** Fast propagation delay (7.5 ns typical).  
- **TTL Compatibility:** Works with standard TTL logic levels.  
- **Low Power Consumption:** Efficient power usage for the AS logic family.  
- **Wide Operating Voltage:** Supports 4.5V to 5.5V supply range.  
- **Industrial Standard Package:** Available in a 14-pin SOIC package.

Application Scenarios & Design Considerations

9-Bit Parity Generators/Checkers

Alternative Part Number

  • MC74ACT280DR2G --: Direct functional equivalent 9-bit odd/even parity generator/checker in the same SOIC-14 package, widely available and pin-compatible.
  • CD74ACT280M96 --: Same-function parity generator/checker from TI's ACT family, offering similar speed and drive with a different series prefix for easy distinction.
  • 74ACT280SCX --: Alternate ACT-family 9-bit parity generator/checker in SOIC-14, suitable drop-in replacement with comparable propagation delay.
