Description and Introduction

8-BIT EQUALITY COMPARATOR The **TC74AC521P** is a high-speed CMOS 8-bit comparator manufactured by **TOSHIBA**.  

### **Key Specifications:**  
- **Logic Family:** AC (Advanced CMOS)  
- **Number of Bits:** 8-bit  
- **Function:** Identity Comparator (checks if two 8-bit inputs are equal)  
- **Output Type:** Active Low (outputs LOW when inputs match)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **High-Speed Operation:** Suitable for high-performance applications  
- **Low Power Consumption:** Benefits from CMOS technology  
- **Package Type:** DIP (Dual In-line Package)

- **Wide Operating Voltage:** Compatible with TTL levels (5V) and lower voltages  
- **High Noise Immunity:** Improved signal integrity  
- **Latch-Up Performance:** Exceeds 250mA per JESD 78  
- **Pin-Compatible:** Can replace older 74LS521 and similar comparators  

This device is commonly used in digital systems for equality checking between two data words.  

*(Note: Always refer to the official datasheet for precise details before implementation.)*

Application Scenarios & Design Considerations

8-BIT EQUALITY COMPARATOR

Alternative Part Number

  • CD74AC521E --: Same AC-family 8-bit identity comparator in a DIP-20 package, pin-compatible and functionally equivalent to the TC74AC521P.
  • MC74AC521N --: AC-series 8-bit magnitude comparator with identical logic function and DIP-20 pinout, suitable as a direct drop-in replacement.
  • SN74AC521N --: Wide 2V-6V AC logic 8-bit comparator in DIP-20, matching the original function and package for easy substitution.
