Description and Introduction

8-BIT EQUALITY COMPARATOR The TC74AC521F is a high-speed CMOS 8-bit comparator manufactured by Toshiba. Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
Toshiba  

### **Specifications:**  
- **Logic Family:** AC Series (Advanced CMOS)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **High-Speed Operation:** tpd = 5.5ns (typical) at 5V  
- **Low Power Consumption:** ICC = 4μA (max) at 5.5V  
- **Output Drive Capability:** 24mA at 5V  
- **Input Compatibility:** TTL levels  
- **Package Type:** SOP (Small Outline Package)  
- **Pin Count:** 20  

### **Descriptions:**  
- The TC74AC521F is an 8-bit identity comparator that compares two 8-bit binary words (A and B) and provides an active-low output when they match.  
- It features a cascading input (P) for expanding comparisons to larger word lengths.  
- Designed for high-speed arithmetic and logic operations in digital systems.  

### **Features:**  
- **8-bit Magnitude Comparator:** Compares two 8-bit inputs (A0-A7 and B0-B7).  
- **Active-Low Output:** Outputs a low signal when inputs are identical.  
- **Cascading Capability:** Expandable using the P input for multi-byte comparisons.  
- **Wide Operating Voltage:** Supports 2.0V to 5.5V, making it versatile for different logic levels.  
- **TTL-Compatible Inputs:** Ensures compatibility with TTL logic families.  
- **High Noise Immunity:** CMOS technology provides robust noise resistance.  
- **Low Power Consumption:** Suitable for battery-operated devices.  

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