Description and Introduction

Octal binary and BCD identity comparators with enable The SN74F521DW is a high-speed 8-bit identity comparator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** 8-bit Identity/Magnitude Comparator  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Propagation Delay:** 6.5 ns (typical)  
- **Output Type:** TTL-Compatible  
- **Package Type:** SOIC (DW)  
- **Number of Pins:** 20  
- **Current - Output High, Low:** 1mA, 20mA  
- **Function:** Compares two 8-bit binary words (A and B) and provides equality outputs  

### **Descriptions:**  
The SN74F521DW compares two 8-bit binary inputs (A and B) and determines if they are equal. It features active-low outputs for equality comparison and includes enable inputs for cascading multiple devices.  

### **Features:**  
- **High-Speed Operation:** Fast propagation delay for performance-critical applications.  
- **TTL-Compatible Inputs and Outputs:** Ensures compatibility with TTL logic levels.  
- **Enable Inputs (G1, G2):** Allows for cascading multiple comparators.  
- **Active-Low Output (P=Q):** Indicates equality when low.  
- **Wide Operating Voltage Range:** Supports standard 5V logic systems.  
- **Industrial Temperature Range:** Suitable for harsh environments.
