Description and Introduction

8-Bit Magnitude Comparators The SN74HC682N is a 8-bit magnitude comparator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** 8-bit Magnitude Comparator  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** PDIP-20 (Plastic Dual In-Line Package)  
- **Propagation Delay:** Typically 19ns at 5V  
- **Input Current (Max):** ±1μA  
- **Output Current (Max):** ±25mA  
- **Number of Pins:** 20  

### **Descriptions:**  
The SN74HC682N compares two 8-bit binary or BCD words and provides outputs indicating whether the first word is greater than, less than, or equal to the second word. It features high-speed operation and low power consumption, making it suitable for arithmetic and control applications.  

### **Features:**  
- **High-Speed CMOS Logic**  
- **Low Power Consumption**  
- **Wide Operating Voltage Range (2V to 6V)**  
- **TTL-Compatible Inputs and Outputs**  
- **Cascadable for Larger Word Sizes**  
- **Three Outputs for Greater Than, Less Than, and Equal To Conditions**  

This device is commonly used in digital systems for comparison operations, such as in microprocessors, calculators, and control logic circuits.
