Description and Introduction

8-Bit Identity Comparators The SN54HC688J is a high-speed 8-bit magnitude comparator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** 8-Bit Magnitude Comparator  
- **Technology:** High-Speed CMOS (HC)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Package Type:** CDIP (Ceramic Dual In-Line Package)  
- **Pin Count:** 20  
- **Propagation Delay:** Typically 19 ns at 5V  
- **Output Type:** Standard  
- **Current - Quiescent (Max):** 8 µA  

### **Descriptions:**  
The SN54HC688J compares two 8-bit binary or BCD words and determines whether they are equal, greater than, or less than each other. It features active-low outputs for equality (P=Q) and cascading inputs for expansion to larger word sizes.  

### **Features:**  
- **High-Speed Operation:** Suitable for fast comparison applications.  
- **Low Power Consumption:** CMOS technology ensures minimal power usage.  
- **Wide Operating Voltage Range:** Supports 2V to 6V operation.  
- **Cascadable:** Can be expanded for larger word comparisons.  
- **Military Temperature Range:** Designed for harsh environments.  
- **Active-Low Outputs:** Facilitates easy interfacing with other logic circuits.  

This device is commonly used in digital systems for arithmetic comparisons, control logic, and data processing.
