Description and Introduction

8-Bit Identity Comparators The SN74ALS688 is a 8-bit magnitude comparator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Function:** 8-bit magnitude comparator with enable  
- **Logic Family:** ALS (Advanced Low-Power Schottky)  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Input Type:** TTL-compatible  
- **Output Type:** Active-Low (open-collector)  
- **Propagation Delay:** Typically 15ns  
- **Power Dissipation:** Low power consumption for ALS family  

### **Descriptions:**  
The SN74ALS688 compares two 8-bit binary or BCD words (A and B) and provides an active-low output indicating whether they are equal. It features an enable input (G̅) that, when high, forces the output to a high-impedance state.  

### **Features:**  
- **8-bit comparison** with equality output  
- **Active-Low Enable (G̅)** for three-state control  
- **Open-collector outputs** for wired-AND applications  
- **TTL-compatible inputs**  
- **Low power consumption** typical of ALS technology  
- **High-speed operation** with 15ns typical propagation delay  

For detailed electrical characteristics and pin configurations, refer to the official Texas Instruments datasheet.
