Description and Introduction

8-BIT EQUALITY COMPARATOR The TC74HCT688AP is a high-speed CMOS 8-bit magnitude comparator manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Logic Family:** HCT (High-Speed CMOS, TTL compatible)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Input Voltage (High):** 2.0V (min)  
- **Input Voltage (Low):** 0.8V (max)  
- **Output Current (High/Low):** ±4mA (min)  
- **Propagation Delay:** 30ns (max) at 4.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 20-pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The TC74HCT688AP compares two 8-bit binary words (A and B) and determines if they are equal.  
- It features a cascadable input (P=Q) for expanding comparisons to larger word sizes.  
- The output is active-low (LOW when A=B, HIGH when A≠B).  
- Designed for high-speed operation with low power consumption.  

### **Features:**  
- **TTL-Compatible Inputs:** Works with both CMOS and TTL logic levels.  
- **Low Power Consumption:** Typical ICC = 4µA (static).  
- **High-Speed Operation:** Suitable for fast digital systems.  
- **Cascadable Design:** Allows expansion for wider word comparisons.  
- **Schmitt Trigger Inputs:** Improves noise immunity.  

This information is strictly based on Toshiba's datasheet for the TC74HCT688AP.
