Description and Introduction

CMOS Digital Integrated Circuit Silicon Monolithic 8-Bit Equality Comparator The TC74ACT521F is a high-speed CMOS 8-bit comparator manufactured by Toshiba. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Family:** ACT (Advanced CMOS Technology)  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Input Voltage (VI):** 0V to VCC  
- **Operating Temperature Range:** -40°C to +85°C  
- **Propagation Delay (tpd):** 8.5ns (max) at VCC = 5V, CL = 50pF  
- **Output Current (IO):** ±24mA  
- **Package:** SOP-20 (Small Outline Package, 20-pin)  

### **Descriptions:**  
- The TC74ACT521F is an 8-bit identity comparator that compares two 8-bit binary words (A and B).  
- It features an enable input (E) for output control.  
- The output (P=Q) is active HIGH when both input words match and the enable input is LOW.  

### **Features:**  
- **High-Speed Operation:** Optimized for fast comparison with low propagation delay.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **TTL-Compatible Inputs:** Can interface directly with TTL logic levels.  
- **Wide Operating Voltage Range:** Supports 4.5V to 5.5V operation.  
- **Output Enable Function:** Allows for bus-oriented applications.  
- **High Noise Immunity:** Ensures reliable operation in noisy environments.  

This information is based solely on Toshiba's datasheet for the TC74ACT521F.
