Description and Introduction

CMOS Digital Integrated Circuit Silicon Monolithic 8-Bit Equality Comparator The **TC74ACT521P** is a high-speed CMOS 8-bit comparator manufactured by **TOSHIBA**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Logic Family:** ACT (Advanced CMOS Technology)
- **Supply Voltage Range:** 4.5V to 5.5V
- **Operating Temperature Range:** -40°C to +85°C
- **Input Current (Max):** ±1μA
- **Propagation Delay (Max):** 10ns at 5V
- **Output Drive Capability:** 24mA (sink/source)
- **Package Type:** DIP-20 (Plastic Dual In-line Package)
- **Pin Count:** 20

### **Descriptions:**
- The **TC74ACT521P** is an 8-bit identity comparator that compares two 8-bit binary words (A and B) and provides an output indicating whether they are equal.
- It features **enable inputs (G1, G2)** for cascading multiple devices.
- The output is **active-low (P = Q)** when the inputs match and the enable conditions are met.
- Designed for high-speed operation with low power consumption.

### **Features:**
- **High-Speed CMOS Technology:** Ensures fast switching performance.
- **Wide Operating Voltage:** Compatible with TTL levels (5V operation).
- **Low Power Consumption:** Suitable for battery-operated devices.
- **Schmitt Trigger Inputs:** Improves noise immunity.
- **Cascadable:** Multiple devices can be connected using enable inputs.
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing with TTL logic.

This IC is commonly used in digital systems for address decoding, data verification, and control applications.
