Description and Introduction

CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC The **TC74HC173AP** is a high-speed CMOS logic IC manufactured by **TOSHIBA**. Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Logic Family:** HC (High-Speed CMOS)  
- **Function:** 4-bit D-type register with 3-state outputs  
- **Supply Voltage Range (VCC):** 2V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Current (Max):** ±1µA  
- **Output Current (Max):** ±5.2mA  
- **Propagation Delay:** 15ns (typical at 5V)  
- **Package Type:** DIP-16 (Plastic Dual In-line Package)  

### **Descriptions:**
- The **TC74HC173AP** is a 4-bit parallel-in/parallel-out register with 3-state outputs.  
- It features a common clock input and asynchronous master reset functionality.  
- The outputs are controlled by two enable inputs (OE1, OE2), allowing high-impedance (3-state) output when disabled.  
- Suitable for bus-oriented applications due to its 3-state output capability.  

### **Features:**
- **High-Speed Operation:** Compatible with TTL levels.  
- **Low Power Consumption:** CMOS technology ensures minimal power usage.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **Wide Operating Voltage:** Supports 2V to 6V, making it versatile for different logic levels.  
- **Asynchronous Reset:** Clears all register outputs independently of the clock.  

This information is derived from the manufacturer's datasheet for the **TC74HC173AP** by **TOSHIBA**.
