Description and Introduction

Octal D-type Edge-Triggered Flip-Flops With 3-State Outputs The SN74AHCT374PW is a high-speed octal D-type flip-flop with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Voltage Supply:** 4.5V to 5.5V  
- **High-Level Input Voltage (Min):** 2V  
- **Low-Level Input Voltage (Max):** 0.8V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP-20  
- **Propagation Delay (Max):** 14 ns at 5V  
- **Input Capacitance:** 3 pF (Typical)  
- **Output Current (High/Low):** ±8mA  

### **Descriptions:**  
The SN74AHCT374PW features edge-triggered D-type flip-flops with 3-state outputs, designed for bus interface applications. It is compatible with TTL levels and operates at CMOS voltage levels, making it suitable for mixed-voltage systems.  

### **Features:**  
- **3-State Outputs:** Allows direct connection to a bus-organized system.  
- **Edge-Triggered Clocking:** Ensures reliable data transfer.  
- **Buffered Inputs:** Reduces input loading.  
- **Balanced Propagation Delays:** Ensures consistent performance.  
- **Wide Operating Voltage Range:** Supports 4.5V to 5.5V operation.  
- **Low Power Consumption:** Optimized for power-sensitive applications.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  

This device is commonly used in data storage, bus interfacing, and signal buffering applications.
