Description and Introduction

Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs The SN74AHC574DBR is a high-speed CMOS 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  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **High-Level Output Current:** -8 mA  
- **Low-Level Output Current:** 8 mA  
- **Propagation Delay Time:** 9.5 ns (typical at 5 V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SSOP (DBR) – 20-pin  

### **Descriptions:**  
The SN74AHC574DBR is designed for bus interface applications, featuring edge-triggered flip-flops with a buffered common clock (CP) and output enable (OE) control. It is compatible with TTL levels and operates at high speeds while maintaining low power consumption.  

### **Features:**  
- **3-State Outputs:** Allow direct connection to a bus-organized system.  
- **Edge-Triggered D-Type Inputs:** Ensures stable data transfer on the rising edge of the clock.  
- **Wide Operating Voltage Range:** Supports 2 V to 5.5 V operation.  
- **Balanced Propagation Delays:** Ensures reliable timing performance.  
- **Low Power Consumption:** Optimized for battery-operated devices.  
- **ESD Protection:** Exceeds 2000 V per JESD 22.  

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