Description and Introduction

Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs The SN74HCT574 is a high-speed octal D-type flip-flop manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Flip-flop  
- **Number of Bits:** 8 (Octal)  
- **Technology:** HCT (High-Speed CMOS, TTL compatible)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **High-Level Input Voltage (Min):** 2V  
- **Low-Level Input Voltage (Max):** 0.8V  
- **Output Current (High/Low):** ±6mA  
- **Propagation Delay (Max):** 24ns at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** SOIC, PDIP, TSSOP  

### **Descriptions:**  
The SN74HCT574 is an edge-triggered flip-flop with 3-state outputs. It features a common clock (CP) and output enable (OE) control, making it suitable for bus interfacing applications. Data is transferred to the outputs on the positive edge of the clock.  

### **Features:**  
- **3-State Outputs:** Allows direct connection to a bus  
- **Buffered Inputs:** Reduces loading effects  
- **Balanced Propagation Delays:** Ensures reliable performance  
- **TTL-Compatible Inputs:** Works with 5V TTL logic levels  
- **Low Power Consumption:** Typical ICC of 80µA  

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