Description and Introduction

Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs The SN74F574N is an octal edge-triggered D-type flip-flop integrated circuit (IC) manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** D-Type Flip-flop  
- **Number of Bits:** 8  
- **Trigger Type:** Positive Edge  
- **Output Type:** Tri-State  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Output Current (IOH):** -3mA  
- **Low-Level Output Current (IOL):** 24mA  
- **Propagation Delay Time (tpd):** 5.5ns (max) at 5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 20-Pin PDIP (Plastic Dual In-Line Package)  

### **Description:**  
The SN74F574N is a high-speed, octal D-type flip-flop with 3-state outputs. It is designed for bus-oriented applications where multiple devices share a common bus. The flip-flops feature edge-triggered clocking and a buffered common clock (CLK) input.  

### **Features:**  
- **Octal Edge-Triggered Flip-Flops:** Eight D-type flip-flops with individual D inputs and Q outputs.  
- **3-State Outputs:** Allows outputs to be placed in a high-impedance state for bus sharing.  
- **Buffered Clock Input:** Ensures minimal clock skew.  
- **High-Speed Operation:** Optimized for fast data transfer.  
- **Wide Operating Voltage Range:** Supports standard 5V logic levels.  
- **Common Output Enable (OE) Control:** Enables/disables all outputs simultaneously.  

This IC is commonly used in digital systems for data storage, buffering, and bus interfacing applications.
