Description and Introduction

Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs The SN74HCT574PW is a high-speed octal D-type flip-flop manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Technology Family:** HCT (High-Speed CMOS, TTL-Compatible)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Number of Channels:** 8 (Octal)  
- **Output Type:** Tri-State  
- **Clock Frequency:** Up to 25 MHz (typical)  
- **Propagation Delay:** 14 ns (max) at 5V  
- **Input Type:** CMOS/TTL-Compatible  
- **Package Type:** TSSOP (PW)  
- **Pin Count:** 20  

### **Descriptions:**  
The SN74HCT574PW is an octal edge-triggered D-type flip-flop with 3-state outputs. It features a common clock (CP) and output enable (OE) control, making it suitable for bus-oriented applications. The device is designed for high-speed operation while maintaining low power consumption.  

### **Features:**  
- **Octal D-Type Flip-Flop:** 8-bit storage with edge-triggered clocking.  
- **3-State Outputs:** Allows direct connection to a bus-organized system.  
- **Buffered Inputs:** Reduces loading effects.  
- **Balanced Propagation Delays:** Ensures consistent timing performance.  
- **TTL-Compatible Inputs:** Works with both CMOS and TTL logic levels.  
- **Low Power Consumption:** Typical ICC of 4 μA (static).  
- **ESD Protection:** Exceeds 2000V per JESD 22.  

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