Description and Introduction

Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs The SN74HCT574DW is a high-speed octal D-type flip-flop manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Bits:** 8 (Octal)  
- **Input Type:** Single-Ended  
- **Output Type:** Tri-State, Non-Inverted  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Input Voltage (VIH):** 2V (min)  
- **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **High-Level Output Current (IOH):** -6mA  
- **Low-Level Output Current (IOL):** 6mA  
- **Propagation Delay (tpd):** 28ns (max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC (DW) – 20-pin  

### **Descriptions:**  
The SN74HCT574DW is an octal edge-triggered flip-flop with 3-state outputs. It features a common clock (CP) and output enable (OE) control. Data enters the flip-flop on the low-to-high transition of the clock. The outputs are in a high-impedance state when OE is high.  

### **Features:**  
- **High-Speed CMOS Logic:** Compatible with TTL levels  
- **3-State Outputs:** Allows bus-oriented operation  
- **Edge-Triggered Clocking:** Ensures stable data transfer  
- **Wide Operating Voltage:** 4.5V to 5.5V  
- **Low Power Consumption:** Typical ICC of 8µA  
- **Balanced Propagation Delays:** Optimized for performance  
- **ESD Protection:** Exceeds 2000V per JESD 22  

This information is strictly based on the manufacturer's datasheet.
