Description and Introduction

Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs The SN74AHCT574DW is a high-speed octal D-type flip-flop manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Bits:** 8  
- **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)  
- **Propagation Delay Time (tpd):** 12.5 ns (max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SOIC-20 (DW)  

### **Descriptions:**  
- The SN74AHCT574DW is an octal edge-triggered D-type flip-flop with 3-state outputs.  
- It is designed for bus-oriented applications and features a buffered clock (CLK) input and output-enable (OE) control.  
- Data on the D inputs is transferred to the Q outputs on the positive edge of CLK.  
- The outputs are in a high-impedance state when OE is high.  

### **Features:**  
- **High-Speed Operation:** Compatible with TTL levels and optimized for 5V operation.  
- **3-State Outputs:** Allows direct connection to a bus-organized system.  
- **Balanced Propagation Delays:** Ensures reliable performance in high-speed applications.  
- **Low Power Consumption:** Typical ICC of 8µA (max).  
- **ESD Protection:** Exceeds 2000V per JESD 22.  

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