Partnumber Manufacturer Quantity Availability
SN74AHC574DW 115 In Stock

Description and Introduction

Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs The SN74AHC574DW is an octal edge-triggered D-type flip-flop with 3-state outputs, manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Voltage Supply Range:** 2 V to 5.5 V  
- **High-Level Output Current:** -8 mA  
- **Low-Level Output Current:** 8 mA  
- **Propagation Delay Time:** 9.5 ns (typical at 5 V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SOIC-20  

### **Description:**  
The SN74AHC574DW features eight edge-triggered D-type flip-flops with 3-state outputs. It is designed for bus-oriented applications, allowing multiple outputs to be connected to a common bus without interference. The device operates on a wide voltage range (2 V to 5.5 V), making it suitable for mixed-voltage environments.  

### **Features:**  
- **3-State Outputs** for bus driving applications  
- **Edge-Triggered Clocking** for synchronous operation  
- **Buffered Inputs** reduce input loading  
- **Balanced Propagation Delays** for improved performance  
- **ESD Protection** exceeds 2000 V (HBM)  
- **Latch-Up Performance** exceeds 250 mA per JESD 17  

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