Description and Introduction

CMOS Digital Integrated Circuit Silicon Monolithic Octal D-Type Flip-Flop with 3-state Output The TC74AC534F is a high-speed CMOS octal D-type flip-flop with 3-state outputs, manufactured by Toshiba. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Logic Family:** AC Series (Advanced CMOS)  
- **Number of Bits:** 8 (Octal)  
- **Logic Type:** D-Type Flip-Flop  
- **Output Type:** 3-State (Tri-State)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **High-Level Output Current:** -24mA  
- **Low-Level Output Current:** 24mA  
- **Propagation Delay Time:** 8.5ns (max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOP-20 (Small Outline Package)  

### **Descriptions:**  
- The TC74AC534F is an octal edge-triggered flip-flop with 3-state outputs.  
- It features a common clock (CP) and output enable (OE) control.  
- Data is transferred on the **positive edge** of the clock pulse.  
- Outputs enter a high-impedance state when OE is high.  

### **Features:**  
- **High-Speed Operation:** Optimized for performance with low power consumption.  
- **Wide Operating Voltage:** Supports 2.0V to 5.5V, making it compatible with TTL levels.  
- **3-State Outputs:** Allows bus-oriented applications.  
- **Balanced Propagation Delays:** Ensures reliable timing performance.  
- **Low Power Consumption:** Typical ICC of 4μA (max) at 5.5V.  
- **Latch-Up Performance:** Exceeds 300mA per JESD 78.  

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