Description and Introduction

CMOS Digital Integrated Circuit Silicon Monolithic Octal D-Type Flip-Flop with 3-State Output The TC74ACT574F is a high-speed CMOS octal D-type flip-flop manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Logic Family:** ACT (Advanced CMOS Technology)  
- **Number of Bits:** 8 (Octal)  
- **Logic Type:** D-Type Flip-Flop  
- **Output Type:** 3-State  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **High-Level Input Voltage (Min):** 2.0V  
- **Low-Level Input Voltage (Max):** 0.8V  
- **High-Level Output Current:** -24mA  
- **Low-Level Output Current:** 24mA  
- **Propagation Delay Time:** 9.5ns (Max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOP-20 (Small Outline Package)  

### **Descriptions:**  
- The TC74ACT574F 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 to the outputs on the positive edge of the clock pulse.  
- The outputs enter a high-impedance state when OE is high.  

### **Features:**  
- **High-Speed Operation:** Compatible with TTL levels and optimized for 5V systems.  
- **3-State Outputs:** Allows bus-oriented applications.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **Wide Operating Voltage Range:** Supports 4.5V to 5.5V operation.  
- **High Noise Immunity:** Stable performance in noisy environments.  

This information is strictly based on Toshiba's datasheet for the TC74ACT574F.

Application Scenarios & Design Considerations

CMOS Digital Integrated Circuit Silicon Monolithic Octal D-Type Flip-Flop with 3-State Output

Alternative Part Number

  • 74ACT574SC --: Same 74ACT octal D flip-flop function with 3-state outputs, pin-compatible SOIC package, widely available and cost-effective.
  • SN74ACT574DW --: Direct functional equivalent in the 74ACT logic family, same octal D-type flip-flop with 3-state outputs in SOIC package.
  • MC74ACT574DWR2G --: Equivalent 74ACT octal D flip-flop with 3-state outputs, SOIC package, good second-source option with strong availability.
  • MC74ACT574DWR2 --: ACT-family octal D flip-flop with 3-state outputs in SOIC-20, suitable drop-in replacement with similar drive and timing.
