Description and Introduction

OCTAL D-TYPE FLIP-FLOP WITH 3-STATE OUTPUT The TC74VHC574FW 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:** VHC (Very High-Speed CMOS)  
- **Function:** Octal D-type flip-flop with 3-state outputs  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **High-Speed Operation:** tpd = 4.3 ns (max) at 5V  
- **Low Power Consumption:** ICC = 4 μA (max) at Ta = 25°C  
- **Output Drive Capability:** 8 mA at 5V  
- **Input Voltage Levels:**  
  - High-level input voltage (VIH): 2.0V (min) at VCC = 2.0V  
  - Low-level input voltage (VIL): 0.8V (max) at VCC = 2.0V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-20  

### **Descriptions:**  
- The TC74VHC574FW is an 8-bit edge-triggered flip-flop with 3-state outputs.  
- It features a common clock (CP) and output enable (OE) control.  
- Data is transferred from D-inputs to Q-outputs on the rising edge of the clock.  
- Outputs are in a high-impedance state when OE is high.  

### **Features:**  
- **Wide Operating Voltage Range:** 2.0V to 5.5V  
- **High-Speed CMOS Technology:** Ensures fast switching speeds.  
- **3-State Outputs:** Allows bus-oriented applications.  
- **Balanced Propagation Delays:** Ensures reliable performance.  
- **Pin-Compatible with 74-Series Logic ICs:** Easy replacement in existing designs.  
- **Low Noise and EMI:** Suitable for noise-sensitive applications.  

This information is based on Toshiba's official datasheet for the TC74VHC574FW.
