Description and Introduction

Octal Non-Inverting D-Type Flip-Flops with 3-State Outputs The CD74ACT574 is a high-speed octal D-type flip-flop with 3-state outputs, manufactured by Harris (now part of Intersil). Key specifications include:  

- **Logic Family**: ACT (Advanced CMOS Technology)  
- **Supply Voltage Range**: 4.5V to 5.5V  
- **High-Speed Operation**: 10ns max propagation delay at 5V  
- **Output Drive Capability**: 24mA sink/source  
- **3-State Outputs**: Allows bus-oriented operation  
- **Edge-Triggered Clocking**: Positive-edge triggered  
- **Operating Temperature Range**: -55°C to +125°C (military grade)  
- **Package Options**: 20-pin PDIP, SOIC, and other surface-mount packages  

The device is compatible with TTL inputs and provides improved noise immunity compared to standard CMOS.  

(Note: Harris Semiconductor was acquired by Intersil, which was later acquired by Renesas Electronics.)
