ON Semiconductor MC74ACT574DTR2 Octal D-Type Flip-Flop

The ON Semiconductor MC74ACT574DTR2 is a high-performance, octal D-type flip-flop with a clear feature, designed for use in a wide range of digital applications. This integrated circuit is part of the high-speed CMOS ACT family and is offered in a TSSOP-20 package, providing a compact footprint for space-constrained applications.

The MC74ACT574DTR2 has eight edge-triggered flip-flops with individual D-type inputs and 3-state outputs. The 3-state outputs are designed to interface with bus-oriented systems, enabling the direct connection to a data bus without the need for external buffering. This allows for efficient data transfer and processing, making it ideal for applications such as data storage, communication systems, and complex computing tasks.

The device operates with a supply voltage range from 4.5V to 5.5V, ensuring compatibility with standard 5V systems. This voltage range provides a good balance between power consumption and performance, suiting both battery-powered and plugged-in devices. The flip-flops are triggered on the rising edge of the clock input signal, allowing for precise timing and synchronization within digital circuits.

One key feature of the MC74ACT574DTR2 is the master reset input, which clears all flip-flops when taken high. This allows for quick initialization or resetting of the system without the need to cycle the power. The input and output structures also support TTL-level input signals, making this device versatile and easy to integrate with existing designs that utilize TTL logic.

The robust design of the MC74ACT574DTR2 ensures that it can withstand electrostatic discharge (ESD) events, with protection circuitry built-in to safeguard the device against damage. Additionally, the device is characterized for operation from -40°C to +85°C, ensuring reliable performance across a wide range of environmental conditions.

In summary, the ON Semiconductor MC74ACT574DTR2 offers a reliable and efficient solution for digital data processing and storage applications. Its high-speed performance, combined with the convenience of 3-state outputs and a master reset function, makes it a versatile choice for designers looking to optimize their digital systems.
