ON Semiconductor MC74ACT574N Octal D-Type Flip-Flop

The MC74ACT574N is a high-performance, octal D-type flip-flop integrated circuit designed and manufactured by ON Semiconductor. This device features eight edge-triggered flip-flops with individual D-type inputs and 3-state outputs. It is a versatile component suitable for a wide range of applications in digital systems where the storage of binary information is required.

Constructed with advanced CMOS technology, the MC74ACT574N offers robust characteristics that include a high noise immunity and low power consumption, making it an excellent choice for battery-operated and power-sensitive designs. The octal flip-flop operates with a supply voltage ranging from 4.5V to 5.5V, which is compatible with TTL levels, thereby allowing for easy interfacing with other standard logic families.

The IC comes in a standard 20-pin DIP (Dual In-line Package) that ensures easy mounting on printed circuit boards and is suitable for through-hole technology. The MC74ACT574N is designed with features that enhance its functionality and reliability:

• Edge-Triggered Flip-Flops: Each flip-flop is triggered on the rising edge of the clock signal, ensuring precise timing and synchronization within your digital circuit.
• 3-State Outputs: The 3-state output configuration allows for connection to a bus-structured system without the need for external pull-up resistors. This feature also helps in reducing power consumption and enables multiple devices to share the same output lines.
• Input and Output Bus Holders: These built-in bus holders maintain the last active state, preventing floating inputs and undefined outputs, which enhances the stability of the system.
• Direct Clear Input: A direct clear input is provided for each flip-flop, enabling immediate clearing of stored data when necessary.

Whether utilized in data storage, buffer storage, or as shift registers, the MC74ACT574N from ON Semiconductor is designed to meet the demands of high-speed data handling and processing applications. Its reliability and performance make it a preferred choice among electronic design engineers for developing efficient and robust digital systems.
