DM74ALS574ASJ Octal D-Type Flip-Flop from ON Semiconductor

The DM74ALS574ASJ is a high-speed, octal D-type flip-flop with a clear function, manufactured by ON Semiconductor, a renowned leader in semiconductor solutions. This integrated circuit (IC) is designed to provide optimal performance in a variety of digital applications that require the storage of eight bits of data. It is a significant component in the realm of digital electronics and is commonly used in systems that require the temporary storage of data, such as computers, registers, and various types of memory units.

The device is characterized by its advanced Low-Power Schottky (ALS) technology, which offers a perfect balance between speed and power consumption. The DM74ALS574ASJ operates at a typical voltage of 5V, making it compatible with TTL (Transistor-Transistor Logic) levels, and it is known for its fast propagation delays and reduced power requirements, ensuring efficient operation in high-speed computing environments.

Each flip-flop has a direct clear input and a data input, which is edge-triggered by a low-to-high transition of the clock input. The outputs of the flip-flops are buffered to lower the drive requirements, providing a better signal integrity. This feature is particularly beneficial when driving the inputs of other ICs, buses, or long cables, where signal strength can be an issue.

The DM74ALS574ASJ comes in a slim 20-pin Small Outline package (SOIC), making it suitable for surface-mount technology (SMT) and ideal for space-constrained applications. This packaging allows for higher density of components on a PCB, optimizing board space without sacrificing performance.

Key features of the DM74ALS574ASJ include:

• Eight D-type flip-flops with clear
• Edge-triggered from low-to-high transitions
• Buffered outputs for enhanced drive capability
• Typical power dissipation of 45 mW
• High-speed operation: tpd = 15 ns (typical) at Vcc = 5V
• Wide operating temperature range: 0°C to 70°C
• Standard 20-pin SOIC package for SMT

Overall, the DM74ALS574ASJ from ON Semiconductor is an excellent choice for designers looking for a reliable and efficient octal flip-flop that can maintain data integrity while operating at high speeds. Its combination of speed, power efficiency, and packaging makes it a versatile component for a wide array of digital logic applications.
