ON Semiconductor MC74HC574ADTR2

The MC74HC574ADTR2 is a high-performance integrated circuit from ON Semiconductor, renowned for its reliability and efficiency in a wide range of digital applications. This particular model is a member of the high-speed CMOS family and is designed to operate with the same high speed as LSTTL combined with the true CMOS low power consumption.

The device is an octal D-type flip-flop with 3-state outputs, featuring positive-edge-triggered flip-flops with a direct clear (CLR) input. Each flip-flop is designed to store the state of its individual D-input that occurs with the transition of the clock (CLK) pulse from low to high. The 3-state outputs are controlled by an output enable (OE) input, which, when high, places the eight outputs in a high impedance state. This feature makes the MC74HC574ADTR2 ideal for interfacing with bus-oriented systems where multiple devices may need to share a common data line.

The MC74HC574ADTR2 is supplied in a TSSOP-20 package, which is optimized for reduced space on printed circuit boards, making it suitable for compact designs. Its wide operating voltage range from 2V to 6V and the ability to drive 15 LSTTL loads make it highly versatile for interfacing with various logic families.

Key features of the MC74HC574ADTR2 include:

• High-speed operation comparable to LSTTL
• Low power consumption characteristic of CMOS
• Octal D-type flip-flops with 3-state outputs
• Direct clear input
• Wide operating voltage range (2V to 6V)
• Capability to drive 15 LSTTL loads
• 20-pin TSSOP package for space-saving applications

Applications for the MC74HC574ADTR2 are diverse, including buffer storage, memory address registers, and data storage in a variety of systems such as computers, communication devices, and advanced microprocessor/microcontroller-based systems. Its robust design and ON Semiconductor's commitment to quality make the MC74HC574ADTR2 a dependable choice for designers seeking to enhance the performance and efficiency of their digital logic circuits.
