onsemi 20-SOIC 74AC574SC

The 74AC574SC is an octal D-Type flip-flop IC manufactured by Fairchild (now part of ON Semiconductor). This device features three-state outputs and operates with a supply voltage range typically from 2.0V to 6.0V, supporting both AC and DC power sources. It's designed for high-speed operation in advanced TTL systems, and its 20TSSOP package makes it suitable for surface mount applications. The chip is commonly used in data bus buffering and storage, where its eight independent flip-flops can hold digital data or be triggered by clock inputs.
