The CD74AC574E is a D-type flip-flop IC that stores and transfers digital data. It operates based on the positive-edge triggered clock pulse input (CP). When the CP input transitions from low to high, the data present at the D0-D7 inputs is latched and stored in the corresponding flip-flops. The stored data can then be accessed through the Q0-Q7 outputs. The OE (Output Enable) pin controls the output state, allowing for easy data retrieval or isolation.
The CD74AC574E is widely used in various digital systems and applications, including:
These alternative models offer similar functionality and can be used as replacements for the CD74AC574E depending on specific requirements and availability.
