Disadvantages: - Limited maximum clock frequency compared to some newer ICs - Propagation delay may affect timing-sensitive applications

Working Principles

The MC74HCT573AN is an octal latch that stores data based on the clock signal. When the clock signal (CP) rises, the input data (D0-D7) is latched and stored in the corresponding output latch. The stored data can then be read from the outputs (Q1-Q7). The Output Enable (OE) pin controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The MC74HCT573AN can be used in various digital applications, including but not limited to: - Data storage and retrieval systems - Address decoding circuits - Bus interface units - Register banks - Memory modules
