Working Principles

The CD74HCT173E is a synchronous sequential circuit that stores and transfers data using flip-flops. The inputs D0-D3 hold the data to be stored, while the CP input controls the transfer of data from the inputs to the outputs. The CLR input asynchronously clears all flip-flops, and the MR input resets them synchronously. The complementary outputs Q0-Q3 provide the stored data and its inverted form.

Detailed Application Field Plans

The CD74HCT173E can be used in various digital systems and applications, including but not limited to: - Data storage and transfer in microcontrollers and microprocessors. - State machine design and implementation. - Register-based operations in arithmetic and logic units (ALUs). - Digital communication systems. - Control and timing circuits.
