Working Principles

The TC74VHCT573AFTEL is an octal D-type flip-flop that stores and transfers data based on clock pulses. When the clock pulse (CP) is triggered, the input data (D0-D7) is latched and stored in the corresponding flip-flop. The stored data can then be accessed through the output pins (Q0-Q7). The output enable (OE) pin controls the state of the outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

The TC74VHCT573AFTEL is commonly used in digital systems where level shifting and data storage are required. Some specific application fields include: - Microcontrollers and microprocessors - Communication systems - Data acquisition systems - Industrial automation - Consumer electronics
