Working Principles

The MC74VHCT573ADTG is an octal D-type flip-flop with 3-state outputs. It operates based on the positive edge of the clock signal (CP). When the latch enable input (LE#) is low, the data inputs (D0-D7) are latched and transferred to the outputs (Q0-Q7) on the rising edge of the clock signal. The output enable input (OE#) controls the 3-state outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

The MC74VHCT573ADTG is commonly used in digital systems where level shifting and data storage are required. Some specific application fields include:

1. Microcontrollers and microprocessors
2. Data communication systems
3. Memory interfacing
4. Industrial automation
5. Automotive electronics
