Working Principles

The 74LVTH574DB,112 is an octal D-type flip-flop with 3-state outputs. It stores and transfers digital data using positive-edge triggered clock pulses. When the clock pulse rises from low to high, the data inputs are latched and stored in the flip-flops. The stored data can then be accessed through the corresponding output pins. The output enable (OE) pin controls the 3-state outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

1. Data storage and transfer in microcontrollers and microprocessors.
2. Memory modules and cache systems.
3. Communication systems and networking devices.
4. Digital signal processing applications.
5. Industrial automation and control systems.
