Working Principles

The 74LVC377D,118 is an octal D-type flip-flop that stores data on the rising edge of the clock signal. The inputs (D0-D7) represent the data to be stored, while the clock input (CLK) controls when the data is latched into the flip-flop. The master reset input (MR) resets all flip-flops to their initial state when activated.

The output enable input (OE#) allows the outputs (Q0-Q7) to be enabled or disabled. When OE# is high, the outputs are in a high-impedance state, effectively disconnecting them from the rest of the circuit. This feature is useful when multiple devices are connected together and only one device should drive the output at a time.

Detailed Application Field Plans

The 74LVC377D,118 is commonly used in various digital systems where the storage and manipulation of data is required. Some application fields include: 1. Microcontrollers and microprocessors 2. Data communication systems 3. Memory modules 4. Industrial automation 5. Automotive electronics
