Working Principles

The 74HC374DB,118 is an octal D-type flip-flop with 3-state outputs. It operates based on the clock pulse (CP) input and the data inputs (D0-D7). When the CP input transitions from low to high, the data at the D0-D7 inputs is latched and stored in the flip-flop. The stored data is then available at the Q0-Q7 outputs.

The output enable (OE) input controls the 3-state outputs. When OE is low, the outputs are enabled and reflect the stored data. When OE is high, the outputs are in a high-impedance state, effectively disconnecting them from the external circuit.

Detailed Application Field Plans

The 74HC374DB,118 can be used in various applications, including: 1. Data storage and transfer systems 2. Address decoding circuits 3. Bus interface units 4. Register banks 5. General-purpose digital logic circuits
