Working Principles

The 74HC174DB,118 is a hex D-type flip-flop with reset functionality. It operates based on positive-edge triggering of the clock pulse input (CP). The data inputs (D0-D5) are latched into their respective flip-flops when a rising edge is detected on the CP pin. The clear input (CLR) can be used to reset all flip-flops simultaneously. The output enable input (OE) controls the output state, allowing for tri-state outputs.

Detailed Application Field Plans

The 74HC174DB,118 can be used in various applications, including: - Digital counters - Shift registers - Data storage systems - Control circuits - Clock synchronization modules
