Working Principles

The 74HC273PW,112 is a positive-edge triggered D-type flip-flop with reset functionality. It can store one bit of data at each flip-flop stage. The clock pulse input (CP) triggers the flip-flop to latch the data present at the data inputs (D0-D7). The master reset input (MR) allows resetting all flip-flops simultaneously when activated. The output enable input (OE) enables or disables the outputs (Q0-Q7) based on its logic level.

Detailed Application Field Plans

The 74HC273PW,112 can be used in various applications, including but not limited to:

1. Digital counters and registers
2. State machines and sequencers
3. Memory address decoding circuits
4. Data storage and retrieval systems
5. Control and timing circuits in microcontrollers
