Working Principles

The SN74HC273PWT is a positive-edge-triggered D-type flip-flop. It stores data at the rising edge of the clock pulse (CP) input. The data input (D) is transferred to the output (Q) when the clock pulse rises from low to high. The flip-flop can be asynchronously reset using the master reset (MR) input or set to a known state using the preset (PR) input. The complementary outputs (Q̅ and Q̅) provide inverted versions of the main output (Q).

Detailed Application Field Plans

The SN74HC273PWT is commonly used in various digital systems, including:

  1. Microcontrollers and microprocessors
  2. Communication systems
  3. Data storage devices
  4. Industrial automation equipment
  5. Automotive electronics
  6. Consumer electronics
