Working Principles

The SN74AHCT74PWG4 is a dual D-type positive-edge-triggered flip-flop. It stores and transfers binary data based on the rising edge of the clock signal. The data input (D) is latched into the flip-flop when the clock input (CLK) transitions from LOW to HIGH. The complementary outputs (Q and Q̅) represent the stored data, with Q being the true output and Q̅ being the complement of Q. The asynchronous clear (CLR) and preset (PR) inputs allow for easy initialization of the flip-flop by clearing or setting the stored data.

Detailed Application Field Plans

The SN74AHCT74PWG4 can be used in various digital systems and applications, including but not limited to:

  1. Microprocessors and microcontrollers
  2. Communication systems
  3. Data storage devices
