Working Principles

The 74HCT273DB,112 is a D-type flip-flop with reset functionality. It stores and transfers data based on the clock signal received at the CP pin. When the clock signal transitions from low to high (positive edge), the data present at the D0-D7 inputs is latched and transferred to the Q0-Q7 outputs. The CLR input, when activated (low), clears the stored data and sets the outputs to a known state.

Detailed Application Field Plans

The 74HCT273DB,112 can be used in various applications that require sequential data storage and transfer. Some potential application fields include:

  1. Digital counters and registers
  2. Data synchronization circuits
  3. State machines and control systems
  4. Address decoding and memory interfacing
  5. Clock division and frequency multiplication circuits
