Working Principles

The SN74AC564DBR is an octal D-type flip-flop with 3-state outputs. It operates on positive-edge triggering, meaning the flip-flops' outputs change state when a rising edge is detected on the clock pulse input (CP). The master reset input (MR) allows all flip-flop outputs to be asynchronously reset to a low state. The output enable input (OE) controls the 3-state outputs, enabling or disabling their functionality.

Detailed Application Field Plans

The SN74AC564DBR is commonly used in various digital logic applications, including but not limited to:

  1. Data storage and transfer systems
  2. Address decoding circuits
  3. Register banks
  4. Memory modules
  5. Bus interface units

Its high-speed operation, low-power consumption, and compact package make it suitable for applications where space and power efficiency are crucial.
