Working Principles

The SN74AC374NSRE4 is a positive-edge triggered octal D-type flip-flop. It stores and transfers data based on the rising edge of the clock input (CLK). The data inputs (D0-D7) are latched into the flip-flop when the clock signal transitions from low to high. The output enable (OE) pin controls the 3-state outputs (Q0-Q7), allowing them to be either active or in a high-impedance state. The asynchronous clear input (EN) resets the flip-flop, forcing all outputs to a low state.

Detailed Application Field Plans

The SN74AC374NSRE4 is widely used in various digital systems where sequential logic is required. Some common application fields include:

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