Functional Features

• The DM74AS374WMX is an octal D-type flip-flop with tri-state outputs.
• It operates at high speeds, making it suitable for applications requiring quick data storage and retrieval.
• The tri-state outputs allow multiple devices to be connected to a common bus, enabling efficient data sharing.

Advantages and Disadvantages

Advantages

• High-speed operation facilitates rapid data processing.
• Low-power consumption helps conserve energy.
• Tri-state outputs enable efficient bus sharing.

Disadvantages

• Limited number of flip-flops (8 in this case) may restrict the complexity of certain applications.
• Operating temperature range (-40°C to +85°C) may not be suitable for extreme environments.

Working Principles

• The DM74AS374WMX operates based on positive-edge triggering. When a clock pulse is received at the CP input, the data present at the D inputs is transferred to the corresponding Q outputs.
• The OE input controls the tri-state outputs. When OE is high, the outputs are enabled and reflect the stored data. When OE is low, the outputs are in a high-impedance state.
