Functional Features

The MC74HC374ANG is an octal D-type flip-flop with 3-state outputs. It is designed to store and transfer data in high-speed digital systems. The flip-flop has a clock input (CP) for synchronizing the data transfer, and a master reset (MR) input for clearing all flip-flops simultaneously. The output enable (OE) input allows the outputs to be put into a high-impedance state when not enabled.

Advantages and Disadvantages

Advantages: - High-speed operation - CMOS logic for low power consumption - 3-state outputs for bus-oriented applications - Wide operating voltage range

Disadvantages: - Limited number of flip-flops (8) - Propagation delay time may affect timing-sensitive applications

Working Principles

The MC74HC374ANG operates based on the principles of D-type flip-flops. When the clock input (CP) transitions from low to high, the data inputs (D0-D7) are transferred to the corresponding outputs (Q0-Q7). The master reset (MR) input, when activated, clears all flip-flops, setting their outputs to low. The output enable (OE) input controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The MC74HC374ANG is commonly used in various digital systems where data storage and transfer are required. Some application fields include:

  1. Microcontrollers and microprocessors
  2. Data registers and counters
  3. Address decoders and multiplexers
  4. Memory modules and cache systems
  5. Communication interfaces and protocols
