Functional Features

The MC74HC574ADWR2 is an 8-bit D-type flip-flop with 3-state outputs. It operates on CMOS technology, providing high-speed performance. The flip-flop has a clock pulse input (CP) and a master reset input (MR). It also features an output enable input (OE) to control the 3-state outputs.

Advantages and Disadvantages

Advantages: - High-speed operation - CMOS technology for low power consumption - 3-state outputs for flexible signal routing

Disadvantages: - Limited voltage supply range (2.0V to 6.0V) - Temperature limitations (-40°C to +85°C)

Working Principles

The MC74HC574ADWR2 operates as a D-type flip-flop, storing data at the rising edge of the clock pulse. The master reset input allows for clearing the flip-flop to a known state. The output enable input controls whether the outputs are active or in a high-impedance state.
