Functional Features

The SN74HCT74N offers the following functional features:

• Dual D-type positive-edge-triggered flip-flop with complementary outputs.
• High-speed operation due to CMOS technology.
• Clear and preset inputs for easy initialization.
• Positive-edge triggering for synchronized data transfer.
• Complementary outputs for versatile applications.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data processing. - CMOS technology provides low power consumption. - Dual flip-flop configuration enhances versatility in digital circuits. - Clear and preset inputs simplify initialization.

Disadvantages: - Limited number of flip-flops per IC package. - Requires external clock signal for proper operation. - Not suitable for applications requiring negative-edge triggering.

Working Principles

The SN74HCT74N operates based on positive-edge triggering. When a rising edge is detected at the clock input (CLK1 or CLK2), the data present at the respective data input (D1 or D2) is transferred to the corresponding flip-flop. The outputs (Q1, Q1', Q2, Q2') reflect the state of the flip-flops and can be used as desired. The clear and preset inputs allow for initialization and control of the flip-flop states.
