  • Provides non-inverting outputs for both flip-flops (Q1 and Q2)
  • Clear (CLR) input resets both flip-flops to a low state
  • Preset (PR) input sets both flip-flops to a high state
  • Clock (CLK) input triggers the flip-flops on the positive edge
  • Asynchronous Set (PRE) and Reset (CLR) inputs override the clock and data inputs

Advantages and Disadvantages

Advantages: - High-speed operation - Reliable performance - Dual flip-flop design for flexibility - Wide operating voltage range

Disadvantages: - Limited number of elements per package - Not suitable for applications requiring negative-edge triggering

Working Principles

The MC74ACT74DTR2 is a dual D-type positive-edge-triggered flip-flop. It stores a single bit of data in each flip-flop, which can be accessed through the non-inverting outputs Q1 and Q2. The flip-flops are triggered by the rising edge of the clock signal (CLK). The state of the flip-flops can be cleared using the Clear (CLR) input or set using the Preset (PR) input. The asynchronous Set (PRE) and Reset (CLR) inputs override the clock and data inputs, allowing for immediate state changes.

Detailed Application Field Plans

The MC74ACT74DTR2 is commonly used in various digital systems and applications, including:

  1. Data storage and retrieval systems
  2. Register circuits
  3. Counters and frequency dividers
