onsemi Integrated Circuits (ICs) - Logic - Flip Flops MC74ACT175DR2

The MC74ACT175DR2 is a high-speed quad D flip-flop designed for general flip-flop applications where clock and clear inputs are shared. It features four edge-triggered D flip-flops with individual D inputs and corresponding Q and Q outputs. The device transfers the state of the D inputs to the outputs on the LOW-to-HIGH transition of the clock signal. A Master Reset (MR) input allows for simultaneous clearing of all flip-flops when activated. This flip-flop supports output currents of up to 24 mA and is compatible with TTL logic levels. The recommended operating voltage for the ACT version ranges from 4.5V to 5.5V, with a maximum clock frequency of 187 MHz at 5.0V. The propagation delay from clock to output is as low as 1.5 ns, making it suitable for high-speed applications. The device operates over a temperature range of -40°C to +85°C, ensuring reliability in various environments. Engineers may consider the MC74ACT175DR2 for projects requiring efficient data storage and retrieval with fast switching capabilities.
