SN74ACT74D is a high speed flip-flop device with dual D-inputs and a complementary set/reset, designed for use in a wide variety of logic applications. It features low static power dissipation, low propagation delay times, and low levels of jitter and dynamic power dissipation.

The SN74ACT74D is designed to perform logic functions that require fast reset/set capabilities. It is designed to store one bit of information and is used in a variety of applications, including computing, signal processing, telecommunications, and memory applications. It can be used in memory systems, as well as in sequential logic circuits, such as counters, shift registers, and bidirectional shift registers. It is also used in interface logic circuits.

The SN74ACT74D is a logic flip-flop that includes two differential data inputs (D₁ and D₂) and a master control signal (Reset/Set). When the control signal is asserted, the flip-flop is reset (if the signal is active high) or set (if it is active low). On power up, the state of the flip-flop is indeterminate.

The SN74ACT74D is a positive-edge-triggered device, meaning that the data-inputs must be present for a minimum amount of time before being accepted as valid. This minimum amount of time is the “setup time” of the device and is specified in the datasheet for each particular part. As long as the data-inputs are valid for a minimum amount of time, the flip-flop will reliably set or reset.

The SN74ACT74D also has an asynchronous clear control signal. This signal is useful in resetting the flip-flop before the data-inputs can be accepted. It also allows the device to be cleared without having to pause the data-inputs. When the asynchronous clear signal is asserted, the flip-flop is cleared regardless of the state of the data-inputs.

The SN74ACT74D is an important device for numerous logic applications, which make it a widely used component. Its fast reset/set capabilities allow for reliable data-transfer in high speed computing and signal applications. Its asynchronous clear function is especially useful for memory applications.
