The MC74HCT74ADG is an integrated circuit (IC) component that belongs to the HCT family of high-speed CMOS logic devices. It is a dual D-type flip-flop with preset and clear functions, meaning it can store and transfer binary data.
Key features of the MC74HCT74ADG include:
1. Dual Flip-Flops: The IC consists of two individual D-type flip-flops that can operate independently or together. Each flip-flop has two inputs: data (D) and clock (CLK).
2. Data Storage: The MC74HCT74ADG can store binary data at the D input when the clock input is high. This data is then transferred to the Q output upon a positive-edge transition of the clock signal.
3. Preset and Clear Functionality: The IC features preset (PR) and clear (CLR) functions, allowing for additional control over the stored data. When the PR input is low, it forces the Q output to be set to high logic level (1), regardless of other inputs. Conversely, when the CLR input is low, it sets the Q output to low logic level (0), regardless of other inputs.
4. Clock Transition Detection: The MC74HCT74ADG detects positive-edge transitions at the CLK input. The stored data is transferred to the Q output only when the clock signal transitions from low to high
