The SN74ACT74D is a dual D-type flip-flop integrated circuit (IC) component designed for use in digital systems. It belongs to the ACT family of ICs, which are known for their high-speed performance and low power consumption. The SN74ACT74D is specifically designed to operate within a voltage range of 4.5V to 5.5V, making it compatible with standard TTL and CMOS logic levels.
One of the key features of the SN74ACT74D is its dual D-type flip-flop configuration. This means that it contains two independent flip-flops that can store a single bit of digital information each. The device is equipped with a common clock input (CP) and two individual data inputs (D1 and D2) for the two flip-flops. The flip-flops can be clocked simultaneously or independently, making it highly flexible for various digital circuit designs.
Another important feature of the SN74ACT74D is its asynchronous reset capability. The chip provides two reset inputs (CLR1 and CLR2) that allow the user to reset the corresponding flip-flop asynchronously. When a reset signal is applied to a CLR input, it sets the output of the respective flip-flop to a logic low state, regardless of the clock or data inputs. This feature is valuable in applications where a system needs to be initialized or synchronized at specific intervals
