The MC74HCT74ADR2 is a specific model of flip-flop integrated circuit (IC) manufactured by ON Semiconductor. This IC is designed to provide two D-type flip-flop elements in a single package, each capable of storing one bit of data. It operates on a positive edge-triggered clock signal, making it suitable for various digital logic applications. It is packaged in a compact 14-SOIC form factor, making it ideal for space-constrained applications in digital logic systems.
A flip flop is a fundamental building block in digital electronics storing binary information. The MC74HCT74ADR2 incorporates two D-type flip flops, which means it can simultaneously store two bits of information. Each flip-flop has a D (data) input, a clock input, and a Q (output) pin. The state of the D input is captured and stored at the rising edge of the clock signal, and the stored value is then available at the corresponding Q output.
The positive edge-triggered feature of the MC74HCT74ADR2 means that the stored value is updated only when a rising edge (from low to high) is detected on the clock input. This type of triggering mechanism ensures that the stored value remains stable and unaffected by clock signal fluctuations that occur during other clock cycle periods.
The MC74HCT74ADR2 comes in a 14-SOIC package for Small Outline Integrated Circuit. This package has a width of 0.154 inches (3.90mm), making it compact and suitable for space-constrained applications. The SOIC package is designed for surface-mount technology (SMT), enabling easy integration onto printed circuit boards (PCBs) using automated assembly processes.
The onsemi MC74HCT74ADR2’s Wide Range of Applications:
The MC74HCT74ADR2 flip flop is typically used in digital logic applications such as data storage, state machine design, clock synchronisation, and sequential circuitry. Its positive edge-triggered design and dual flip-flop configuration make it particularly useful in systems requiring synchronised data capture and storage.
