Frequently Asked Questions

What is the maximum operating frequency of the CD54HC74F3A?

The CD54HC74F3A supports clock frequencies up to 20 MHz when driving a 50 pF load capacitance at nominal supply voltage. This makes it suitable for moderate-speed digital synchronization tasks in industrial and military-grade equipment.

What supply voltage range does the CD54HC74F3A support?

It operates over a supply voltage range of 2 V to 6 V, consistent with the HC logic family standard. This makes it compatible with 3.3 V and 5 V digital logic systems while providing CMOS-level logic thresholds and low power consumption.

Why does the CD54HC74F3A use a ceramic DIP package?

The ceramic DIP-14 package (CDIP) is specified for high-reliability applications requiring extended temperature ranges and resistance to moisture, vibration, and thermal shock. It is the preferred package for military-grade and aerospace electronics where plastic packages may not meet environmental requirements.

Does the CD54HC74F3A have independent set and reset pins?

Yes. Each of the two flip-flop channels has its own active-low set and reset inputs, allowing asynchronous initialization of output states independent of the clock, which is essential for power-on reset and deterministic state initialization in digital circuits.
