What are the key features of CD74HC74E?
- Dual independent D-type flip-flops with separate set and reset inputs enabling two independent storage elements in a single 14-pin DIP package
- HC CMOS technology providing low quiescent current and high noise immunity for reliable operation in noisy digital systems
- Wide supply voltage range of 2V to 6V allowing use in both 3.3V and 5V logic systems with direct TTL compatibility at 5V
- Positive-edge triggering on both flip-flops ensuring predictable synchronous data capture on the rising clock edge for reliable state machine designs
What is CD74HC74E used for?
The CD74HC74E is used in digital circuit designs for frequency division, pipeline registers, and synchronization of asynchronous signals to a system clock in microprocessor-based systems. It is a standard building block in state machines, edge detectors, and shift register stages where positive-edge-triggered D flip-flops with independent set and reset control are required. The through-hole DIP package makes it popular in educational electronics, hobbyist projects, and prototyping where breadboard compatibility and easy manual soldering are preferred.

Frequently Asked Questions
What logic family does the CD74HC74E belong to?
The CD74HC74E belongs to the HC (High-speed CMOS) logic family, which combines CMOS low-power consumption with TTL-compatible input levels and high output drive capability, making it interoperable with both CMOS and TTL logic in 5V systems.
How many flip-flops are in the CD74HC74E?
The CD74HC74E contains two independent D-type positive-edge-triggered flip-flops, each with its own data input, clock input, set, and reset control pins, allowing two separate storage or synchronization functions in a single 14-pin DIP package.
What supply voltage range does the CD74HC74E support?
The CD74HC74E operates across a wide supply voltage range of 2V to 6V, enabling deployment in 3.3V low-power systems as well as standard 5V TTL-compatible digital logic circuits without requiring level shifters or additional interface circuitry.
What package does the CD74HC74E use?
The CD74HC74E is housed in a 14-pin PDIP (Plastic Dual In-Line Package), a through-hole package that is ideal for breadboard prototyping, educational applications, and designs requiring socketed ICs for easy replacement or field service.
Can the CD74HC74E be used for frequency division?
Yes, the CD74HC74E is commonly used as a divide-by-two frequency divider by connecting the inverted output (Q-bar) back to the data input, producing an output clock at half the input frequency, which is useful in clock generation and timing circuits.
