The 74HCT74N is a high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL). Manufactured by NXP Semiconductors, this integrated circuit is part of the 74HCT family, which is known for its high noise immunity and low power consumption. The 74HCT74N is a dual positive-edge triggered D-type flip-flop with individual data (D), clock (CP), set (SD), and reset (RD) inputs; and outputs (Q and Q̅).

This component is designed for use in applications requiring storage and retrieval of binary data. The flip-flops hold stable in a high or low state until the next clock cycle when the D input has been sampled. The set and reset inputs are asynchronous, allowing for immediate changes in state independent of clock signals, which is useful for initialization or emergency halts in digital systems.

The 74HCT74N is housed in a 14-pin DIP (Dual In-line Package), which makes it suitable for through-hole mounting, a method still favored in prototyping and educational environments. The device operates over a wide voltage range from 4.5V to 5.5V, making it compatible with TTL logic levels while benefiting from CMOS technology's lower power consumption and increased noise immunity.

Key features of the 74HCT74N include:

• Complies with JEDEC standard no. 7A
