Product Overview: 74HC74DB from NXP
The 74HC74DB is a high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. This integrated circuit is part of the 74HC/HCT family which is known for its versatility and reliability in a wide range of digital applications.
The 74HC74DB is a dual D-type flip-flop that features individual set (SD), reset (RD), clock (CP), and outputs (Q, Q̅). The set and reset are asynchronous active LOW inputs and operate independently of the clock input. The flip-flops are edge-triggered, capturing data on the rising edge of the clock, making them ideal for a variety of edge-triggered applications.
Each flip-flop has independent data (D), clock, set, and reset inputs and Q and Q̅ outputs. This arrangement allows for flexible configurations in various applications such as shift registers, counters, and toggles. The 74HC74DB is capable of operating in a wide voltage range from 2V to 6V, providing compatibility with TTL logic levels while maintaining CMOS low power consumption.
