About 74HC74D

The 74HC74D is a dual positive edge-triggered D-type flip-flop that offers reliable digital functionality. It features individual data (nD), clock (nCP), set (nSD), and reset (nRD) inputs, along with complementary nQ and nQ outputs. This IC is part of the 74HC series and operates with CMOS technology, providing efficient performance.

Nexperia manufactures the 74HC74D as part of their HC/UH Series. It is a 1-bit D flip-flop with a positive edge trigger. The SOP14 package allows for surface-mount integration, making it suitable for compact designs. With a voltage supply range of 6V and complementary output capability, this IC provides versatile options for signal manipulation and processing.

The 74HC74D is commonly used in applications where sequential logic operations and state machines are required. Its dual D-type design enables the capture and storage of data, while the positive edge triggering ensures precise timing control. The availability of set and reset inputs allows for flexible configuration and operation.
