Overview
The 74HC74PW-Q100 is a dual D-type flip-flop with set and reset inputs, designed and manufactured by Nexperia. This component is part of the 74HC family and is characterized by its positive edge-triggered operation. It features individual data (nD), clock (nCP), set (nSD), and reset (nRD) inputs, along with complementary nQ and nQ outputs. The device is highly tolerant to slower clock rise and fall times due to the Schmitt-trigger action in the clock input.
