74HC74N (Dual D-type flip-flop ) 74155 ±2g/±4g/±8g dynamically selectable full-scaleIntroduction : 74HC74N (Dual D type flip flop with set and reset positive edge trigger). 74HC74 is a dual positive edge triggered D type flip flop. They have individualdata (nD), clock (nCP), set (nSD) and reset (nRD) inputs, and complementary nQ and nQ outputs. Data at the nD input, that meets the set up and hold time requirements on the LOW to HIGH clocktransition, is stored in the flip flop and appears at the nQ output. Schmitt trigger action in
