Overview
The 74LVC74APW/S400118 is a dual D-type flip-flop integrated circuit produced by NXP USA Inc., now part of Nexperia. This component is part of the 74LVC series, known for its low-voltage CMOS logic. It features individual data, clock, set, and reset inputs, along with complementary outputs. The flip-flop is triggered by the positive edge of the clock pulse, and the set and reset inputs are asynchronous and active LOW. This device is highly tolerant of slower input rise and fall times due to Schmitt trigger action at all inputs.
