Overview
The 74LVC74AD/S400118 is a dual edge-triggered D-type flip-flop produced by NXP USA Inc. This component features individual data (D) inputs, clock (CP) inputs, set (SD) and reset (RD) inputs, and complementary Q and Q outputs. The set and reset inputs are asynchronous and active LOW, operating independently of the clock input. The flip-flop is triggered on the LOW-to-HIGH transition of the clock pulse, and the data inputs must be stable one set-up time prior to this transition for predictable operation. The device is known for its Schmitt trigger action at all inputs, making it highly tolerant of slower input rise and fall times.
