74LVC574ABQ,115

Overview

The 74LVC574ABQ,115 is a single D-type flip-flop with positive-edge triggering, manufactured by Nexperia. It features eight bits per element and operates within a supply voltage range of 1.65V to 3.6V. The device provides tri-state, non-inverting outputs capable of sourcing and sinking 24mA. Maximum propagation delay is specified at 7ns when operating at 3.3V with a 50pF load. Static current consumption is limited to 10µA. The component supports clock frequencies up to 200MHz and includes an input capacitance of 5pF. It is housed in a 20-VFQFN package with exposed pad, measuring 4.5x2.5mm, suitable for surface mount installation.
