74ALVC574BQ,115

Overview

The Nexperia 74ALVC574BQ,115 is an 8-bit D-type flip-flop with a positive-edge trigger, housed in a 20-DHVQFN package. It operates within a supply voltage range of 1.65 V to 3.6 V and features non-inverting tri-state outputs. The device exhibits a maximum propagation delay of 2.5 ns at 3.3 V with 50 pF load, supporting clock frequencies up to 200 MHz. Output drive capability is specified at ±24 mA, while static current consumption remains low at 20 µA maximum. It functions reliably across an extended temperature range from -40 °C to +85 °C.
