DM74ALS874BWMX

Overview

The DM74ALS874BWMX is an octal D-type flip-flop manufactured by onsemi, belonging to the Advanced Low-power Schottky (ALS) logic family. It features positive-edge triggering and three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 35 MHz. Key electrical parameters include a propagation delay of 14ns at 5V with 50pF load, output currents of 2.6mA high and 24mA low, and a static current of 18 mA. It functions as a single element with eight bits per component.
