MC74AC05DG

MC74AC05DG Description

The MC74AC05DG from onsemi is a high-performance hex inverter IC featuring open-drain outputs, designed for 2V to 6V operation. Part of the 74AC series, it delivers low-power consumption (max 4 µA quiescent current) and high-speed performance, with a maximum propagation delay of 6ns at 5V with 50pF load. This surface-mount device comes in a 14-pin SOIC package and is RoHS3 compliant, making it suitable for modern, eco-conscious designs. Its open-drain architecture allows flexible output configurations, enabling wired-AND logic and direct interfacing with higher-voltage systems.
