MC74ACT02DG Description

The MC74ACT02DG from onsemi is a high-performance quad 2-input NOR gate integrated circuit (IC) belonging to the 74ACT series, designed for robust digital logic applications. Housed in a 14-pin SOIC package, this surface-mount device operates within a 4.5V to 5.5V supply range, making it ideal for 5V TTL-compatible systems. With a maximum propagation delay of 9.5ns at 5V and 50pF load, it ensures high-speed signal processing, while its low quiescent current (4µA max) enhances power efficiency. The IC features 24mA output drive capability, enabling strong fan-out to multiple loads, and supports TTL-level inputs (0.8V low, 2V high) for seamless interfacing with mixed-logic systems.
