HCF4001M1 – TBC

Overview

The STMicroelectronics HCF4001M1 is a high-performance CMOS dual-input NOR gate, offering four independent gates within a single SOP-14 package. Its primary function is to implement complex combinatorial logic by inverting the logical OR operation. A critical design consideration for this HCF40 logic family part is its relatively high propagation delay of 200 ns, which necessitates careful timing analysis in high-speed digital systems to prevent race conditions, especially when cascaded or used in critical control paths.

Key Features
