HCMOS Design Considerations (Rev. A)
PDF, 207 Kb, Revision: A, File published: Sep 9, 2002
This document describes a potential problem designers may encounter when using high-speed CMOS (HC) logic devices. There also is a broad range of CMOS-system to non-CMOS-system interfaces that need to be considered. The design engineer inevitably encounters these interfaces. Key considerations for handling these interfaces are also discussed in this book.
