Power-up control, general purpose I/O expansion, voltage level translation and interface bridging are common functions in telecom infrastructure, server and industrial applications. System designers are turning to the use of programmable logic devices (PLDs) to implement these functions in their designs due to the inherent time-to-market and design flexibility advantages they offer over ASICs and ASSPs. By using PLDs in their designs, designers can respond to changing market standards and requirements within a compressed window of opportunity. In addition, PLDs enable designers to reduce the total system cost by integrating discrete logic components combined with a small footprint, minimizing PCB space.
