Application Notes

  • Advanced Schottky Load Management
    PDF, 277 Kb, File published: Feb 1, 1997
    Designers of high-speed systems that include advanced Schottky (AS) devices must consider the operating environment in their work. They must be aware of the individual device characteristics and their interaction with other devices. This document provides a detailed discussion of the waveform characteristics equivalent circuit models transmission line fanout and termination for AS load manageme
  • Advanced Schottky (ALS and AS) Logic Families
    PDF, 1.9 Mb, File published: Aug 1, 1995
    This document introduces the advanced Schottky family of clamped TTL integrated circuits (ICs). Detailed electrical characteristics of the 'AS and 'ALS devices with table formats are provided. Guidelines for designing high-performance digital systems using the Advanced Schottky family are given along with a brief summary of the solutions to most design decisions needed to implement systems using t
