- Simultaneous-Switching Performance of TI Logic Devices (Rev. B)PDF, 378 Kb, Revisión: B, Archivo publicado: feb 23, 2005
Simultaneous-switching noise can generate and propagate glitches in electronic systems. Therefore, system designers are faced with challenges to minimize simultaneous-switching noise, while increasing switching speed and improving signal quality. This report presents the performance of different TI logic devices under various simultaneous-switching conditions. Factors such as the number of bits sw - Advanced Schottky (ALS and AS) Logic FamiliesPDF, 1.9 Mb, Archivo publicado: agosto 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
