Application Notes
- Bus-Interface Devices With Output-Damping Resistors Or Reduced-Drive Outputs (Rev. A)PDF, 105 Кб, Версия: A, Файл опубликован: 1 авг 1997
The spectrum of bus-interface devices with damping resistors or balanced/light output drive currently offered by various logic vendors is confusing at best. Inconsistencies in naming conventions and methods used for implementation make it difficult to identify the best solution for a given application. This report attempts to clarify the issue by looking at several vendors? approaches and discussi - Advanced Schottky (ALS and AS) Logic FamiliesPDF, 1.9 Мб, Файл опубликован: 1 авг 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 - Designing With Logic (Rev. C)PDF, 186 Кб, Версия: C, Файл опубликован: 1 июн 1997
Data sheets which usually give information on device behavior only under recommended operating conditions may only partially answer engineering questions that arise during the development of systems using logic devices. However information is frequently needed regarding the behavior of the device outside the conditions in the data sheet. Such questions might be:?How does a bus driver behave w
