  TI SN74ALVC16835 Component Specification Analysis for PC100
  PDF, 43 Kb, 档案已发布: Aug 3, 1998
  The PC100 standard establishes design parameters for the PC SDRAM DIMM that is designed to operate at 100 MHz. The 168-pin, 8-byte, registered SDRAM DIMM is a JEDEC-defined device (JC-42.5-96-146A). Some of the defined signal paths include data signals, address signals, and control signals. This application report discusses the SN74ALVC16835 18-bit universal bus driver that is available from T

  Bus-Hold Circuit
  PDF, 418 Kb, 档案已发布: Feb 5, 2001
  When designing systems that include CMOS devices, designers must pay special attention to the operating condition in which all of the bus drivers are in an inactive, high-impedance condition (3-state). Unless special measures are taken, this condition can lead to undefined levels and, thus, to a significant increase in the device?s power dissipation. In extreme cases, this leads to oscillation of

  Bus-Interface Devices With Output-Damping Resistors Or Reduced-Drive Outputs (Rev. A)
  PDF, 105 Kb, 修订版: A, 档案已发布: Aug 1, 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

  TI IBIS File Creation Validation and Distribution Processes
  PDF, 380 Kb, 档案已发布: Aug 29, 2002
  The Input/Output Buffer Information Specification (IBIS) also known as ANSI/EIA-656 has become widely accepted among electronic design automation (EDA) vendors semiconductor vendors and system designers as the format for digital electrical interface data. Because IBIS models do not reveal proprietary internal processes or architectural information semiconductor vendors? support for IBIS con

  Live Insertion
  PDF, 150 Kb, 档案已发布: Oct 1, 1996
  Many applications require the ability to exchange modules in electronic systems without removing the supply voltage from the module (live insertion). For example an electronic telephone exchange must always remain operational even during module maintenance and repair. To avoid damaging components additional circuitry modifications are necessary. This document describes in detail the phenomena tha

  CMOS Power Consumption and CPD Calculation (Rev. B)
  PDF, 89 Kb, 修订版: B, 档案已发布: Jun 1, 1997
  Reduction of power consumption makes a device more reliable. The need for devices that consume a minimum amount of power was a major driving force behind the development of CMOS technologies. As a result CMOS devices are best known for low power consumption. However for minimizing the power requirements of a board or a system simply knowing that CMOS devices may use less power than equivale
