    PDF, 895 Kb, 修订版: B, 档案已发布: May 22, 2002
    TI?s 56-ball MicroStar Jr.E package registered under JEDEC MO-225 has demonstrated through modeling and experimentation that it is an optimal solution for reducing inductance and capacitance improving thermal performance and minimizing board area usage in integrated bus functions. Multiple functions released in the 56-ball MicroStar Jr.E package have superior performance characteristics compa
  • LVC Characterization Information
    PDF, 114 Kb, 档案已发布: Dec 1, 1996
    This document provides characterization information about low-voltage logic (LVL) that operates from a 3.3-V power supply. It addresses the issues of interfacing to 5-V logic ac performance power considerations input and output characteristics and signal integrity for this family of devices.
  • Use of the CMOS Unbuffered Inverter in Oscillator Circuits
    PDF, 796 Kb, 档案已发布: Nov 6, 2003
    CMOS devices have a high input impedance high gain and high bandwidth. These characteristics are similar to ideal amplifier characteristics and hence a CMOS buffer or inverter can be used in an oscillator circuit in conjunction with other passive components. Now CMOS oscillator circuits are widely used in high-speed applications because they are economical easy to use and take significantly
  • 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

  • Power-Up 3-State (PU3S) Circuits in TI Standard Logic Devices
    PDF, 209 Kb, 档案已发布: May 10, 2002
    Many telecom and networking applications require that cards be inserted and extracted from a live backplane without interrupting data or damaging components. To achieve this interface terminals of the card must be electrically isolated from the bus system during insertion or extraction from the backplane. To facilitate this Texas Instruments provides bus-interface and logic devices with features
