  • Bus-Hold Circuit
    PDF, 418 Kb, Archivo publicado: 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

    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, Archivo publicado: dic 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, Archivo publicado: 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, Revisión: A, Archivo publicado: agosto 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, Archivo publicado: mayo 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

  • Selecting the Right Level Translation Solution (Rev. A)
    PDF, 313 Kb, Revisión: A, Archivo publicado: jun 22, 2004
    Supply voltages continue to migrate to lower nodes to support today's low-power high-performance applications. While some devices are capable of running at lower supply nodes others might not have this capability. To haveswitching compatibility between these devices the output of each driver must be compliant with the input of the receiver that it is driving. There are several level-translati
  • Live Insertion
    PDF, 150 Kb, Archivo publicado: 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)

    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
