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 InformationPDF, 114 Кб, Файл опубликован: 1 дек 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 CircuitsPDF, 796 Кб, Файл опубликован: 6 ноя 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 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 - Understanding Advanced Bus-Interface Products Design GuidePDF, 253 Кб, Файл опубликован: 1 май 1996

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 - How to Select Little Logic (Rev. A)PDF, 1.1 Мб, Версия: A, Файл опубликован: 26 июл 2016
TI Little Logic devices are logic-gate devices assembled in a small single- dual- or triple- gate package. Little Logic devices are widely used in portable equipment such as mobile phones MP3 players and notebook computers. Little Logic devices also are used in desktop computers and telecommunications. Little Logic gates are common components for easy PC board routing schematic design and b - Migration From 3.3-V To 2.5-V Power Supplies For Logic DevicesPDF, 115 Кб, Файл опубликован: 1 дек 1997
