- Simultaneous-Switching Performance of TI Logic Devices (Rev. B)PDF, 378 Kb, Revisión: B, Archivo publicado: feb 23, 2005
Simultaneous-switching noise can generate and propagate glitches in electronic systems. Therefore, system designers are faced with challenges to minimize simultaneous-switching noise, while increasing switching speed and improving signal quality. This report presents the performance of different TI logic devices under various simultaneous-switching conditions. Factors such as the number of bits sw - How to Select Little Logic (Rev. A)PDF, 1.1 Mb, Revisión: A, Archivo publicado: jul 26, 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 Kb, Archivo publicado: dic 1, 1997
This application report explores the possibilities for migrating to 3.3-V and 2.5-V power supplies and discusses the implications.Customers are successfully using a wide range of low-voltage 3.3-V logic devices. These devices are within Texas Instruments (TI) advanced low-voltage CMOS (ALVC) crossbar technology (CBT) crossbar technology with integrated diode (CBTD) low-voltage crossbar techn - Texas Instruments Little Logic Application ReportPDF, 359 Kb, Archivo publicado: nov 1, 2002
Portable and consumer electronic systems? needs present greater challenges today than ever before. Engineers strive to design smaller faster lower-cost systems to meet the market demand. Consequently the semiconductor industry faces a growing need to increase operating speed minimize power consumption and reduce packaging size. Texas Instruments manufactures a variety of Little Logic semicond - Benefits & Issues of Migrating 5-V and 3.3-V Logic to Lower-Voltage Supplies (Rev. A)PDF, 154 Kb, Revisión: A, Archivo publicado: sept 8, 1999
In the last few years the trend toward reducing supply voltage (VCC) has continued as reflected in an additional specification of 2.5-V VCC for the AVC ALVT ALVC LVC LV and the CBTLV families.In this application report the different logic levels at VCC of 5 V 3.3 V 2.5 V and 1.8 V are compared. Within the report the possibilities for migration from 5-V logic and 3.3-V logic families - Advanced High-Speed CMOS (AHC) Logic Family (Rev. C)PDF, 102 Kb, Revisión: C, Archivo publicado: dic 2, 2002
The Texas Instruments (TI) advanced high-speed CMOS (AHC) logic family provides a natural migration for high-speed CMOS (HCMOS) users who need more speed for low-power and low-drive applications. Unlike many other advanced logic families AHC does not have the drawbacks that come with higher speed e.g. higher signal noise and power consumption. The AHC logic family consists of gates medium-sca
