Advanced Low-Voltage Technology
PDF, 59 Kb, Archivo publicado: jul 27, 1999
ALVT, the advanced low-voltage logic family, offers high-performance BiCMOS devices that are functional at 3.3-V and 2.5-V V sub CC and have low propagation delay, low static-power consumption, and 64 mA current drive. Other features include 5-V tolerance; auto3-state; bus hold; partial power down, hot insertion, and live insertion; and excellent simultaneous-switching and output-skew performance.

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

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

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
