Timing Differences of 10-pF Versus 50pF Loading
PDF, 47 Kb, File published: Nov 1, 1996
The 'ALVCH16244 is a 16-bit advanced low voltage CMOS (ALVC) unidirectional driver. Typically, data sheet values for tpd, ten, and tdis are characterized under a 50-pF capacitive load with a temperature range of -40?C to 85?C. At times these drivers are used in memory addressing for dual in-line memory modules (DIMM) with a 10-pF load and and temperature range of 0?C to 70?C. This document provide

TI SN74ALVC16835 Component Specification Analysis for PC100
PDF, 43 Kb, File published: Aug 3, 1998
The PC100 standard establishes design parameters for the PC SDRAM DIMM that is designed to operate at 100 MHz. The 168-pin, 8-byte, registered SDRAM DIMM is a JEDEC-defined device (JC-42.5-96-146A). Some of the defined signal paths include data signals, address signals, and control signals. This application report discusses the SN74ALVC16835 18-bit universal bus driver that is available from T

Logic Solutions for PC-100 SDRAM Registered DIMMs (Rev. A)
PDF, 96 Kb, Revision: A, File published: May 13, 1998
Design of high-performance personal computer (PC) systems that are capable of meeting the needs imposed by modern operating systems and software includes the use of large banks of SDRAMs on DIMMs (see Figure 1).To meet the demands of stable functionality over the broad spectrum of operating environments, meet system timing needs, and to support data integrity, the loads presented by the large

Bus-Hold Circuit
PDF, 418 Kb, File published: 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, Revision: A, File published: Sep 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
